A Wire Rope Is A Machine
With Many Moving Parts.
Hoists
From childhood, many of us have been conditioned
to think of a machine as some device with gears, shafts,
belts, cams, and assorted whirring parts. Yet, by the rules
of physics, an ordinary pry bar is a simple machine, even
though it has only one part.

A wire rope is, in reality, a very complicated machine. A
typical 6 x 25 rope has 150 wires in its strands, all of which
move independently and together in a very complicated
pattern around the core as the rope bends. Clearances
between wires and strands are balanced when a rope is
designed so that proper bearing clearances will exist to
permit internal movement and adjustment of wires and
strands when the rope has to bend. These clearances will
vary as bending occurs, but are of the same range as the
clearances found in automobile engine bearings.
Quite obviously, the grade of wire will affect such things as
strength, resistance to wear, fatigue resistance, corrosion
resistance and so on. Today, the greatest portion of all wire
rope is made from two grades of wire—Extra Improved,
Plow Steel (EIP) and Double Extra Improved Plow Steel
(EEIP). Both are tough, strong, wear-resisting carbon steel,
with EEIP providing about 10% greater tensile strength.
Sometimes wire is plated or galvanized before strands are
formed, where special corrosion or wear characteristics are
desired. Most wire is “Bright”—that is, without any surface
coating or treatment.
The mathematics is simple: Just subtract half the
circumference of a 30" circle from half the circumference
of a 32" circle.
Circumference = π x Diameter
C= 3.1416 x 32 = 100.5312
C = 3.1416 x 30 = 94.2490
6.2931 / 2 = 3.14
Thus, circumference of a 32-inch circle is slightly more than
6-1/4" longer than that of a 30-inch circle. Since a rope only
touches half of a sheave at any time, the length differential
which a rope must accommodate is 3-1/8".

Wire
Rope
By painting stripes around a wire rope as illustrated here,
and actually bending the rope, we can see the movement
of strands as the rope bends. Anytime a rope flexes, this
movement takes place. The sharper the bend, the more
the movement.
Cordage
The extent to which wires move in a rope when it bends is
illustrated by the following example—what actually happens
when you wrap a 1-inch rope over a 30-inch sheave.
Between the point where the rope first touches the sheave
on one side, and where it leaves the sheave on the other
side, the length of rope in contact with the sheave would be
3-1/8 inches shorter than the length of the side away from
the sheave—if the rope did not move and adjust internally
by wires sliding back and forth.
Load
Securement
This change of dimension is achieved by the sliding and
adjusting of the strands in relation to one another, and a
similar sliding and adjusting of the individual wires within
each strand.

By this same reasoning, a 1-inch rope wrapped on a
30-inch hoist, the drum must compensate internally for a

Understanding and accepting the “machine idea” gives a
rope user a greater respect for rope, and enables him to
obtain better performance and longer useful life from rope
applications. Anyone who uses a rope can use it more
efficiently and effectively when he fully understands the

The Parts List of a
Wire Rope Machine
Wire rope consists of three basic components; while few in
number, these vary in both complexity and configuration so
as to produce ropes for specific purposes or characteristics.
The three basic components of a standard wire rope design
are: 1) wires that form the strand, 2) multi-wire strands laid
helically around a core, and 3) the core.
Wire, for rope, is made in several materials and types:
steel, iron, stainless steel, monel and bronze. By far,
the most widely used material is high-carbon steel. This
is available in a variety of grades each of which has
properties related to the basic curve for steel rope wire.
Wire rope manufacturers select the wire type that is most
appropriate for requirements of the finished product.
available ropes always include these abbreviations to
identify the core type.
The Lay
The word “lay” is used to describe three physical
characteristics of wire rope. It is both an engineering term
and a descriptive term. Lay describes:
Grades of wire rope are referred to as extra improved plow
steel (EIP), and double extra improved plow steel (EEIP).
(These steel grade names originated at the earliest stages
of wire rope development and have been retained as
references to the strength of a particular size and grade
of rope.) The plow steel strength curve forms the basis for
calculating the strength of all steel rope wires; the tensile
strength (psi) of any steel wire grade is not constant, it
varies with the diameter and is highest in the smallest wires.
1.The DIRECTION strands “lay” in the rope—
Right or Left. When you look along a rope, strands of a Right Lay make the rope.
2.The RELATIONSHIP between the direction strands lay in the rope and the direction wires lay in the strands. In a Regular Lay rope,
wires lay opposite the direction of the strand. In a Lang Lay rope, wires lay in the same direction as strands.
3.The LENGTH along the rope which one
strand uses to make one complete spiral around the rope core.
The most common finish for steel wire is "bright" or uncoated. Steel wires may also be galvanized, i.e., zinc coated.
"Drawn galvanized" wire has the same strength as bright
wire, but wire "galvanized at finished size" is usually 10%
lower in strength. In certain applications, "tinned" wire is
used, but it should be noted that tin provides no sacrificial,
i.e., cathodic, protection for the steel as does zinc.
A comparison of typical wire rope lays:
A. Right Regular Lay
D. Left Lang Lay B. Left Regular Lay
E. Right Alternate Lay
C. Right Lang Lay
Strands are made up of two or more wires, laid in any one
of many specific geometric arrangements, or in a combination of steel wires with some other materials such as natural
or synthetic fibers. It is conceivable that a strand can be
made up of any number of wires, or that a rope can have any
number of strands. The following section, IDENTIFICATION
and CONSTRUCTION, provides a complete description of
wire rope constructions.

B
The Core is the foundation of a wire rope; it is made of
materials that will provide proper support for the strands
under normal bending and loading conditions. Core materials
include fibers (hard vegetable or synthetic) or steel. A steel
core consists either of a strand or an independent wire rope.
The three most commonly used core designations are: fiber
core (FC), independent wire rope core (IWRC), and wire
strand core (WSC). Catalog descriptions of the various

As a general rule, a strand made up of a small number of
large wires will be more abrasion resistant and less fatigue
resistant than a strand of the same size made up of many
smaller wires.
Warrington
The Warrington Principle is a 2-layer construction
with uniform-sized wires in the inner layer, and
two diameters of wire alternating large and small
in the outer layer. The larger outer-layer wires
rest in the valleys, and the smaller ones on the
crowns, of the inner layer. Example: 19 Warrington
[1-6-(6+6)] strand.
Illustrated on the right are the basic strand
constructions.
Standard Rope Classifications
Most common wire rope constructions are grouped into
four standard classifications, based on the number of
strands and wires per strand, as shown in this chart. All
ropes of the same size and wire grade in each classification
have the SAME strength and weight ratings, and usually
the same pricing. Ropes within each classification may
differ in working characteristics such as abrasion and
fatigue resistance.

Combined Patterns
When a strand is formed in a SINGLE OPERATION using two or more of the above constructions, it is referred to as a “Combined Pattern.”
This example is basically a Seale strand in its first
two layers. The third layer utilizes the Warrington
Principle, and the outer layer is a typical Seale
pattern of same-size wires. It is described: 49
Seale Warrington Seale [1-8-8-(8+8)-16] strand.
Multiple Operation
In contrast to all the above strand types which
are formed in a single operation, a Multiple
Operation construction strand is one in which one
of the above designs is covered with one or more
layers of uniform-sized wires in a different work
operation. The second operation is necessary
because the outer layers must have a different
length of lay or direction of lay. This example is a
Warrington strand overlayed with 18 same-size
wires. It is described: 37 Warrington 2-Operation
[1-6-(6+6)/18] strand.

The Seale Principle features two layers of
wires around a center wire, with the same number
of wires in each layer. All wires in each layer
are the same diameter, and the strand is
designed so that the large outer wires rest in
the valleys between the smaller inner wires.
Example: 19 Seale (1-9-9) strand.
Hardware
Seale

Such physical characteristics as fatigue resistance and
resistance to abrasion are directly affected by the design of
strands. In most strands with two or more layers of wires,
inner layers support outer layers in such a manner that all
wires may slide and adjust freely when the strand flexes.
Wire
Rope
This construction has two layers of uniform size
wire around a center wire, with the inner layer
having half the number of wires as the outer layer.
Small filler wires, equal in number to the inner
layer, are laid in the valleys of the inner layer.
Example: 25 Filler Wire (1-6-6f-12) strand

Strands are basic building blocks. A strand consists of a
“center” which supports a specified number of wires around
it in one or more layers. The strands provide all the tensile
strength of a fiber core rope, and 92-1/2% of the strength of
an IWRC six strand rope.
Load
Securement
What is sometimes called the “Single Layer
Principle” is the basis for this strand construction.
Probably the most common example is a single
wire center with six wires of the same diameter
around it. It is called simply, a 7-wire (1-6) strand.

Classification Ropes
6 x 19 Classification Ropes—
6 x 19S (Seale)
In this construction, each strand has nine
outer wires over nine smaller inner wires over
one large center wire. A comparison of cross
sections shows that these outside wires are
larger than those of 6 x 25FW or 6 x 26WS.
Therefore, its resistance to abrasion is
increased, but its fatigue resistance is
decreased. This is a rope to withstand
abrasion or crushing on the drum.
The 6 x 19 classification of wire ropes includes standard
6 strand, round strand ropes with 16 through 26 wires per
strand. The 6 x 36 classification of wire ropes includes
standard 6 strand, round strand ropes with 27 through
49 wires per strand. Although their operating characteristics
vary, all have the same weight per foot and the same
minimum breaking force, size for size.
6 x 25FW (Filler Wire)
While the 6 x 19 ropes give primary emphasis to abrasion
resistance in varying degrees, the 6 x 36 ropes are
important for their fatigue resistance.
To most wire rope users, 6 x 19 means 6 x 25
filler wire. It was the most common rope in the
6 x 19 classification. This rope has a good
balance between both abrasion resistance and
fatigue resistance in relation to other ropes.
This fatigue resistance is made possible by the greater
number of small wires per strand.
Although there are exceptions for special applications,
the constructions in 6 x 36 classification are primarily
designed to be the most efficient for each rope diameter.
As the rope size increases, for instance, a large number of
wires can be used to achieve required fatigue resistance,
and still those wires will be large enough to offer adequate
resistance to abrasion.
6 x 26WS (Warrington Seale)
This construction has better resistance to
abrasion than a 6 x 25FW. It also features a
compact construction with solid support for the
wires; hence, it has high resistance to crushing.
Its number and relative size of the inner wires
add to the stability of the strand and gives a
fatigue resistance comparable to a 6 x 25FW.
A standard 6 x 26WS construction the best rope
for a wide range of applications. In general,
we recommend the use of a 6 x 26WS in any
application where a 6 x 25FW is used.
6 x 36 Classification Ropes
In most rope sizes, only one 6 x 36 classification
rope is made. These constructions were
selected to provide fatigue resistance without
having wires that are too small. The greater
number of wires in the 6 x 36 classification
makes these ropes more susceptible to
crushing. This can be minimized, however,
by specifying an Independent Wire Rope Core
(IWRC) and by using well-designed sheaves,
grooved drums and proper operating
techniques.

2. Reserve Strength
The best illustration of a design compromise–or best
combination of desired characteristics—is the
interrelationship between resistance to abrasion
and fatigue resistance.
Fatigue resistance (a rope’s capability to bend repeatedly
under stress) is accomplished by using many wires in
the strands. Resistance to metal loss through abrasion is
achieved primarily with a rope design which uses fewer
and, therefore, larger wires in the outer layer to reduce
the effects of surface wear.
Therefore, from a design standpoint, when anything is
done to alter either abrasion resistance or fatigue resistance,
both of these features will be affected.
Abrasion Resistance
The Reserve Strength of a standard rope is a relationship between the strength represented by all the wires in the outer strands and the wires remaining in the outer strands with the outer layer of wires removed. Reserve Strength is calculated using actual metallic areas of the
individual wires. Since there is a direct relationship between metallic area and strength, Reserve Strength is usually expressed as a
percentage of the rope’s minimum breaking force. Reserve Strength
is used as a relative comparison between the internal wire load bearing
capabilities of different rope constructions.
Reserve Strength is an important consideration in selection, inspection and evaluation of a rope for applications where the consequences of a rope failure are great. The use of Reserve Strength is premised on the theory that the outer wires of the strands are the first to be subjected to damage or wear. Therefore, the Reserve Strength figures are less significant when the rope is subjected to internal wear, damage, abuse, corrosion or distortion.
The more wires there are in the outer layer of a strand construction, the greater will be the rope’s Reserve Strength. Geometrically, as more wires are required in the outer layer of a strand, they must be smaller in diameter. This results in greater metallic area remaining to be filled
by the inner wires. Separate columns are shown for standard Fiber Core and IWRC ropes. For Fiber Core ropes, the Reserve Strength is the
approximate percentage of the rope’s metallic area made up by the
inner wires of the outer strands.
An IWRC in a rope is considered to contribute 7-1/2% to the rope’s
total strength. By definition, the core is not included in the Reserve Strength calculation so a 7-1/2% reduction has been made for ropes with an IWRC.
Rotation Resistant ropes, due to their construction, can experience different modes of wear and failure than standard ropes. Therefore,
their Reserve Strength is calculated differently. For Rotation
Resistant ropes, the Reserve Strength is based on the percentage of the metallic area represented by the core strand plus the inner wires of the strands of both the outer and inner layers.

The minimum breaking force applies to new, unused rope. A rope should never operate at, or near, the minimum breaking force. During its
useful life, a rope loses strength gradually due to natural causes, such
as surface wear and metal fatigue.
Hoists
Services
To account for variables which might exist when such tests are made
to determine the breaking strength of a new wire rope an “acceptance” strength may be used. The acceptance strength is 2-1/2% lower
than the minimum breaking force and ropes must meet or exceed
this strength.

Every wire rope has its own “personality” which is a
reflection of its engineered design. Each rope construction
has been established to produce a desired combination
of operating characteristics which will best meet the
performance requirements of the work, or application,
for which that design is intended…and each rope
construction is, therefore, a design compromise.
Wire rope strength is usually measured in tons of 2000 pounds. In published material wire rope strength is shown as minimum breaking force. Minimum breaking force refers to calculated strength figures
that have been accepted by the wire rope industry.

3. Resistance to Metal Loss and Deformation
Metal loss refers to the actual
wearing away of metal from the outer wires of a rope, and metal deformation is the changing
of the shape of outer wires of
a rope.
In general, resistance to metal loss by abrasion (usually called “abrasion resistance”) refers to a rope’s ability to withstand metal being worn away along its exterior. This reduces strength of a rope. Peening causes metal fatigue, which in turn may cause wire failure. The “hammering”, which causes metal of the wire to flow into a new shape, realigns the grain structure of the metal, thereby affecting its fatigue resistance. The out-of-round shape also impairs wire movement when the rope bends.
In a general sense, IWRC ropes are more crush resistant than fiber core ropes. Lang Lay ropes are less crush resistant than
Regular Lay ropes…and 6-strand ropes have greater crush
resistance than 8-strand ropes.
Fatigue resistance involves metal fatigue of the wires that make up a rope. To have high fatigue resistance, wires must be capable of bending repeatedly under stress—
as when a rope passes over
a sheave.
Increased fatigue resistance is achieved in a rope design by using a large number of wires. It involves both the basic metallurgy and the diameters of wires.
In general, a rope made of many wires will have greater fatigue resistance than a same-size rope made of fewer larger wires, because smaller wires have greater ability to bend as the rope
passes over sheaves or around drums. To overcome the effects of
fatigue, ropes must never bend over sheaves or drums with
diameter so small as to kink wires or bend them excessively.
There are precise recommendations for sheave and drum sizes to properly accommodate all sizes and types of ropes.
Every rope is subject to metal fatigue from bending stress while in
operation, and therefore, the rope’s strength gradually diminishes as the rope is used.
6.Bend-ability
The most common form of metal deformation is generally called “peening”—since outside wires of a peened rope appear to have been “hammered” along their exposed surface. Peening usually occurs on drums, caused by rope-to-rope contact during take-up of the rope on the drum. It may also occur on sheaves.
Crushing is the effect of external pressure on a rope, which damages
it by distorting the cross section shape of the rope, its strands or core—
or all three.
Crushing resistance therefore is ability to withstand or resist
external forces, and is a term generally used to express comparison
between ropes.
When a rope is damaged by crushing, the wires, strands and core are prevented from moving and adjusting normally in operation.
Bend-ability relates to the ability of a rope to bend easily if an arc. Four primary factors affect this capability:
1. Diameter of wires that make the rope.
2. Rope and Strand Construction.
3. Metal Composition of wires and finish, such as galvanizing.
4. Type of rope core—fiber or IWRC.
Some rope constructions are by nature more bend-able than
others. Small ropes are more bend-able than big ones. Fiber core ropes bend more easily than comparable IWRC ropes. As a
general rule, ropes made of many wires are more bend-able than same-size ropes made with fewer larger wires.
7.Stability
4. Crushing Resistance
The word “stability” is most often used to describe handling and
working characteristics of a rope. It is not a precise term, since the idea expressed is to some degree a matter of opinion, and is more nearly a “personality” trait than any other rope feature.
For example, a rope is called stable when it spools smoothly on
and off a drum…or doesn’t tend to tangle when a multi-part reeving system is relaxed.
Strand and rope construction contribute most to stability. Preformed rope is usually more stable than nonpreformed, and Lang Lay rope tends to be less stable than Regular Lay. A rope made of simple 7-wire strands will usually be more stable than a more complicated construction with many wires per strand.
There is no specific measurement of ropes have stability.

Again in Figure 1, the first two ("A" and "B") show regular lay ropes. Following these are the types known as lang lay ropes
("C" and "D"). Note that the wires in regular lay ropes appear to line up with the axis of the rope; in lang lay rope the wires
form an angle with the axis of the rope. This difference in appearance is a result of variations in manufacturing techniques:
regular lay ropes are made so that the direction of the wire lay in the strand is opposite to the direction of the strand lay in
the rope; lang lay ropes are made with both strand lay and rope lay in the same direction. Finally, "E," called alternate lay,
consists of alternating regular and lang lay strands.

Lang Lay Ropes
sheaves at or near the critical
tread diameter, not withstanding
the somewhat greater inherent
flexibility of the Lang Lay for
normal service.
Lang Lay Ropes, when properly recommended, installed
and used, have several advantages over Regular Lay
Ropes, but are more subject to abuse. For the same size
and construction, ropes having the same wire sizes and lays,
Lang Lay Ropes are somewhat more flexible than Regular
Lay and have several times the wearing surface per wire to
resist abrasion, as seen in the photo below and in figure on
the right (top). Both ropes shown in the photos have been
ground to the same reduction of rope diameter so as to show
this comparison of the abraded areas of the wires. The Lang
Lay Ropes as usually made are about 15% more flexible
than the same construction Regular Lay, but this value will
vary depending upon the relation of the strand lay to the
rope lay.
Swivels should not be used
with Lang Lay Ropes except
under certain conditions as
individually recommended for
any particular equipment.
Failure to comply with these
foregoing precautions will lead
to very uneconomical rope
service.
While the total area of surface wear on the rope as a
whole is the same for the two types of same construction
ropes for a given depth of wear, the wear on the equipment
and largely the rope service rendered would favor the
Lang Lay construction.
Partially Worn Regular Lay
It is therefore not the total area of worn surface of the rope
as a whole, but the nature of such wear that causes longer
life to the equipment and to the rope where Lang Lay Ropes
can be economically used. To explain this “nature” of wear,
we show both on the photo to the left—lines “a-b,” the line of
contact of a moving rope with the sheave; “a-b” is parallel to
the direction of rope travel, that is, to the longitudinal axis of
the rope.
Partially Worn Lang Lay
Because of the greater wearing surface per wire in the
Lang Lay Ropes, there is less wear on the sheave
and drum equipment.
It will be noted that in the Regular Lay, the line of contact
is axial with one wire; in the Lang Lay (for the 6 x 19 Seale
construction used in this comparison), the line of contact is
diagonally across three worn wires.
On the other hand, very small tread diametered sheaves
or pinching grooves in sheaves are both detrimental to
Lang Lay Ropes, the latter frequently causing “bird-caging”
of the rope.
The shorter exposed length of the worn wires in the
Regular Lay Rope causes these wires to spring up, arching
radially away from the axis of the rope as in figure below.
That causes heavier individual pressure of the wires on the
sheave and an earlier fatigue failure of these wires at the
“neck” of wear due to local reverse bending when the
contact pressure with the sheave depresses this wire.
The stiffer the wire (that is, the higher the strength or grade
of wire), the more pronounced this arching of the wires at
the thinnest worn section or “neck.”
Also, Lang Lay Ropes will crush out of shape more readily
than Regular ropes when winding onto small drums under
heavy winding tension.
The wires of the Regular Lay Ropes are subjected to
higher unit pressure when the rope is passed over sheaves
or drum, causing a somewhat heavier transverse pressure
within the rope structure. Thus the “bending” stresses are
somewhat higher in the Regular Lay Rope and it is
termed “stiffer.”
The mobility of, and capacity of shifting among, the wires
is greater in the Lang Lay; it is this very feature, combined
with the longer exposed length of wires, that causes a
misplacement of the wires in the Lang Lay when bent over

We recommend you store your wire rope under a roof or a weatherproof covering so that moisture cannot reach it.
Similarly, you must avoid acid fumes or any other corrosive atmosphere – including ocean spray – in order to protect the
rope from rust. If you’re storing a reel for a lengthy period, you may want to order your rope with a protective wrap.
If not, at least coat the outer layers of rope with a good rope lubricant.
If you ever take a rope out of service and want to store it for future use, you should place it on a reel after you’ve thoroughly
cleaned and relubricated it. Give the same storage considerations to your used rope as you would your new rope.
Be sure to keep your wire rope in storage away from steam or hot water pipes, heated air ducts or any other source of
heat that can thin out lubricant and cause it to drain out of your rope.

There is always a danger of kinking a wire rope if you improperly unreel or uncoil it. You should mount a reel on jacks or
a turntable so that it will revolve as you pull the rope off. Apply sufficient tension by means of a board acting as a brake
against the reel flange to keep slack from accumulating. With a coil, stand it on edge and roll it in a straight line away from
the free end. You may also place a coil on a revolving stand and pull the rope as you would from a reel on a turntable.

Winding Wire Rope
attached to the drum using the attachment provided. A
tension should be induced into the line by providing some
means of braking the shipping reel. A tight winding is
imperative, particularly if multiple layer winding is required.
Invariably in winding wire rope onto a shipping reel or a
coiling drum, the rope is wound over the top of the reel or
drum. The fact that the rope comes from under the stock
reel to wind reversely on top of the shipping reel has no
effect on the physical condition of the rope, provided the
stock reel is set at least 20 feet, or preferably more,
from the rewinding machine.
When winding a rope onto a grooved drum, the groove will
properly guide the rope. If the rope is to be rewound on a
smooth drum, then a helper should guide the rope, making
sure each turn is winding tightly against the adjacent turn.
A lead or brass hammer is useful in tapping the line over as
it is being wound. Do not use a steel head hammer or pinch
bars. These can readily cause damage to the lines.
The rope should be wound “thread lay,” with close, even
winding throughout the length of the rope. If wound unevenly,
the turns of rope bunch-up, cross wind and are liable to form
doglegs, particularly on the more flexible ropes.
Calculating Drum Capacity
Never fill the reel full to the rim or edge of the flanges.
If possible, leave a clearance equivalent to at least two
layers of rope. This will save injury to the rope when
the reel is rolled over obstructions on the ground.
The length of rope that can be wound on a drum or reel may
be calculated as follows. L = the length of the rope in feet.
All other dimensions are in inches.
The manner in which wire rope is installed or wound on a
drum will, to a large measure, determine the service life of
that rope. Improperly wound ropes will cause undue crushing
of the rope, doglegs, kinks, excessive abrasion and cutting
of the individual wires. Bad spooling also causes uneven
application of force and motion. This results in fast fatiguing
of the line from the end attachment to the drum.
There are five precautionary steps that should be
taken before starting the actual winding of the rope
off the coil or shipping reel.

L = Rope length in feet.
A check should be made of the drum to determine the condition, size and shape of the grooves. If the drum is a smooth type, then the surface should be checked for straightness and smoothness.
Flanges should be checked to determine the extent of undercutting at the base.
Dirt, grit, filled grease or any other type of debris should be cleaned off.
Bearings should be checked.
Cracks or breaks in segments of the drum should
be reported.
Values of K
Whenever any of these five conditions are observed,
the equipment should be removed from service
and properly cleaned, repaired or replaced.
This recommendation is made not just to improve
or maintain good rope life, but to eliminate a
potential hazard.

Multiple layers on a plain (smooth) faced drum crush the
first layer of rope much more than on a grooved drum.
The grooved drum is also recommended to provide
better spooling.
Advancing across the drum on the second layer, the rope,
following the depressions of the first layer, actually
winds back a turn in each revolution of the drum. It
must then cross over two depressions of the first layer
to have a net advance of one turn per revolution.
The correct lay for each winding direction. The direction
of winding on a drum (overwind or underwind) is determined
by standing behind it and looking toward the direction of
rope travel.
This cross over is unavoidable on the second and
succeeding layers. Severe punishment of the rope results
due to abrasion of the adjacent turns against each other
and the crushing from the next layer above at these
points. Parallel and counter-balanced, grooved-controlled,
crossover drums minimize this condition.
When winding only one layer on a smooth drum,
attaching right and left lay ropes as shown in the drawings
below will give the best service.
Multiple Layer Winding
If scrubbing (adjacent wrap contact) is a major problem,
it can be reduced by applying the “winding direction rules”
to the heaviest worked layer instead of the first layer as
shown. To accomplish this, the first layer may or may
not be spooled according to the rule as well.

When a rope winds in the first layer across the face of
a drum, it usually forms a uniform helix. When spooling
on a smooth drum, the first layer helix serves as the
drum lagging for succeeding layers. For continuous
smooth spooling, the first layer should act as a dead layer

These D/d ratios are based on sheave and drum
diameters being approximately 400 times the outer wire

Sheaves, drums and rollers must be of a correct design if
optimum service is to be obtained from both the equipment
and the wire rope. Because there are many different types
of equipment and many different operating conditions, it is
difficult to identify the one specific size of sheave or drum
most appropriate for every application. The guideline to

closely accommodates the limiting factors imposed by the
equipment, the operating conditions and the wire rope.

All wire ropes operating over sheaves and drums are
subjected to cyclic bending stresses, thus the rope wires
will eventually fatigue. The magnitude of these stresses
depends—all other factors being constant—upon the ratio
of the diameter of the sheave or drum to the diameter
of the rope. Frequently, fatigue from cyclic, high-magnitude
bending stress is a principal reason for shortened rope
service. In order for a rope to bend around a sheave, the
rope's strands and wires must move relative to one another.
This movement compensates for the difference in diameter
between the underside and the top side of the rope, the
distance being greater along the top side than it is on the
underside next to the groove. Proper rope movement (and
service) is adversely affected if the wires cannot adjust to
compensate for this length differential. Also, there can
be additional limitations to wire movement because of
excessive pressure caused by a sheave groove diameter
which is too small, or by lack of rope lubrication. Avoid
changing the bending direction from one sheave to another
as this reverse bending further accelerates wire fatigue.

*D = Pitch diameter of sheave
d = nominal diameter of rope
To find any pitch diameter from this table, the diameter for the rope
construction to be used is multiplied by its nominal diameter (d).
For example, the minimum sheave pitch diameter for a 1/2" (nominal
diameter) x 30 (minimum ratio) or 15".
The relationship between sheave diameter and rope
diameter is a critical factor that is used to estimate the
rope's fatigue resistance or relative service life. It is
expressed in the D/d ratio mentioned earlier in which
D is the pitch diameter of the sheave and d is the diameter
of the rope. Table 1 lists suggested minimum D/d values
for various rope constructions. Smaller values can affect
rope life. Table 2 (on next page) shows the effect of
rope construction and D/d on service life.

This service life curve only takes into account bending
and tensile stresses. This curve can be utilized to predict
comparative service life of a specific wire rope with varying
D/d ratios. That resultant comparison is illustrated by the
following example: A rope working with a D/d ratio of 26 has
a relative service life of 17. If the same rope works over a
sheave that increases its D/d ratio to 35, the relative service
life increases to 32. In short, if this rope is used on the
larger sheave, one could estimate an increase in its bending
service life from 17 to 32 or an 88% increase.

Thermal Expansion and Contraction
The coefficient of linear expansion (∝) of steel wire rope is (6.94 x 10-6
per °F) and therefore the change in length of 1 foot of rope produced by
a temperature change of t (°F) would be:
Change in length ∆L = ∆L t where
∝ = coefficient of linear expansion
L = original length of rope (in)
t = temperature change (°F)
The practical value of this characteristic depends upon many factors,
the most important being the type and construction of rope, the range of
loads and the number and frequency of the cycles of operation. It is
not possible to quote exact values for the various constructions of rope
in use, but the following approximate values may be employed to give
reasonably accurate results.
The change will be an increase in length if the temperature rises and a
decrease in length if the temperature falls.

Thermal Expansion =
∆L = ∝L0 t = 6.94 x 106 x 200 x 20 = .33"
Following Phase 1, the rope extends in a manner which complies
approximately with Hookes Law (stress is proportional to strain) until the
limit of proportionality or elastic limit is reached.
It is important to note that wire ropes do not possess a well defined
Young’s Modulus of Elasticity, but an ‘apparent’ Modulus of Elasticity can
be determined between two fixed loads.
The Modulus of Elasticity also varies with different rope constructions,
but generally increases as the cross-sectional area of steel increases.
Therefore, Total Extension =
6" + 5.73" + .33" = 12.06"

At the commencement of loading a new rope, extension is created
by the bedding down of the assembled wires with a corresponding
reduction in overall diameter. This reduction in diameter is
accommodated by a lengthening of the helical lay. When sufficiently
large bearing areas have been generated on adjacent wires to
withstand the circumferential compressive loads, this mechanically
created extension ceases and the extension in Phase 2 commences.
The Initial Extension of any rope cannot be accurately determined
by calculation and has no elastic properties.

The permanent, non-elastic extension of the steel caused by tensile

any further increase of load.

of elastic extension, but if greater accuracy is required, it is advisable to
carry out a modulus test on an actual sample of the rope. As rope users
will find it difficult to calculate the actual metallic steel area, the values
can be found in the Wire Rope Users Manual or obtained from Bridon
Engineering.

The pressure of the rope against the sheave also causes
distortion and flattening of the rope structure. This can be
controlled by using sheaves with the correct groove profile,
which, for general purposes, suggests a recommended
groove diameter of nominal rope diameter +6%. The profile
at the bottom of the groove should be circular over an angle
of approximately 120° and the angle of flare between the
sides of the sheave should be approximately 52°.
Pressures between Ropes and
Sheaves or Drums
In addition to bending stresses experienced by wire ropes
operating over sheaves or pulleys, ropes are also subjected
to radial pressure as they make contact with the sheave.
This pressure sets up shearing stresses in the wires,
distorts the rope’s structure and affects the rate of wear of
the sheave grooves. When a rope passes over a sheave, the
load on the sheave bearing results from the tension in the
rope and the angle of rope contact. It is independent of the
diameter of the sheave.

Industry standards provide minimum design factors allowed
for certain rope applications. Some typical minimum design
factors follow:
It must be realized that this method of estimation of pressure
assumes that the area of contact of the rope in the groove is
on the full rope diameter, whereas in fact only the crowns
of the outer wires are actually in contact with the groove. It
is estimated that the local pressures at these contact points
may be as high as five times those calculated. If the pressure is high, the compressive strength of the material in the
groove may be insufficient to prevent excessive wear and
indentation, and this in turn will damage the outer wires of
the rope and effect its working life. As with bending stresses,
stresses due to radial pressure increase as the diameter
of the sheave decreases. Although high bending stresses
generally call for the use of flexible rope constructions having
relatively small diameter outer wires, these have less ability
to withstand heavy pressures than do the larger wires in the
less flexible constructions. If the calculated pressures are
too high for the particular material chosen for the sheaves or
drums or indentations are being experienced, consideration
should be given to an increase in sheave or drum diameter.
Such a modification would not only reduce the groove
pressure, but would also improve the fatigue life of the rope.

If designers or operators of equipment are seeking
optimum rope performance or regard bending fatigue life
as a key factor in the operation of equipment, such
information can be provided by BRIDON for guidance
purposes.
Bend Fatigue
Bend fatigue testing of ropes usually consists of cycling
a length of rope over a sheave while the rope is under a
constant tension. As part of their ongoing development
program, BRIDON has tested literally thousands of ropes
in this manner over the years on their own in-house
design bend testing equipment.

Other influencing factors, such as dynamic loading,

arrangement, type of spooling on the drum, change in
rope direction, sheave alignment, sheave size and groove
profile, can have an equally dramatic effect on rope

system to prevent rotation in certain operating conditions.
However, this should be done only when employee safety is
the issue.
The Use of Swivels with Wire Rope
These rope constructions, when used in a reeving system
with one end free to rotate, will have a high level of rotation.
This will cause the rope to unlay and, to some degree,
distortion of the rope will occur.
Under certain circumstances it may be necessary to use
a swivel in a lifting system to prevent rotation of the load.
This is typically done for employee safety considerations.
It is possible however, that the use of a swivel will have an
adverse affect on rope performance and may, in some
cases, damage the wire rope.
■
■
Group 3a and 3b
There are many types of accessories available
that incorporate different types and degrees of rotationpreventing swivels. The swivel may be either an
independent accessory or an integral part of a lifting device,
such as a crane block with a swivel hook. A typical
independent accessory is a ball bearing anti-friction swivel.
There are also headache balls with swivel hooks.
The ropes in this Group are designed with an inner rope
that is laid in the opposite direction to the outer strands to
provide a medium resistance to rotation. Ropes with
medium rotation characteristics are used with a swivel in
single part reeving applications. However, a swivel is not
recommended for multiple part hoisting applications or in
any application where the swivel is not necessary for safety
reasons. If it is necessary to use a swivel, the rope must be
operating at a design factor of 5 or greater, must not be
shock loaded and must be inspected daily by a qualified
person for distortion.
The type of swivel that causes the most concern from the
standpoint of the wire rope is the independent anti-friction
swivel that attaches directly to the rope. The purpose of
using a swivel in a lifting system is to prevent rotation of the
load. This then allows the wire rope to rotate. Excessive
rope rotation can damage a wire rope.
It should be noted that if a swivel is used on conjunction
with Group 3a ropes, rope service life might be reduced
due to increased internal wear between the outer strands
and the inner rope.
To assist in determining whether or not a swivel should be
used in the lifting system, the following recommendations
should be considered. It must also be recognized that the
rotation characteristics of different types and constructions
of wire rope vary considerably. The following types and
constructions of wire rope are grouped according to their
rotation characteristics.

Group 4
Group 1
Wire ropes having low rotation characteristics used in either
single or multiple part reeving may be used with a swivel.
The reason for this is that the ropes will exhibit very little, if
any, rotation when used at the proper design factor.
Application parameters, such as a fleet angle, may induce
turn into a wire rope that can be relieved by the use of a
swivel. However, if the application does not induce any turn
into the rope, or if a swivel is not beneficial to the
performance of the rope, the swivel may not be necessary.
Wire rope constructions having very high rotation
characteristics should not be used with a swivel under
any circumstances.
These rope constructions will rotate excessively with one
end free to rotate, and the rope will unlay and distort and
be easily damaged with a loss of rope breaking force.

The problem of torsional instability in crane hoist ropes would not exist
if the ropes could be perfectly torque balanced under load. The torque
generated in a wire rope under load is usually directly related to the
applied load by a constant ‘torque factor’. For a given rope construction,
the torque factor can be expressed as a proportion of the rope diameter
and this has been done below.
If the drum incorporates helical grooving, the helix angle of the groove
needs to be added or subtracted from the fleet angle as described above
to determine the actual fleet angle experienced by the rope.
Variation with rope construction is relatively small and hence the scope
for dramatically changing the stability of a hoisting system is limited.
Nevertheless, the choice of the correct rope can have a deciding influence, especially in systems which are operating close to the critical limit.
It should be noted that the rope torque referred to here is purely that due
to tensile loading. No account is taken of the possible residual torque
due, for example, to rope manufacture or installation procedures.
At the Drum
When spooling rope onto a drum, it is generally recommended that the
fleet angle is limited to between 0.5° and 2.5°. If the fleet angle is too
small, i.e. less than 0.5°, the rope will tend to pile up at the drum flange
and fail to return across the drum. In this situation, the problem may be
alleviated by introducing a ‘kicker’ device or by increasing the fleet angle
through the introduction of a sheave or spooling mechanism.
Torsional Stability
Torsional Stability and the Cabling Graph are two methods which can
be used to determine torsional stability or the tendency of the rope
to cable. The torque factors quoted are approximate maximum values
for the particular constructions. To calculate the torque value for a
particular rope size, multiply by the nominal rope diameter.
If the rope is allowed to pile up, it will eventually roll away from the
flange, creating a shock load in both the rope and the structure of the
mechanism, an undesirable and unsafe operating condition.
Example: for 20mm dia. Dyform 34LR at 20% of minimum
breaking force:
Excessively high fleet angles will return the rope across the drum
prematurely, creating gaps between wraps of rope close to the
flanges, as well as increasing the pressure on the rope at the
cross-over positions.
Torque value Even where helical grooving is provided, large fleet angles will
inevitably result in localized areas of mechanical damage as the wires
‘pluck’ against each other. This is often referred to as ‘interference’,
but the amount can be reduced by selecting a Langs lay rope if the
reeving allows. The “interference” effect can also be reduced by
employing a Dyform rope, which offers a much smoother exterior
surface than conventional rope constructions.
= torque factor x rope dia.
= 0.76% x 20mm
= 0.152mm
To calculate the torque generated in a particular rope when
subjected to a tensile load, multiply the load by the torque value
and combine the units.
Example: for 20mm dia. Dyform 34LR at 6000 kg f load
Torque generated Floating sheaves or specially designed fleet angle compensating devices
may also be employed to reduce the fleet angle effect.
= torque value x load
= 0.152 . 6000

However, for some crane and hoist applications, it is recognized that for
practical reasons. It is not always possible to comply with these general
recommendations, in which case, the rope life could be affected.
Lifting
Products
To reduce the amount of twist to an acceptable level, the fleet angle
should be limited to 2.5° for grooved drums and 1.5° for plain drums and
when using Rotation Resistant, ropes the fleet angle should be limited
to 1.5°.
Fleet angle is usually defined as the included angle
between two lines: one which extends from a fixed sheave
to the flange of a drum, and the other which extends from
the same fixed sheave to the drum in a line perpendicular
to the axis of the drum (see illustration).
Wire
Rope
Of all the factors which have some influence on the
winding of a rope on a smooth drum, the fleet angle,
arguably, has the greatest effect.
Cordage
Fleet Angle
Load
Securement
Where a fleet angle exists as the rope enters a sheave, it initially makes
contact with the sheave flange. As the rope continues to pass through
the sheave it moves down the flange until it sits in the bottom of the
groove. In doing so, even when under tension, the rope will actually roll,
as well as slide. As a result of the rolling action, the rope is twisted,
i.e. turn is induced into or out of the rope, either shortening or lengthening the lay length of the outer layer of strands. As the fleet angle
increases, so does the amount of twist.

Angular Displacement of Block
To predict the amount of angular displacement by which a
sheave block may turn under the influence of rope torque:
sin 0 = (4 000 L. Tv) S2
The torsional characteristics of wire rope will have the effect of causing
angular displacement of a sheave block when used in multi-fall reeving
arrangements. The formula below gives a good approximation under
such arrangements.
The equations assume that rope is torque-free in the noload
condition, therefore, induced torque during or immediately after
installation will adversely influence the calculated effect.
S2 = 4000L. Tv
sin 0
The above data assumes a constant torque value which is a
valid assumption for a new rope. Wear and usage can have
a significant effect on the torque value, but practical work
shows that under such circumstances, the torque value will
diminish, thus improving the stability of the arrangement.
Some arrangements may be of such complexity that the
evaluation demands a computer study.
Where S is the rope spacing in mm
L is the length of each part in the reeving
Tv is the torque value of the rope
0 is the angular displacement of the sheave block
When the angular displacement of the sheave block exceeds 90°
(sin 0 = 1) torsional instability results and ‘cabling’ of the reeving will
occur. Therefore, the test for stability of any particular reeving can be
expressed as:
Examples:
Assuming a pedestal crane working on two falls is roped
with 20mm diameter DYFORM 34LR and the bottom block
carries a sheave of 360mm diameter with the falls parallel:
S>√4000 L. Tv
Torque value = 0.76% x 20 = 0.152mm
Where S is the rope spacing in mm
L is length of each part in meters
Tv is torque value in mm
If the rope is new (worst condition) and no account is taken of block
weight and friction then angular displacement for a height of lift of
30 meters is given by:
The preceding equations are all relative to a simple two part reeving. For
more complex systems, a similar approach may be used if account is
taken of the different spacings of the ropes.

give a resultant below any particular band, the cabling of the
falls will most likely not occur. If the operating conditions

Wire Rope Inspection
The following is a fairly comprehensive listing of critical
inspection factors. It is not, however, presented as
a substitute for an experienced inspector. It is rather a
user’s guide to the accepted standards by which ropes
must be judged.
■
■
■
■
■
1. Abrasion
Rope abrades when it moves through an abrasive medium
or over drums and sheaves. Most standards require
that rope is to be removed if the outer wire wear exceeds
1/3 of the original outer wire diameter. This is not easy to
determine, and discovery relies upon the experience
gained by the inspector in measuring wire diameters of
discarded ropes.
In the past, whether or not a rope was allowed to remain
in service depended to a great extent on the rope’s
diameter at the time of inspection. Currently, this practice
has undergone significant modification.
Internal or external corrosion
Loosening or tightening of rope lay
Inner wire breakage
Rope stretch
Ironing or milking of strands
Previously, a decrease in the rope’s diameter was
compared with published standards of minimum diameters.
The amount of change in diameter is, of course, useful in
assessing a rope’s condition. But, comparing this figure
with a fixed set of values can be misleading. These longaccepted minimums are not, in themselves, of any serious
significance since they do not take into account such factors
as: (1) variations in compressibility between IWRC and Fiber
Core; (2) differences in the amount of reduction in diameter
from abrasive wear, or from core compression, or a
combination of both; and (3) the actual original diameter
of the rope rather than its nominal value
2. Rope Stretch
All ropes will stretch when loads are initially applied. As
a rope degrades from wear, fatigue, etc. (excluding
accidental damage), continued application of a load of
constant magnitude will produce incorrect varying
amounts of rope stretch.
Phase 1: Initial stretch, during the early (beginning) period
of rope service, caused by the rope adjustments to operating
conditions (constructional stretch).
Phase 2: Following break-in, there is a long period—the
greatest part of the rope’s service life—during which a slight
increase in stretch takes place over an extended time. This
results from normal wear, fatigue, etc.
Phase 3: Thereafter, the stretch occurs at a quicker rate.
This means that the rope has reached the point of rapid
degradation; a result of prolonged subjection to abrasive
wear, fatigue, etc. This second upturn of the curve is a
warning indicating that the rope should soon be removed.
As a matter of fact, all ropes will show a significant reduction
in diameter when a load is applied. Therefore, a rope
manufactured close to its nominal size may, when it is
subjected to loading, be reduced to a smaller diameter than
that stipulated in the minimum diameter table. Yet under
these circumstances, the rope would be declared unsafe
although it may, in actuality, be safe.
As an example of the possible error at the other extreme,
we can take the case of a rope manufactured near the
upper limits of allowable size. If the diameter has reached
a reduction to nominal or slightly below that, the tables
would show this rope to be safe. But it should, perhaps,
be removed.
3. Reduction in Rope Diameter
Any marked reduction in rope diameter indicates
degradation. Such reduction may be attributed to:
■ Excessive external abrasion

668
7/3/13 10:07 AM
Because criteria for removal are varied, and because
diameter, in itself, is a vague criterion, the table of minimum
diameters has been deliberately omitted from this manual.
4. Corrosion
Corrosion, while difficult to evaluate, is a more serious cause
of degradation than abrasion. Usually, it signifies a lack of
lubrication. Corrosion will often occur internally before there
is any visible external evidence on the rope surface. Pitting
of wires is a cause for immediate rope removal. Not only
does it attack the metal wires, but it also prevents the rope’s
component parts from moving smoothly as it is flexed.
Usually, a slight discoloration because of rusting merely
indicates a need for lubrication.
9. Heat Damage
After a fire or the presence of elevated temperatures, there
may be metal discoloration or an apparent loss of internal
lubrication; fiber core ropes are particularly vulnerable; under
these circumstances the rope should be replaced.
10. Protruding Core
If, for any cause, the rope core protrudes from an opening
between the strands, the rope is unfit for service and should
be removed.
Severe rusting, on the other hand, leads to premature
fatigue failures in the wires necessitating the rope’s
immediate removal from service. When a rope shows more
than one wire failure adjacent to a terminal fitting, it should
be removed immediately. To retard corrosive deterioration,
the rope should be kept well lubricated with a clear wire
rope lube that can penetrate between strands. In situations
where extreme corrosive action can occur, it may be
necessary to use galvanized wire rope.
11. Damaged End Attachments
Cracked, bent or broken end fittings must be eliminated.
The cause should be sought out and corrected. In the case
of bent hooks, the throat openings—measured at the
narrowest point—should not exceed 5%, not to exceed
1/4" opening and any visibly apparent bend or twist from
the plane of the unbent hook over normal nor should
twisting be greater than 10°.

8. Localized Conditions
Particular attention must be paid to wear at the equalizing
sheaves. During normal operations, this wear is not visible.
Excessive vibration or whip can cause abrasion and/or
fatigue. Drum cross-over and flange point areas must be
carefully evaluated. All end fittings, including splices, should
be examined for worn or broken wires, loose or damaged
strands, cracked fittings, worn or distorted thimbles and
tucks of strands.
Hardware
Deciding whether or not a rope is safe is not always a simple
matter. A number of different but interrelated conditions
must be evaluated. It would be dangerously unwise for an
inspector to declare a rope safe for continued service simply
because its diameter had not reached the minimum
arbitrarily established in a table if, at the same time, other
observations lead to an opposite conclusion.
Lifting
Products
7. “Bird Caging”
Bird caging results from torsional imbalance that comes
about because of mistreatments, such as sudden stops, the
rope being pulled through tight sheaves or wound on too
small a drum. This is cause for rope replacement unless
the affected section can be removed.
Wire
Rope
Core deterioration, when it occurs, is revealed by a more
rapid reduction in diameter and, when observed, it is time
for removal.
Cordage
6. Doglegs
Are permanent bends caused by improper use or
handling. If the dogleg is severe, the sling must be removed
from service. If the dogleg is minor, exhibiting no strand
distortion and cannot be observed when the sling is under
tension, the area of the minor dogleg should be marked for
observation and the sling can remain in service.
Load
Securement
Today, evaluations of the rope diameter are first predicated
on a comparison of the original diameter—when new and
subjected to a known load—with the current reading under
like circumstances. Periodically, throughout the life of the
rope, the actual diameter should be recorded when the
rope is under equivalent loading and in the same operating
section. This procedure, if followed carefully, reveals a
common rope characteristic: after an initial reduction, the
diameter soon stabilizes. Later, there will be a continuous,
albeit small, decrease in diameter throughout its life.
Contractors
Supply
5. Kinks
Are tightened loops with permanent strand distortion that
result from improper handling when a rope is being installed
or while in service. A kink happens when a loop is permitted
to form and then is pulled down tight, causing permanent
distortion of the strands. The damage is irreparable and the
sling must be taken out of service.

On occasion, a single wire will break shortly after installation.
However, if no other wires break at that time, there is
no need for concern. On the other hand, should more wires
break, the cause should be carefully investigated.
12. Peening
Continuous pounding is one of the causes of peening. The
rope strikes against an object, such as some structural part
of the machine, or it beats against a roller or it hits itself.
Often, this can be avoided by placing protectors between
the rope and the object it is striking. Another common cause
of peening is continuous working-under high loads—over a
sheave or drum. Where peening action cannot be controlled,
it is necessary to have more frequent inspections and to be
ready for earlier rope replacement.
On any application, valley breaks—i.e., where the wire
fractures between strands—should be given serious
attention. When two or more such fractures are found, the
rope should be replaced immediately. (Note, however, that
no valley breaks are permitted in elevator ropes.)
It is well to remember that once broken wires appear—in a
rope operating under normal conditions—a good many more
will show up within a relatively short period. Attempting to
squeeze the last measure of service from a rope beyond
the allowable number of broken wires (refer to table on the
next page) will create an intolerably hazardous situation.
13. Scrubbing
Scrubbing refers to the displacement of wires and strands
as a result of rubbing against itself or another object. This,
in turn, causes wear and displacement of wires and strands
along one side of the rope. Corrective measures should be
taken as soon as this condition is observed.
A diagnostic guide to some of the most prevalent rope
abuses are given on the following pages—these abuses are
illustrated and described.
14. Fatigue Fracture
Wires that break with square ends and show little surface
wear have usually failed as a result of fatigue. Such
fractures can occur on the crown of the strands or in the
valleys between the strands where adjacent strand
contact exists. In almost all cases, these failures are
related to bending stresses or vibration.
Below are plain views and cross-sections
show effects of abrasion and peening on wire
rope. Note that a crack has formed as a
result of heavy peening.
Abrasion
Peening
If diameter of the sheaves, rollers or drum cannot be
increased, a more flexible rope should be used. But, if the
rope in use is already of maximum flexibility, the only
remaining course that will help prolong its service life is to
move the rope through the system by cutting off the dead
end. By moving the rope through the system, the fatigued
sections are moved to less fatiguing areas of the reeving.
15. Broken Wires
The number of broken wires on the outside of a wire rope
are an index of (1) its general condition, and (2) whether
or not it must be considered for replacement. Frequent
inspection will help determine the elapsed time between
breaks. Ropes should be replaced as soon as the wire
breakage reaches the numbers given in the chart on the
next page. Such action must be taken without regard
to the type of fracture.
16. Electric Arc
Rope that has either been in contact with a live power line
or been used as “ground” in an electric welding circuit,
will have wires that are fused, discolored and/or annealed
and must be removed.

Guide to Examination
(Continued)
The continued safe operation of lifting equipment, lifting
accessories (e.g. slings) and other systems employing
wire rope depends to a large extent on the operation of
well programmed periodic rope examinations, and the
assessment by the competent person of the fitness
of the rope for further service.

Note: This publication has been prepared as an aid
for rope examination and should not be regarded as a
substitute for the competent person.
G. Sheared End
Wear is a normal feature of rope service, and the use
of the correct rope construction ensures that it remains
a secondary aspect of deterioration. Lubrication may
help to reduce wear.
Factors Affecting Rope Performance
Broken wires are a normal feature of rope service towards
the end of the rope’s life, resulting from bending fatigue
and wear. The local break up of wires may indicate some
mechanical fault in the equipment. Correct lubrication
in service will increase fatigue performance.
Bad spooling (due to excessive fleet angles or slack
winding) can result in mechanical damage, shown as severe
crushing, and may cause shock loading during operation.
Distortions are usually a result of mechanical damage,
and if severe, can considerably affect rope strength.
Visible rusting indicates a lack of suitable lubrication
resulting in corrosion. Pitting of external wire surfaces
becomes evident in some circumstances. Broken wires
ultimately result.
Oversize grooves offer insufficient support to the rope
leading to increased localized pressure, flattening of the
rope and premature wire fractures. Grooves are deemed to
be oversize when the groove diameter exceeds the nominal
rope diameter by more than 15%.
Multi-layers of the rope on the drum can result in severe
distortion in the underlying layers.
Small diameter sheaves can result in permanent set of the
rope and will certainly lead to early wire breaks.
Undersize grooves in sheaves will crush and deform the
rope, often leading to two clear patterns of wear and
associated wire breaks.
Internal corrosion occurs in some environments when
lubrication is inadequate or of an unsuitable type.
Reduction in rope diameter will frequently guide the
observer to this condition. Confirmation can only be made
by opening the rope with clamps or the correct use of spike
and needle to facilitate internal inspection.
Excessive angle of fleet can result in severe wear of the
rope due to scrubbing against adjacent laps on the drum.
Rope deterioration at the Termination may be exhibited in
the form of broken wires. An excessive angle of fleet can
also induce rotation causing torsional imbalance.
Note: Non-destructive testing (NDT) using electromagnetic
means may also be used to detect broken wires and/or loss
in metallic area. This method complements the visual
examination, but does not replace it.

Inspection of
Sheaves & Drums
Figure 1: Cross-sections illustrating three sheave groove
conditions: A is correct, B is too tight and C is too loose.
Under normal conditions, machines receive periodic
inspections and their overall condition is recorded. Such
inspections usually include the drum, sheaves and
any other parts that may come into contact with the
wire rope and subject it to wear. As an additional
precaution, rope-related working parts, particularly in
the areas described below, should be re-inspected
prior to the installation of a new wire rope.
A
The very first item to be checked when examining sheaves
and drums is the condition of the grooves (Figs. 1, 2
and 3). To check the size, contour and amount of wear,
a groove gauge is used. As shown in Figure 1, the gauge
should contact the groove for about 150° of arc.
B
Two types of groove gauges are in general use and it is
important to note which of these is being used. The two differ
by their respective percentage over nominal rope diameter.
C
Figure 2: These sheave groove cross-sections represent
three wire rope seating conditions: A is a new rope in a new
groove, B is a new rope in a worn groove and C is a worn
rope in a worn groove. (See also Figs. 1 and 3)
For new or re-machined grooves, the groove gauge is
nominal plus the full oversize percentage. The gauge carried
by most wire rope representatives today is used for worn
grooves and is made nominal plus 1/2 the oversize
percentage.
This latter gauge is intended to act as a sort of “no-go”
gauge. Any sheave with a groove smaller than this must
be re-grooved or, in all likelihood, the existing rope will
be damaged.
A
When the sheave is re-grooved, it should be machined
to the dimensions for “recommended minimum new
groove” given. Please refer to the Wire Rope Users Manual
or contact your local Lifting Specialist for the table that lists
requirements for new or re-machined grooves. The chart
gives the groove gauge diameter in terms of the nominal
wire rope diameter plus a percentage thereof. Similarly, the
size of the “no-go” gauge is given, against which worn
grooves are judged. Experience has clearly demonstrated
that the service life of the wire rope will be materially
increased by strict adherence to these standards.

Check tension on underlying layers. Bridon recommends an installation tension of between 2% and 10% of the minimum breaking force of the wire rope. Care should be taken to
ensure that tension is retained in service. Insufficient tension will result in these lower layers being more prone to crushing damage.
Review wire rope construction. Dyform wire ropes are more resistant to crushing on underlying layers than conventional rope constructions.
Do not use more rope than necessary.
Check drum diameter. Insufficient bending ratio increases tread pressure.

Check sheave and drum groove radii using sheave gauge to ensure that they are no smaller than nominal rope radius
+2.5%—Bridon recommends that the sheave and drum groove radii are checked prior to any rope installation.
Repair or replace drum / sheaves if necessary.
Check fleet angles in the reeving system—a fleet angle in excess of 1.5 degrees may cause distortion.
Check installation method—turn induced during
installation can cause excessive rope rotation resulting in distortion.
Check if the rope has been cut “on site “ prior to installation
or cut to remove a damaged portion from the end of the rope.
If so, was the correct cutting procedure used? Incorrect

Product Safety:
Instructions & Warnings on
the Use of Steel Wire Rope
The following Instructions and Warnings combine to
provide guidance on Product Safety and are intended for
use by those already having a working knowledge of
wire ropes, as well as the new user. They should be read,
followed and passed on to others.
Failure to read, understand and follow these instructions
could result in harmful and damaging consequences.
1. Rope Selection Criteria
Ensure that the correct type of wire rope is selected for the equipment by referring to the OEM’s instruction manual or other relevant documents. If in doubt, contact Bridon for guidance.
1.1Rope Strength
If necessary, refer to the appropriate Regulations
and/or application standards and calculate the
maximum force to which the rope will be subjected.
The calculation may take into account the mass to be
lifted or moved, any shock loading, effects of high
speed, acceleration, any sudden starts or stops,
frequency of operation and sheave bearing friction.
By applying the relevant design factor and, where
applicable, the efficiency of the rope termination, the
required minimum breaking load or force of the rope
will be determined, the values of which are available
from the relevant National or International standards
or from specific Product Data literature. If in doubt,
ask for advice from Bridon.
1.2 Bending Fatigue
The size and number of sheaves in the system will
influence the performance of the rope.
Wire rope which bends around sheaves, rollers or drums will deteriorate through ‘bending fatigue’.
Reverse bending and high speed will accelerate the process. Therefore, under such conditions select
a rope with high bending fatigue resistance.
Refer to Product Data Information, and if in doubt,
ask for advice.
1.3 Abrasion
Wire rope which is subject to abrasion will become
progressively weaker as a result of:
Externally—dragging it through overburden, sand or
other abrasive materials and passing around a sheave,
roller or drum.
Internally—being loaded or bent.
Abrasion weakens the rope by removing metal from both the inner and outer wires. Therefore, a rope with large outer wires should normally be selected.
1.4 Vibration
Vibration in wire rope will cause deterioration. This
may become apparent in the form of wire fractures
where the vibration is absorbed.
These fractures may be internal only and will not be visually identified.
1.5 Distortion
Wire rope can be distorted due to high pressure
against a sheave, improperly sized grooves or as a
result of multi-layer spooling on a drum.
Rope with a steel core is more resistant to crushing
and distortion.
1.6 Corrosion
Rope with a large number of small wires is more
susceptible to corrosion than rope with a small number of large wires. Therefore, if corrosion is expected to have a significant effect on rope performance. The rope may have to be lubricated frequently in service or a galvanized rope may be selected.
1.7 Cabling
‘Cabling’ of rope reeving due to block rotation can
occur if the rope is incorrectly selected. Applications
involving high lifts are particularly vulnerable to this
condition, therefore, ropes specifically designed to
resist rotation need to be selected.
1.8 Fixing of Rope Ends
Ropes which have high rotation characteristics must
not be selected unless both ends of the rope are fixed
or the load is guided and unable to rotate.
1.9 Connecting Ropes
In the event that it is necessary to connect one rope to
another (in series), it is essential that they have the
required strength, are of the same type and both have
the same lay direction (i.e. connect ‘right’ lay to
‘right’ lay).
Failure to heed this warning could result in
catastrophic failure particularly at a termination, which is capable of being pulled apart (i.e. splice) due to unlaying.
1.10 Rope Length
Rope length and/or difference in length between two
or more ropes used in a set may be a critical factor
and must be considered along with rope selection.

7/3/13 10:07 AM
Do not use ropes with high carbon wires above 800°F.
Failure to observe this general guidance could
result in failure of the ropes to support the load.
Failure to do so may result in the rope becoming
contaminated with foreign matter and start
the onset of corrosion before the rope is even put
to work.
Support the reel on a simple A-frame or cradle located on ground, which is capable of supporting the total mass of rope and reel. Ensure that the rope is stored where it is not likely to be affected by chemical fumes, steam or other corrosive agents.
Failure to do so may seriously affect its condition
rendering it unfit for safe use.
Rope lubricants and any synthetic filling and/or
covering materials may become ineffective at
certain low or high operating temperature levels.
Certain types of rope end terminations also have
limiting operating temperatures and the manufacturer or Bridon should be consulted where there is any doubt. Ropes with aluminium ferrules must not be used at temperatures in excess of 300°F.
2.Storage
2.1 Unwrap the rope and examine the rope
immediately after delivery to check its identification
and condition and verify that it is in accordance
Re-wrap the rope unless it is obvious that this will be
detrimental to rope preservation.
Failure to apply the correct dressing may render the original manufacturing lubricant ineffective and rope performance may be significantly affected.

Ensure that the rope does not make any direct
contact with the floor and that there is a flow of air
under the reel.
2.3 Examine ropes in storage periodically and,
when necessary, apply a suitable dressing which is compatible with the manufacturing lubricant.
Contact the rope supplier, Bridon or original equipment
manufacturer’s (OEM) manual for guidance on types
of dressings available, methods of application and
equipment for the various types of ropes and
applications.
For temperatures over 800°F, other materials, such as
stainless steel or other special alloys, should be
considered.
Hoists
For operating temperatures above 200°F, de-rating of
the minimum breaking force of the rope is necessary
(e.g. between 200°F and 400°F reduce by 10%;
between 400°F and 600°F reduce by 25%; between
600°F and 800°F reduce by 35%).
Never store wire rope in areas subject to elevated
temperatures as this may seriously affect its
future performance. In extreme cases, its original
as-manufactured strength may be severely reduced
rendering it unfit for safe use.

Products
1.12 Operating Temperatures
Wire rope with a steel core should be selected if there
is any evidence to suggest that a fiber core will not
provide adequate support to the outer strands and/or
if the temperature of the working environment may
be expected to exceed 180°F.
Rotate the reel periodically during long periods of
storage, particularly in warm environments, to prevent
migration of the lubricant from the rope.

For the purposes of this instruction, Rotation Resistant ropes should be regarded as non-preformed ropes.

1.11 Preformed and Non-preformed Ropes
Single layer round strand rope is normally supplied
preformed. However, if a non-preformed rope is
selected then personnel responsible for its installation
and/or maintenance need to take particular care

Ensure that the rope is stored and protected in such a
manner that it will not be exposed to any accidental
damage either during the storage period or when
placing the rope in or taking it out of storage.
Failure to carry out or pay attention to any of the above could result in a loss of strength and/or
a reduction in performance. In extreme cases, the rope may be unfit for safe use.
3. Certification and Marking
Make sure that the relevant Certificate has been
obtained before taking the rope into use for a lifting operation.
Check to verify that the marking on the rope or its
package matches the relevant Certificate.
Note: The rating of a component part of a machine
or lifting accessory is the responsibility of the designer of the machine or accessory. Any re-rating of a lifting
accessory must be approved by a competent person.
Retain the Certificate in a safe place for identification
of the rope when carrying out subsequent periodic
statutory examinations in service.
4. Handling and Installation
to the body from wire and rope ends; bruising of the body and damage to limbs due to rope recoil, backlash and any sudden deviation from the line of path of rope.
4.3 Ensure that the correct rope has been supplied
by checking to see that the description on the
Certificate is in accordance with that specified in the purchaser’s order.
4.4 Check by measurement that the nominal diameter of the new rope conforms to the nominal size stated on
the Certificate.
For verification purposes, measure the diameter by
using a suitable rope vernier fitted with jaws broad
enough to cover not less than two adjacent strands.
Take two sets of measurements spaced at least
3′ apart, ensuring that they are taken at the largest cross-sectional dimension of the rope. At each point, take measurements at right angles to each other.
The average of these four measurements should be
within the tolerances specified in the appropriate
Standard or Specification.
For a more general assessment of rope diameter,
use a rope calliper.
4.5 Examine the rope visually to ensure that no
damage or obvious signs of deterioration have taken place during storage or transportation to the
installation site.
4.6 Check the working area around the equipment
for any potential hazards which may affect the safe
installation of the rope.
4.1 Handling and installation of the rope should be
carried out in accordance with a detailed plan and
should be supervised by a competent person.
4.7 Check the condition of the rope-related equipment in accordance with the OEM’s instructions. Include the
following—
Incorrectly supervised handling and installation
procedures may result in serious injury to persons in the vicinity of the operation, as well as those persons directly involved in the handling and installation.
Drum
Check the general condition of the drum.
4.2 Wear suitable protective clothing, such as overalls,
industrial gloves, helmet, eye protectors and safety
footwear (and respirator, particularly where the
emission of fumes due to heat is likely).
If the drum is grooved, check the radius and pitch and ensure that the grooves will satisfactorily accommodate the size of the new rope.
Failure to wear suitable protective clothing and
equipment may result in skin problems from over
exposure to certain types of rope lubricants and
dressings; burns from sparks, rope ends, molten lubricants and metals when cutting ropes or
preparing sockets for re-use; respiratory or other internal problems from the inhalation of fumes when cutting ropes or preparing sockets for re-use; eye injuries from sparks when cutting ropes; lacerations Sheaves

The competent person should be familiar with the
requirements of the appropriate application / machinery standard.
Note: General guidance to users is given in the
Wire Rope Users Manual.
Transfer the wire rope carefully from the storage area
to the installation site.
Coils
Place the coil on the ground and roll it out straight
ensuring that it does not become contaminated with
dust, grit, moisture or any other harmful material.
If the coil is too large to physically handle it may be
placed on a ‘swift’ turntable and the outside end of
the rope pulled out allowing the coil to rotate.
Never pull a rope away from a stationary coil as this
will induce turn into the rope and kinks will form.
These will adversely affect rope performance.
Ensure that the reel stand is mounted so as not to
create a reverse bend during reeving (i.e. for a winch
drum with an overlap rope, take the rope off the top
of the reel).
4.9 Ensure that any equipment or machinery to be roped is correctly and safely positioned and isolated from normal usage before installation commences. Refer to the OEM’s instruction manual and the relevant ‘Code of Practice’.
4.10 When releasing the outboard end of the rope from a reel or coil, ensure that this is done in a
controlled manner. On release of the bindings and
servings used for packaging, the rope will want to straighten itself from its previously bent position.
Unless controlled, this could be a violent action.
Stand clear.
Failure to control could result in injury.
Ensure that the as-manufactured condition of the rope
is maintained during installation.
If installing the new rope with the aid of an old one,
one method is to fit a wire rope sock (or stocking) to
each of the rope ends. Always ensure that the open
end of the sock (or stocking) is securely attached to
the rope by a serving or alternatively by a clip. Connect the two ends via a length of fiber rope of adequate strength in order to avoid turn being transmitted from the old rope into the new rope. Alternatively, a length of fiber or steel rope of adequate strength may be reeved into the system for use as a pilot / messenger line.
Do not use a swivel during the installation of the rope.

4.8 When a new rope is fitted, a variation in size
compared with the old worn rope will be apparent. The new rope may not fit correctly into the previously worn
groove profile and unnecessary wear and rope distortion is likely to occur. This may be remedied by machining out the grooves before the new rope is installed. Before carrying out such action, the sheaves or drum should
be examined to ensure that there will be sufficient strength remaining in the underlying material to safely support the rope.
A kink can severely affect the strength of a
six strand rope and can result in distortion of
a Rotation Resistant rope leading to its
immediate discard.
Services
Engineered
Products
Note: Grooves must have clearance for the rope and provide adequate circumferential support to allow for free movement of the strands and facilitate bending.
When grooves become worn and the rope is pinched at the sides, strand and wire movement is restricted and the ability of the rope to bend is reduced.
If a loop forms in the rope, ensure that it does not
tighten to form a kink.

coiling is involved, it may be necessary for the reel
to be placed in equipment which has the capability of providing a back tension in the rope as it is being
transferred from reel to drum. This is to ensure that
the underlying (and subsequent) laps are wound tightly on the drum.

The products used in the manufacture of steel wire ropes for lubrication and protection present minimal hazard to the user in the form shipped. The user must however, take reasonable care to minimize skin and eye contact and also avoid breathing their vapor and mist.
4.11 Monitor the rope carefully as it is being pulled
into the system and make sure that it is not obstructed by any part of the structure or mechanism which may
cause the rope to come free.
4.13 Ensure that any fittings, such
as clamps or fixtures, are clean and
undamaged before securing rope ends.
Failure to monitor during this operation could
result in injury.
Make sure that all fittings are secure in accordance with the OEM’s instruction manual or manufacturer’s instructions and take particular note of any specific
safety requirements e.g. torque values (and frequency of any re-application
of torque).
This entire operation should be carried out carefully
and slowly under the supervision of a competent
person.
4.12 Take particular care and note the manufacturer’s
instructions when the rope is required to be cut.
Apply secure servings on both sides of the cut mark.
Ensure that the length of serving is at least equal
to two rope diameters. (Note: Special servings are
required for spiral ropes, i.e. spiral strand and
locked coil.)
One serving either side of the cut is normally sufficient for preformed ropes. For non-preformed ropes, (i.e. Rotation Resistant ropes) a minimum of two servings each side of the cut will be necessary.
Arrange and position the rope in such a manner that at the completion of the cutting operation the rope ends will remain in position, thus avoiding any backlash or any other undesirable movement.
Cut the rope with a high speed abrasive disc cutter. Other suitable mechanical or hydraulic shearing
equipment may be used although not recommended when a rope end is required to be welded or brazed.
When using a disc cutter be aware of the danger from sparks, disc fragmentation and fumes.
Ensure adequate ventilation to avoid any build-up of
fumes from the rope and its constituent parts including any fiber core (natural or synthetic) any rope lubricant(s) and any synthetic filling and/or covering material.
Rope produced from carbon steel wires in the
form shipped is not considered a health hazard. During subsequent processing (e.g. cutting,
welding, grinding, cleaning), dust and fumes may
be produced which contain elements which
may affect exposed workers.
When terminating a rope end with a wedge socket, ensure that the rope tail cannot withdraw through the socket by securing a clamp to the tail or by following the manufacturer’s instructions. The tail length should be a minimum of 20 rope diameters for all Rotation
Resistant wire rope and a minimum
of 6 rope diameters for 6 and 8 strand ropes.
(See Fig. 1 for two recommended methods of securing the rope tail of a wedge socket termination).
The loop back method uses a rope grip and the loop
should be lashed to the live part of rope by a soft wire
serving or tape to prevent flexing of the rope in service.
The method of looping back should not be used if
there is a possibility of interference of the loop with the mechanism or structure.
Failure to secure in accordance with instructions could lead to loss of the rope and/or injury.
4.14 When coiling a rope on a plain (or smooth)
barrel drum, ensure that each lap lies tightly against
the preceding lap. The application of tension in
the rope greatly assists in the coiling of the rope.
Any looseness or uneven winding will result in
excessive wear, crushing and distortion of the rope.
With plain barrel drums, it is difficult to achieve
satisfactory multi-layer coiling beyond three layers.

Check that the new rope is spooling correctly on the
drum and that no slack or cross laps develop.
Apply as much tension as possible (2%-5% of the
MBF of the rope) to ensure tight and even spooling,
especially on the first layer.
Where multi-layer spooling is unavoidable, succeeding
layers should spool evenly on the preceding layers
of rope.
Irregular spooling usually results in severe surface wear and rope malformation, which in turn is likely to cause premature rope failure.
4.19 Ensure that the as-manufactured condition of
the rope is maintained throughout the whole of the
handling and installation operation.
4.20 If samples are required to be taken from the
rope for subsequent testing and/or evaluation,
it is essential that the condition of the rope is not
disturbed. Refer to the instructions given in 4.12 and, depending on the rope type and construction, any
other special manufacturer’s instructions.

5.1 Inspect the rope and related equipment at the
beginning of every work period at least daily in most
instances and particularly following any incident which could have damaged the rope or installation.

The entire length of rope should be inspected and
particular attention paid to those sections that
experience has proven to be the main areas of
deterioration. Excessive wear, broken wires, distortion and corrosion are the usual signs of deterioration.
For a more detailed examination, special tools are
necessary, which will also facilitate internal inspection.
In the case of ropes working over drums or sheaves,
it is particularly necessary to examine those areas
entering or leaving the grooves when maximum loads
(i.e. shock loads) are experienced, or those areas
which remain for long periods in exposed places, such
as over a jib head sheave.
On some running ropes, but particularly relevant to
standing ropes (e.g. pendant ropes), the areas adjacent to terminations should be given special attention by
rope diameter measurements and visual examination
for broken wires and corrosion.
Note: Shortening the rope repositions the areas
of maximum deterioration in the system. Where
conditions permit, begin operating with a rope which
has a slightly longer length than necessary in order
to allow for periodic shortening.
When a non-preformed rope or multi-layer rope is
used with a wedge socket and is required to be
shortened, it is essential that the end of the rope is
secured by welding or brazing before the rope is
pulled through the main body of the socket to
its new position.
Failure to observe this instruction will result in
a significant deterioration in the performance
of the rope and could render the rope completely
unfit for further service.
In cases where severe rope wear takes place at one
end of a wire rope, the life of the rope may be
extended by changing round the drum end with the
load end, i.e. turning the rope ‘end for end’ before
deterioration becomes excessive.
5.2 Remove broken wires as they occur by bending backwards and forwards using a pair of pliers until they break deep in the valley between two outer strands. Wear protective clothing, such as overalls, industrial gloves, helmet, eye protectors and safety footwear
during this operation.
Do not shear off the ends of broken wires with
pliers as this will leave an exposed jagged edge, which is likely to damage other wires in the
rope and lead to premature removal of the rope from service. Failure to wear adequate protective clothing could result in injury.
Note: Broken wires are a normal feature of service, more so towards the end of the rope’s life, resulting from bending fatigue and wear. The local break
up of wires may indicate some mechanical fault in
the equipment.
Record the number and position in the rope of any
removed broken wires.
5.3 Do not operate an appliance if for any reason
(e.g. rope diameter, certified breaking force, rope
construction, length or strength and type of rope
termination) the wire rope and its termination is
considered unsuitable for the required duty.
5.4 Do not operate an appliance if the wire rope
fitted has become distorted, been damaged or has
deteriorated to a level such that discard criteria
has been reached or is likely to be reached prior
to normal expected life based on historical
performance data.
Rope distortion is usually a result of mechanical
damage and can significantly reduce rope strength.
5.5 An authorized competent person must examine
the rope in accordance with the appropriate
Regulations.
Slacken the wedge in the socket. Pass the rope
through the socket by an amount equivalent to the
crop length or sample required. Note that the
original bent portion of the rope must not be retained within the wedge socket. Replace the wedge and
pull up the socket. Prepare and cut in accordance with section 4.12. Ensure that the rope tail cannot withdraw
through the socket, see section 4.13.
5.6 Do not carry out any inspection, examination,
dressing / lubrication, adjustment or any other
maintenance of the rope while it is suspending a load,
unless otherwise stated in the OEM’s instruction
manual or other relevant documents.
Do not carry out any inspection or maintenance of the rope if the appliance controls are unattended unless the surrounding area has been isolated or sufficient warning signs have been posted within the immediate vicinity.
If the appliance controls are attended, the authorized person must be able to communicate effectively with the driver or controller of the appliance during the
inspection process.

Only use compatible cleaning fluids which will not
impair the original rope lubricant nor affect the rope
associated equipment.
The use of cleaning fluids (particularly solvent based)
is likely to ‘cut back’ the existing rope lubricant leading to a greater quantity of lubricant accumulating on
the surface of the rope. This may create a hazard in
appliances and machinery which rely on friction
between the rope and the drive sheave (e.g. elevators, friction winders and ski lifts).
5.8 Lubricants selected for in-service dressing must
be compatible with the rope manufacturing lubricant and should be referenced in the OEM’s instruction manual
or other documents approved by the owner of the
appliance. If in doubt, contact Bridon.
Adjust the lengths of ropes in multi-rope systems in
order that equal forces (within approved limits) are
evident.
5.9 Take particular care when applying any in-service lubricant / dressing. Application systems which involve pressure should only be operated by trained and
authorized persons and the operation carried out strictly in accordance with the manufacturer’s instructions.
Most wire ropes should be lubricated at regular intervals
(including cleaning) in order to extend safe performance.
Ensure that any in-service lubricant dressing penetrates into the core of the rope.
Ensure that the in-service lubricant dressing is not
applied excessively so that the amount of lubricant on
the rope will hinder rope examination.
5.11 Damage to, or removal of, component parts
(mechanical or structural) caused by abnormal
contact with wire rope can be hazardous to the safety of the appliance and/or the performance of the rope (e.g. damage to the drum grooving such that spooling is erratic and/or the rope is ‘pulled down’ into underlying layers, which might cause a dangerous condition or, alternatively, cause
localized rope damage at ‘cross-over’ positions, which might then radically affect performance;
loss / removal of wear plates protecting the
structure leading to major structural damage by
cutting and/or failure of the wire rope due to
mechanical severance).
5.12 Following any periodic examination or
routine or special inspection where any corrective
action is taken the Certificate should be updated
and a record made of the defects found, the extent
of the changes and the condition of the rope.
5.13 Apply the following procedures for the selection
and preparation of samples, from new and used
lengths of rope, for the purpose of examination and
testing to destruction.
Check that the rope end, from which the sample will
be taken, is secured by welding or brazing. If not,
select the sample length further away from the rope
end and prepare new servings.

Handle the rope in accordance with the instructions
given in Section 4. Serve the rope using the buried
wire technique and apply a rope clamp or grip as
close to the cut mark as practically possible. Do not
use solder to secure the servings.
Ensure that the sample is kept straight throughout the
whole procedure and ensure that the minimum sample length is 10′ unless otherwise specified.
The rope should be cut with a high speed abrasive
disc cutter or an oxyacetylene torch. Weld the rope
ends of the sample as described in section 4.12, after
which the clamp or grip can be removed.
The identification of the rope must be established and
the sample suitably marked and packed. It is
recommended that the 10′ sample is retained straight
and secured to a wood pallet for transportation.
Failure to comply with these procedures will result in
measured breaking force values which are not truly
representative of the actual strength of the rope.
6.2 If a wire rope is removed from service at a level of
performance substantially different to historically
established performance data and without any obvious
reason(s), contact Bridon for further guidance.

Note: The authorized competent person should also
be familiar with the latest versions of ANSI, ASME or ISO Standards. Other standards and instructions
6.3 Only qualified and experienced personnel, taking the appropriate safety precautions and wearing the
appropriate protective clothing, should be responsible
for removing the wire rope.
Take particular care when removing ropes with
mechanical damage as they may fail abruptly during
the change-out procedure.
Take the utmost care when removing ‘exhausted / failed’ ropes from drums and sheaves as they may be grossly distorted, lively and tightly coiled.
Failure to take adequate precautions could result in injury.
6.4 Store discarded rope in a safe and secure location or compound and ensure that it is suitably marked to identify it as rope which has been removed from service and not to be used again.
6. Wire Rope Discard
covering rope discard may also be applicable. In the case of synthetic sheaves (or synthetic linings), refer
to the OEM’s instruction manual or contact the sheave (or lining) manufacturer for specific discard criteria.
Discarded rope can be a danger (e.g. protruding broken wires, excessive grease / lubricant and rope mass) to
personnel and equipment if not handled correctly and safely during disposal.
6.5 Record the date and reason for discard on the

6 x 7 Classification
Services
Hoists
6 x 7 Classification Wire Ropes give long service in
operating conditions where ropes are dragged along the
ground or over rollers. Larger sheaves and drums (than
those used for more flexible constructions) are required to
avoid breakage from fatigue. 6 x 7 Classification Ropes
contain 6 strands with 3 through 14 wires, no more than
9 of which are outside wires.
In a 6 x 7 rope, the wires are larger than those of other
constructions of the same diameter. Wires of a 6 x 7 are
approximately twice the diameter of outer wires of a
6 x 25 FW rope. The large size of the outer wire gives
the class excellent abrasion resistance—at great sacrifice
of bendability and resistance to fatigue. The standard
6 x 7 rope construction is made with fiber core and right
regular lay.

High strength rotation resistant rope incorporating
Dyform strands—confirmed by Bridon’s “Powercheck” testing of a sample from each production length.
Good resistant to rotation—confirmed by Bridon's unique “twistchecked” type testing program.
Superior bending fatigue life when compared with
conventional multi strand ropes—confirmed by
laboratory testing and extensive field experience.
Excellent resistance to crushing and abrasion resulting from the overall compactness and robustness of the rope and the Dyform strands recommended when
multi-layer spooling is involved.
Optional plastic coating (PI) of IWRC to further extend fatigue life, improved structural stability and resistance to corrosion.

SFP 19 provides:
Fatigue Resistance. Improved fatigue properties are derived
through the combination of the flexible 19 x 19 construction
and die drawn strands. The drawn strand surfaces minimize the
interstrand and interlayer nicking that take place in round
rotation-resistant ropes.
SFP 35 is a rotation-resistant rope of high strength
that can resist block twist in long falls.
Abrasion Resistance. Die drawn ropes provide improved
abrasion resistance as compared with round wire ropes because
of the greater wire and strand bearing surfaces contacting
sheaves and drums.
SFP 35 provides:
Superior Rotation Resistance—the SFP 35 rope is the most
rotation-resistant rope manufactured by WW. Due to its rotation-resistant
properties, SFP 35 may be used with a swivel in both single-part and
multipart reeving.
Resistance to Drum Crushing. SFP 19 wire ropes are resistant
to the effects of drum crushing due to the compacted strands and
smoothness of the rope surface.

SUPER-PAC provides:
Better Resistance to Multi-layer Drum Crushing. SUPER-PAC
dramatically reduces the damage at cross over points on smooth face
drums, such as those found on many boom hoist systems on mobile
cranes. This is achieved by compaction of the strands and the rope,
making a tough but flexible product.
Super Strength. The double compaction process also increases the
minimum breaking strength of standard EIP rope more than 20%.
Other features of 8-PAC include:
Superior Fatigue Resistance. SUPER-PAC is engineered for overall
performance, its wire tensile strength being the key to its superior fatigue
resistant properties. In addition to contribution to SUPER-PAC’s EEEIP
breaking strength, the wire used in the manufacture of SUPER-PAC
remains ductile, minimizing the occurrences of external and internal wire
breaks caused by operating stresses.
Superior Performance. 8-PAC has higher breaking strength and gives
superior performance in difficult hoisting applications compared to
standard 6-strand and 6-strand compacted ropes.
Abrasion Resistance. 8‑PAC compacted strand design provides
improved abrasion resistance as compared to standard 6 and 8 strand
ropes because of the increased wire and strand surfaces contacting
the sheaves and drums.
Application. SUPER-PAC is ideal for all types of boom hoist and
lowering ropes.

The triangular strand shape not only provides better
resistance to crushing, but also offers a greater exposed
surface area for contact with sheaves, drums or underlying
layers of spooled rope. This feature, in connection with
the use of Lang lay construction, distributes the abrasive
wear over a greater number and length of wires.
Superior Resistance to Multi-layer Drum Crushing.
TRIPLE-PAC provides superior resistance to crushing through
its design. Its triple compaction provides a denser cross section,
enabling the rope to withstand the rigors of multilayer spooling.
Damage at the cross over points is also significantly reduced.
In addition, TRIPLE-PAC’s design increases the amount of wire
contact with sheaves and drums, reducing wire rope, drum
and sheave wear.

High Strength. TRIPLE-PAC is designed to provide a nominal

BXL is infused with a specially-engineered polymer,
creating a well-balanced matrix. BXL is recommended
for numerous hoist, marine and logging rope
applications.
BXL provides:
Fatigue Resistance. Improved fatigue resistance is derived
from the cushioning and dampening effect of the polymer on the
wires and strands. BXL also evenly distributes stresses,
which may lead to fatigue breaks.
Abrasion Resistance. The polymer acts as a barrier between
the individual strands, preventing penetration of any adverse material.
BXL distributes and reduces contact stresses between the rope and
sheave, reducing wire rope wear.
Resistance to Multi-layer Drum Crushing. BXL’s smooth profile
evenly distributes crushing pressures from the overlying layers
of rope in multilayer drum winding applications.
Extended Sheave and Drum Service Life. BXL minimizes
corrugation and wear normally associated with standard rope
usage by restricting water and dirt penetration and
eliminating pickup of abrasive materials.

These strengths apply only when a test is conducted with both ends fixed. When in use, the strengths of these ropes may be significantly reduced if one end is free to rotate.
Flex-X® vs. standard rope of similar construction:
Less sheave and drum wear Flex-X 6 users receive
superior performance and increased service life in many
applications compared to the ropes they had previously
employed. When compared to conventional six strand ropes,
Flex-X 6 ropes provide greater surface area and more
steel per given diameter. This increases rope stability and
strength. This results in a longer service life and less
sheave and drum wear.
Flex-X designs reduce drum scrubbing between the lead
line and the previous wrap. The smooth contact creates
less interference, less metal loss and wire deformation.
The increased surface area of Flex-X can be seen in
the comparison of the contact points of a standard
6 x 26WS and Flex-X as shown.

■ More crush resistance than a standard 19 x 7 rope
while providing the same rotation resistance.
■ Higher strength-to-diameter due to compacted wires
in the strands. With increased metallic area, it provides
rope strengths equal to 6 strand XXIP IWRC ropes
of the same diameter.
■ Resistance to bending fatigue due to the uniformity of
the wires within each strand. The strand’s outer surface
is smooth, reducing contact pressures between the rope’s strands and radial pressures as it operates
over sheaves and drums.
■ Exceptional stability due to the higher density strands coupled with the smooth outer surface.
■ Improved handling, operating and spooling
characteristics.
■ Reduced wear to sheaves and drums.

PFV® & Tuf-Kote®
ON PAGES 721 - 723.
General-purpose wire rope that delivers
extra-long service life.
The key to PFV and Tuf-Kote wire rope’s benefits lie in
its exclusive patented fabrication. Standard, lubricated
Macwhyte® and Union® Wire Rope is used in the extrusion
process where the “gaps” (or valleys) between the individual
rope strands are impregnated with a sealing thermoplastic
material. Each strand “valley” in the finished rope is filled
with plastic. The finished rope may have a thin “skin coating” of plastic but this has no significant effect on the outside
diameter of the PFV and Tuf-Kote rope or its serviceability.
Result: PFV and Tuf-Kote wire rope is a balanced
sealed-lubricated wire rope that delivers exceptional
performance and service life on applications that produce
severe operating conditions, such as: haulback lines in
high lead logging systems, saw mill carriage lines,
draglines, towing hawser and drilling lines. And there
is less sheave and drum wear.

Wire Rope Lubricant
Services
Hoists
Wire ropes contain numerous
moving parts which require
lubrication. Each time the rope
bends or flexes, the internal
strands rub together. Whitmore’s
Wire Rope Lubricant coats
these strands to prevent friction
and wear. This results in longer
wire rope life, less downtime
for rope changes and more
production.
Benefits:
■ Prolongs wire rope life—readily penetrates to the
core and lubricates internal strands.
■ Non-tacky—eliminates dirt pick-up and lubricant
sling-off.
■ Guards against rust and corrosion—displaces water
as it penetrates.
■ Extreme load carrying ability—extends wire rope
life and minimizes downtime.
■ Aerosol propellant is non-flammable—safe to use.
Available in a variety of container sizes.
Provides inner strand preservation and lubricity.
Allows for easy visual inspection of the ropes.
Reduces the friction between the strands of the wire rope, thus extending rope life.
Adheres to surface of strands, forming an outer film which provides excellent corrosive protection.
Non-tacky (will not attract dust)
Vitalife® in aerosol form is a regulated dangerous good. See MSDS sheet for shipping instructions.
Vitalife® Bio-Lube has been developed especially for environmentally friendly applications.
Vitalife® 500 has been developed exclusively for
ski lifts and tramways.
Vitalife® 600 has been developed exclusively for
elevator applications.

Whitmore’s Wire Rope Lubricant can be used to lubricate
all sizes of wire rope, as well as chains, leaf springs and
other applications where penetrating oil is needed. It may be
applied by hand or automatic lube system.
Wire
Rope
Vitalife® products are the preferred wire rope lubricants
in the industry because of their ability to penetrate into
wire rope and displace water and contaminants, thus
reducing wear and corrosion throughout the rope.
Whitmore’s Wire Rope Lubricant is easily pumpable at
temperatures down to -25°F (-35°C). Its nondrying
film remains flexible in the most extreme weather conditions,
which eliminates flaking and peeling.

Whitmore’s Wire Rope Lubricant
quickly penetrates to the core.
This ensures that the rope is
lubricated throughout while
providing a non-drying, non-tacky
film on the outside of the rope.
This protects outer strands from corrosion, as well as
lubricating the wire rope drums and sheaves.

Pulling / Splicing Grips
Overhead, Underground,
Commercial Construction, Specialty
Kellems® Wire Rope Grips are made of high strength
galvanized steel strand in a construction of triple, double
and single weave for superior gripping ability. They are
available with or without a rotating barrel, which will help
eliminate twist in the old rope from being transferred to
the new rope.
Flexible or rotating eyes will mate easily with line stringing
swivels for attachment to pulling lines; they have great
strength for trouble free pulling jobs.
Shoulder protectors contain the cable inside the grip and
smooth the passage of the grip over line stringing blocks
or conduit bends; they protect the leading edge of the grip
from abrasion.
The galvanized steel mesh grip provides strength for
secure pulling jobs and a slim profile with little build-up;
it has flexibility to follow cable path.
The multi-weave styles available add strength for big pulling
jobs and provide positive gripping power.
Endless weave allows easy installation onto cable. It has
a snag-free low profile; designed to be reusable tool.

When the tail of a grip is the leading end, the bands are particularly
important to prevent accidental release caused by tripping on
obstructions. A conductor-to-conductor (double-socking) pulling operation
is a good example: where two grips connect two conductors to form
a temporary splice. Bands should be applied to the ends of the grips as
illustrated herein. It is also common practice to tape over the banded
tail area to assure smooth passage through the sheaves. The conductor
should be installed in the grip up to the elbows of the aluminum
shoulders in order to assure full and complete gripping action.

Description
Swivels are essential to the efficiency and safety of any high tension
application. They are particularly important where continuous pulls
develop higher and higher torque levels. Torque is intensified by the
pull resistance of the cable itself and the resistance of the high tension
controlling equipment regulating line sag.
20320048
20320047
Note: In all cases two Punch-Lok Bands should be double wrapped
approximately 1" to 2" from the grip’s tail. Banding is required to ensure
maximum reliability and guard against accidental release.
Ball bearing swivels release torque and prevent it from reaching
dangerous levels that can damage the cable and obstruct the lines
as it passes through sheaves, wheels or blocks.

Repair or replace?
Klein "Chicago" Grips have locking loop handles, standard on most grips
and available on hot-line grips by ordering with spring. The locking feature allows the jaws to be held in an open position for easier placement
on wire or cable. Saves substantial time, makes grip positioning easier
than with wedge or boil-on designs. To lock, open jaws and fold loop
handle toward the side plates.
Never repair any grip. Grip laws can sometimes be replaced if the grip
is returned to Klein, but structural wow or damage cannot be safely
corrected. Grips that are bent, misaligned or otherwise distorted should
be discarded and replaced.
Before each use, check all grips for jaw condition, proper alignment of
jaws and all parts, and possible distortion caused by exceeding safe-load
specifications. Grips should operate smoothly. Spring-loaded grips
should lock open with loop handle in "Down" position and should dose
automatically with loop handle "Up".
Klein "Chicago"® Grips
How to select the
proper grip.
The Klein parallel jaw grip maybe tested by opening and closing the jaws
by hand, exercising proper caution. All parts and rivets which may be
distorted due to exceeding safe load should be checked.
Care should be taken in
choosing grips to assure correct
handling of wire and cable.
Three basic factors determine
the selection of the proper grip
for each specific application:
1. Type of wire or cable.
2. Outside diameter of wire or cable.
3. Maximum safe load required.
Recommended Care and Maintenance
All three of these factors are included in the description of each Klein
grip along with the type of inside jaw contour available. Correct selection
of gripping jaws is essential to avoid damage to wire or cable. In pulling
stranded wire, the jaws should be long enough to take a full lay of cable
to avoid damage to the conductor.
The following guidelines have been established in order to maintain all
grips in good condition:
1. Clean the grip jaws. Use emery cloth or a clean wire brush to periodically clean the surfaces of grip jaws.
Note: Aluminum-strand conductors may have a die-grease coating which can de¬posit on grip jaws. Now aluminum conductors should be wiped clean before grip application.
Grip jaws should be wiped clean of all grease before use.
Be sure to clean grip jaws before and after each use on wire or cable which has been galvanized or otherwise coated.
The tables in this grip section are supplied to assist you in determining
outside diameters and breaking points of the various types and sizes of
wire and cable in general use.
2.
Clean aft working parts. Use Klein's Cinch Cleaner / Degreaser Cat. No. 51101 to clean all joints and moving parts, then apply Cinch Yellow No. 51045.
For our recommendations of the proper grip to meet your needs,
send exact cable description and pulling requirements.
3. Check all parts. Look carefully for distortion or misalignment.
4.
Never repair any grip. If there is ever any question about the
safe condition of any grip, please consult us directly.
Please remember this rule.
Please order grips by description and specifications only.
Actual product may vary from photo.

steel cable, the galvanizing has a tendency to coat the
jaws of any grip, causing the cable to slip. To reduce
the possibility of slippage and damage to the cable, the
jaws of this grip are milled on a curve with a
double “V” contour.

Grip-Cleaning Brush Set
Proper maintenance and field inspection of all grips is necessary
before each use. Check to be sure there is no accumulation of foreign
material in the jaws which might cause slippage. Check mechanical
condition of entire grip. Check grip to be sure it is correct size and type
for the application. Clean and lubricate. Do not lubricate gripping
surfaces of jaws. Check all parts for distortion or misalignment.
Set of four wire-bristle brushes
designed for cleaning Klein
wire- and cable-pulling grips.
Brushes have stiff wire bristles.
Available in round and square
shapes and two lengths for
efficient cleaning of different jaw
configurations. Semi-flexible
steel shafts set into comfortable
wooden handles provide the
necessary reach into grip jaws.

Kellems® Wire Management Products
Pulling / Splicing Grips Cautions & Warnings
Safety and Working Load Factors
For Wire Mesh Grips
CAUTION
It is very important to comply with all of the following
precautions. Failure to do so may result in property damage,
personal injury or death.
The broad application of Kellems grips on a wide variety of
objects requires that adequate safety factors be used to
establish working loads. The approximate breaking strength
of a Kellems grip represents an average calculation based
on data established from actual direct tension testing done
in our engineering laboratories.
1. 2. 3. 4. 5.
6. 7. 8. It is impossible to catalog or guarantee a safety factor suitable
for all applications as operating conditions are never the same.
The tension, diameter, movement, number of objects gripped,
gripping surface, and the attachments used are just some of the
factors which vary with each application. These factors,
together with the effects of abrasion, corrosion, prior use or
abuse and any other variables of a specific application,
must be considered by the user and the grip replaced as
appropriate. Where the conditions of the application
are not well defined or known, or where risk of injury to
persons or property is involved, a greater safety factor
should be utilized.
Under normal conditions, Kellems’ recommended factor of
safety is five for catalog listed pulling grips, and ten for
catalog listed support grips. Any warranty as to quality,
performance or fitness for use of grips is always premised
on the condition that the published breaking strengths
apply only to new, unused grips, and that such products
are properly stored, handled, used, maintained and inspected
by the user at a frequency appropriate for the use and
condition of the grip.
Pulling grips are to be installed by a qualified individual in
accordance with all applicable national and local safety,
electrical and rigging codes.
Ensure that the correct grip is selected for your
specific needs.
Do not use a pulling grip for any application other than
pulling cable.
Thoroughly examine the grip for damage. Do not use a
damaged grip.
Ensure that the recommended work load of the grip
is suitable for the application. Never use grips at their
approximated rated breaking strength. A safety
factor of 5 is recommended for pulling grips.
Do not alter grips in any way. For example, do not modify
pulling eyes, shoulders, fittings or lugs.
Do not attach any type of pulling hardware to any point
on the grip other than the pulling eye. The pulling eye is the only acceptable means of attachment to external hardware.
Always apply 2 bands at 1" and 2" respectively, from the
tail end of the mesh to guard against accidental release of
the grip. Accidental release can occur if an object contracts and pushes against the tail end of the mesh, thereby
expanding and releasing it’s hold.
For complete warning and application
information, see Hubbell Incorporated
at www.hubbell.com
Warnings
WARNING
■
■
■
■
■
Before each use, clean jaw area and inspect grip for
proper operation to avoid slippage.
When used on/near energized lines, ground, insulate,
or isolate grip before pulling.
Do not exceed rated capacity.
Always match proper size and type of grip to application.
Grips are to be used for temporary installation, not
for permanent anchorage.

Boom Pendant Inspection
Boom pendant inspection is vital for
proper use.
4. Inspect the fitting attachments.
Hand spliced: look for slippage in the splice or any tucks that may have pulled out.
Poured zinc or thermo-set resin sockets: look at the base of the sockets for any signs that the wires may
be pulling out of the zinc or thermo-set resin. Look at
the top of the cone for any sign that the zinc or
thermo-set resin is cracked or is chipping or flaking off.
Returned loop swaged: look for any sign that the
sleeve may be cracked, crushed or peeling back.
Look for any sign that the rope may be pulling out
of sleeve.
Flemish eye swaged: look for any sign that the
sleeve may be cracked, crushed or peeling back.
Swaged sockets: look for any signs of a cracked
or bent shank. Look for any sign that the rope may be pulling out of the socket.
5.
Inspect the end fittings: inspect the fittings for any
signs of cracking or distortion. Pay particular attention to the area around the pin holes and along the ears
of open sockets.
Inspect the pin holes for any signs of elongation or excessive wear.
Inspect the socket pins for any signs of bending or
excessive wear.
Note: If any of the above conditions exists, the pendant should
be removed from service and inspected or tested further.
This is intended to be a general guide only. Contact
the manufacturer of the equipment, the pendants and/or
the end fittings to get specific retirement criteria.
Reference to ASME Standard B30.9.

Watch for broken
wires in this area
Slings
Inspect the rope for broken wires—especially near
the end fittings. Even one broken wire near an
end fitting may be a sign that the rope is deteriorating and may be near failure. Any “valley breaks,”
that is, wires that have broken in the valley between
two strands may also be a sign that there is serious vibration fatigue in the core.
Hardware

Lifting
Products
Inspect the outside wires and strands for damaging
rust or abrasive wear caused by loss of lubrication,
or by the rope’s contact with the boom or other
structures on the crane.

Rope
2.
This assembly
must be replaced.
Cordage
Measure the diameter of the rope at several points along the pendant, especially near the end fittings.
Measurements below the rope's nominal diameter may mean that the core is deteriorating, even if the outside wires and strands appear to be in good condition.

Forged from special bar quality carbon steel, suitable
for cold forming.
Hardness controlled by spheroidize annealing.
Swage Socket terminations have an efficiency rating of 100% based on the catalog strength of wire rope.
Stamp for identification after swaging without concern for fractures (as per directions in National
Swaging Brochure).
Before using any National Swage fitting with any other
type lay, construction or grade of wire rope, it is
recommended that the termination be destructive tested
and documented to prove the adequacy of the assembly
to be manufactured.
In accordance with ASME B30.9, all slings terminated
with swage sockets shall be proof loaded.
Note: S-502 Swage Sockets are recommended for use
with 6 x 19 or 6 x 36, IPS or XIP (EIP), XXIP (EEIP), RRL,
FC or IWRC wire rope.

The Nicopress 64-CGMP/Cutter Tool combines
two important functions…cable cutting and oval sleeve
pressing. The 64-CGMP/Cutter Tool eliminates the
handling of two separate tools. Engineered for field
conditions, this tool is made from drop-forged alloy
steel; the working surfaces are heat treated and specially
hardened. Toggle action provides high mechanical
force and results in low cutting effort. Cutting blades can
be reversed for long useful life. This versatile field
and shop tool cuts mechanical cable sizes up
thru 7/32".
Cuts Cable
Slings
The 64-CGMP/Cutter Tool presses Nicopress Oval
Sleeves 1/16" (C), 3/32" (G), 1/8" (M) and 5/32" (P).
In addition, the 1/16" stop sleeve can be pressed
with the C groove.
Very low cutting effort is required to cut mechanical
steel cable up thru 7/32". Hardened cutter blades
surround and support the cable during the cutting action,
which results in round, clean-cut cable ends.
Lifting
Products
Hardware
This tool cuts mechanical steel cable as large as 7/32",
the cutting surfaces surround and support the cable
while it is being cut. There are no frayed cable ends
and cable cuts are clean and round.

Splices made with these tools typically hold
military specification grade aircraft control
cable in tension until the cable breaks. To ensure
good splices, make the proper number of
presses in each sleeve. Applications that require
continuous and frequent sleeve pressing call
for the use of our larger toggle action tools,
or power press equipment.

The impact type wire rope cutters are the original portable
tools invented by Morse-Starrett to cut wire rope. The cutters
are actuated by striking with a hammer, they are easy to
operate and do a superior cutting job with only a few blows
of a hammer. These cutters are precision engineered to
deliver a cut without affecting the original roundness of the
wire rope. The blades and dies are made of the finest tool
steel available, heat treated and ground to close tolerances.
The impact style cutters are available in three sizes and
cutting capacities. The Model 1 has a 3/4" capacity, the
Model 1A a 1-1/16" capacity and the Model 2 has a
1-1/2" capacity. Replacement blades are also available.

The self-contained hydraulic cable cutter is a precisionengineered tool designed to give a clean cut with minimum
effort. Just pump the handle...no outside power is required.
This self-contained portable tool can be easily carried and
is used by contractors, rigging lofts and elevator repairmen.
All three models will operate under water. The Pell
HYDRASHEAR® is recommended by wire rope
manufacturers and used by industries throughout the world.
The blades and die sets are made of the finest tool steel
available, heat treated and ground to close tolerances.
This means a long life for the blades, as well as superior
performance. The hydraulic cutters are available in three
sizes and capacities. The Model W-075 has a 3/4" capacity,
the Model P-1125 a 1-1/8" capacity and the Model
C-1750 has a 1-3/4" capacity.

The power-operated cutters require an external hydraulic
power source for operation. These models can be
activated by any electric, gasoline, hand, battery or air
operated hydraulic pump capable of developing 10,000
PSI and having free flow return through the pressure line.
The pumps are hose-connected to the HYDRASHEAR
body. The power-operated cutters are available in three
sizes and cutting capacities. The Model POC1125 has a
1-1/8" capacity, the Model POC1750 a 1-3/4" capacity
and the Model POC2500 has a 2-1/2" capacity.

Precision Cable Cutters
Swiss Made Felco cutters are recognized around the world
for their precision manufacturing and cutting capabilities.
Lightweight enough for overhead cutting, yet strong enough
for underwater work. Plastic coated handles afford a firm,
comfortable grip. Replacement parts are available from
stock. All cutters are tested before leaving the factory.
Type C-108
Type C-7
Length: 22" / Weight: 4.5 Ibs.
Simple construction with all parts
protected against rust and salt water.
Designed as an indispensable part
of boat equipment. Especially suited
for quick, easy cutting of shrouds, stays,
halyards and other rigging of high-tensile
wire rope or cable up to 5/16" diameter.
Inexpensive insurance for that rare
time when a mast breaks. The C-108
will cut virtually any material, including
steel rods up to 5/16" diameter and
tempered steel spring wires up to
1/4" diameter.
Length: 8" / Weight: 10 oz.
A cable, when crushed or
deformed in cutting, is difficult to
use with fittings. These cable
cutters, with unique triangular
jaws, never leave a frayed end.
Cutters range from the lightweight
Type C-7—Capacity: 3/16"
diameter and smaller.
Type CP Cutters—
For Steel Strapping
and Banding
Type C-112
Length: 8" / Weight: 10 oz.
CP cutters are indispensable for
cutting steel strapping and banding.
They are also especially good for
cutting string, twine, rope, tin and
many other materials with ease.
The red plastic handle is fitted to
the hand to make cutting comfortable.
A thumb catch locks the cutter
when not in use.
Like the C-108, this cutter also has
maximum force transmission, which
applies the maximum leverage just
at the right moment. This, coupled
with Swiss precision blades, make the
C-112 and the C-108 amazingly
easy to use. The C-112 will handle
a maximum capacity of 1/2"
hitensile strands.
Type C-9
Type C-12
Fills the gap between
C-7 and C-12—cuts 1/4"
steel cable. Ideal for
the tool kit.
Length:19" / Weight: 3 Ibs.
Capacity: 3/8" diameter and smaller.
Type C-16
Length: 23" / Weight: 5 lbs.
Capacity: 5/8" diameter and smaller.
Type C-16E (Electrical)
Length: 23" / Weight: 5 lbs.
Cuts ACSR cable up to 3/4".
