This catalogue is designed to provide a non-technical guide to the selection of a suitable wire rope for
various applications. Technical information is restricted to weights and breaking loads and a few formulae. Constructions and sizes shown here are those
commonly available and used in New Zealand but
there are many others and enquiries for special applications should be directed to your nearest Cookes
branch.
Wire Rope is a machine of many working parts and
like most machines it must be made right, selected
right for the application and used correctly in that
application. Like many machines, there is a great
variety of types of wire rope, each with different properties to suit it’s intended use. The internal combustion engine used to power a racing car is quite different to the one powering a large truck although they
both may produce the same horsepower. Like many
machines it is impossible to combine the advantages
of each type into one single machine. The high horsepower and low weight of a racing engine would be
great in a truck. The high fuel cost and short life would
not. The same with wire rope, the attributes that make
one construction eminently suitable for one application could well be a total disaster in another.

WIRE ROPE DESIGN & CONSTRUCTION
Wire ropes are composed of independent parts - wires,
strands and cores - that interact with each other during service.
Wire rope engineers design those parts in different
steel grades, finishes and a variety of constructions
to attain the best balance of strength, abrasion resistance, crush resistance, bending fatigue resistance and
corrosion resistance for each application.
To select the best wire rope for each application, one
must know the required performance characteristics
for the job and enough about wire rope design to select the optimum combination of wire rope properties.
The following information is provided as a basic
guide. Our expert in house staff and field service specialists are available to provide more specific recommendations.

COOKES
The three attributes of a wire rope to consider are:
(1) Strength.
(2) Flexibility.
(3) Robustness.
In all dynamic rope applications (as opposed to static
applications such as guy wires etc.) the choice is invariably a compromise.
Strength can be increased by increasing the diameter
of the wire rope and/or increasing the tensile strength
of the individual wires and/or increasing the cross
sectional steel content (by decreasing the air voids
between the wires) and/or using a steel core construction.
Flexibility can be increased by using more wires of a
smaller diameter and/or decreasing the tensile
strength of the individual wires and/or using a fibre
core.
Robustness, or resistance to physical damage, can
be increased by using fewer wires of a larger diameter and/or using a steel core and/or by increasing
the steel area exposed to sources of external damage. Coatings such as galvanizing or others can be
applied to protect against corrosion.
11
COOKES
In almost all cases improving one attribute distracts from another. In addition the wire rope’s workplace is rarely ideal. Apart from the environment (dirt,
dust, moisture and chemicals), the equipment to
which the rope is fitted is rarely ideal and another set
of compromises must be decided on. For example all
wire rope suffers from being bent and the smaller the
bend radius the shorter the rope life. For a 26mm
wire rope to escape bend fatigue the winch drum or
block sheaves over which it runs would need a minimum diameter of over 1.5 metres. This is clearly
impractical in many applications, and unnecessary if
bend fatigue does not cause the ultimate demise of
the rope.

STRAND CONSTRUCTIONS.
Strands are designed with various combinations of
wires and wire sizes to produce the desired resistance
to fatigue and abrasion. Generally, a small number
of large wires will be more abrasion resistant and
less fatigue resistant than a large number of small
wires.
14
Single
Size
The basic strand has wires
of the same size wound
around a centre.
Seale
Large outer wires with the
same number of small inner
wires around a core wire.
Provides excellent abrasion
resistance but less fatigue
resistance. When used with
an IWRC, it offers excellent
crush resistance over
drums.
Filler
Wire
Small wires fill spaces
between large wires to
produce crush resistance
and a good balance of
strength, flexibility and
resistance to abrasion

Lang Lay
Wires in strands
and strands of rope
wind the same
direction (right lay
shown). Increased resistance to abrasion, greater
flexibility and fatigue resistance than regular lay,
will kink and untwist.
Right Lay
Strands wound to

FINISH
Bright finish is suitable for most applications. Galvanized finish is available for corrosive environments.
Plastic jacketing is also available on some constructions.
WIRE GRADES
The most common steel wire grades are: 1420-1770
N/mm², and 1860N/mm². Stainless steels and other
special grades are provided for special applications.
Most wire ropes are made with round wires. Both
triangular and shaped wires are also used for special
constructions.
Generally, the higher the strength of the wire, the
lower it’s ductility will be.

While there is a possibility, there is little likelihood
that an application can be found for which there is a
precisely suitable wire rope.
18
COOKES
As with all engineering design proplems, feasible
solutions demand compromise to some degree. At
times is becomes neccessary to settle for less than
optimum resistance to abrasion in order to obtain the
maximum flexibility: the latter being a more important requirement for a given job. A typical example
of this kind of trade-off would be in selecting a highly
flexible rope on an overhead crane. Conversly, in a
haulage installation, a rope with greater resistance to
abrasion would be chosen despite the fact that such
ropes are markedly less flexible.
Two compelling factors that govern most decisions
as to the selection of a wire rope are abrasion resistance and resistance to bending fatigue. Striking a
proper balance with respect to these two important
characteristics demands judgement of a very high
order. A graphic presentation of just such comparison of qualities between the most widely used rope
constructions and others is given by means of an Xchart.
Referring to this chart when selecting a rope, the
midpoint (at the X) comes close to an even balance
between abrasion resistance and resistance to bending fatigue. Reading up or down along either leg of
the X, the inverse relationship becomes more apparent as one quality increases and the other decreases.

EFFECT OF SHEAVE SIZE
Wire Ropes are Manufactured in a great variety of
constructions to meet the varying demands of wire
rope usage. Where abrasion is an important factor,
the rope must be made of a coarse construction containing relatively large wires. In other cases, the great
amount of bending to which a rope is subjected is
more important. Here, a more flexible construction,
containing many relatively small wires, is required.
In either case, however, if the rope operates over inadequate size sheaves, the severe bending stresses
imposed will cause the wires to break from fatigue,
even though actual wear is slight. The smaller the
diameter of the sheave, the sooner these fatigue breaks
will occur and the shorter rope life becomes.
Another undesirable effect of small sheaves is accelerated wear of both rope and sheave groove. The pressure per unit of rope on sheave for a given load is
inversely proportional to the size of the sheave. In
other words the smaller the sheave the greater the
rope pressure per unit area on the groove. Using the
proper diameter sheave for the size and construction
of rope can obviously prolong both sheave and rope
life.
Sheave diameter can also influence rope strength.
When a wire rope is bent around a sheave, there is a
loss of effective strength.
21
COOKES
This is due to the inability of the individual strands
and wires to adjust themselves entirely to their
changed position. Tests show that rope strength efficiency decreases to a marked degree as the sheave
diameter is reduced with with respect to the diameter of the rope.
Therefore, it is evident that a definite relationship
exists between rope service and sheave size. As a
guide to rope users, wire rope manufacturers have
established standards for sheave sizes to be used with
various rope constructions. To secure the most economical service, it is important that the suggested
size of sheaves given on the following page be used.
As a rope is run through a groove, both become
smaller. A used groove can be too small for a new
rope, thus accelerating rope wear. A compromise
between rope life and machining frequency must be
made.
Grooves should have an arc of contact with the wire
rope between 135 and 150 degrees. They should be
tapered to permit the rope to enter and leave the
groove smoothly. Field inspection groove gauges are
made to the nominal diameter of the rope plus 1/2 of
the allowable rope oversize tolerance. When the
gauge fits perfectly, the groove is
at the minimum permissible contour

DRUM WINDING
It is very important to have a rope wind evenly
and tightly on a smooth drum. Due to lay direction
and tension, rope has a tendency to rotate or roll as it
approaches a winch drum. This characteristic is used
to advantage by establishing the winding direction
and dead end location so the rope will rotate in the
direction of the preceding wrap. Tightly packed wraps
on the all-important first layer will ensure proper
winding for additional layers.
If the drum attachment and direction of wraps
are not correctly selected, the first layer of rope will
not wind evenly or tightly, causing the second layer
to pinch down between the wraps of the first layer.
The resultant uneven winding will become worse with
each succeeding layer and result in abnormal scuffing and abrasion. If there are sufficient layers the rope
will pile up and “fall over” on itself with disastrous
results.
The hand rule is a convenient way to check
the correct lay for an installation. The extended thumb
points to the flange to which the rope is terminated
while the extended forefinger represents the rope
leaving the drum. A palm up hand represents
underwind and palm down overwind. If the right hand
meets the conditions, use right hand lay rope and vice
versa.

FLEET ANGLE
Excessive fleet angles can cause serious
damage to wire rope, sheaves and grooved drums.
Severe scuffing results when rope wears against
groove walls, grinding them down causing the rope
to become bruised and crushed.

Angle
Fleet angles on equipment should preferably
be kept between 1° and

drums or 4° for grooved
drums. To ensure the
rope crossing back and
starting the second layer
properly without
assistance the fleet
angle should not be less
than 1°.
The fleet angle is that
angle between the
centre line of the first
fixed sheave and the
centre line of the rope
leading to the drum.

MULTIPLE PULLEY SYSTEMS
Under static conditions the tension in each
part of a rope in a multi-reeved system will be the
total load to be lifted divided by the number of
parts supporting the load. When the load is raised it
is necessary to take into account forces required to
overcome friction in the sheave bearings and the
resistance to bending of the rope as it passes over
the sheave. These additional forces are cumulative
and vary with the type of bearing and the sheave
tread:rope diameter ratio.

SAFE WORKING LOADS
The safe working load (SWL) of a wire rope
or a sling made from it is calculated by dividing
the particular wire rope’s minimum breaking load
(MBL) by the safety factor to be used. This safety
factor depends on the application and may be
determined by legislation or other codes of practice. A common safety factor is 5:1 which means
the SWL of the rope is 1/5th of it’s MBL. Where
the load is evenly supported by more than one
length of rope the SWL can be increased as shown:
Load carried
on two parts
at 90°
= SWL x 1.4
Load carried
on two parts
= SWL x .8
Load carried
equally on two parts
at 30º = SWL x 2
at 60º = SWL x 1.8
at 90º = SWL x 1.4
at 120º = SWL x 1
Load carried
on four parts
at 90°
= SWL x 2.1
29
COOKES
Incorrect installation or handling prior to installation can damage a wire rope and cause failure
before it is even put to work. Care must be taken to
avoid putting a kink in the rope and thus permanently
damaging it. DO NOT lie the coil on it’s side or the
reel on it’s flange and lift the wraps off the top! The
following illustrations demonstrate correct methods:
30
COOKES
31
COOKES
Ensure that wire rope always passes around
winch drums and sheaves in the same direction (always clockwise or always anticlockwise) and ensure
that the rope is loaded to equipment in the same direction as supplied i.e. top of reel (or coil) to top of
winch drum or bottom to bottom, never top to bottom or vice versa:
