Selection
Rope selection involves the evaluation of a number of factors e.g. safety, cost, type of
fittings required to carry out a job safely.
Further consideration for rope selection:Safety Factor
A large diameter rope will outlast a smaller one because it will be used at a lower
percentage of its break strength, therefore there is less chance of the rope being over
stressed and this will equate to a longer working life.
The Australian Fibre Rope Standard AS4142:1 - 1993 recommends minimum safety
factors for ropes in a variety of applications. For rope slings it is 6:1 (i.e. rope subject to
occasional flexing or twisting e.g. ropes in constructed articles such as slings, tow ropes
etc).
Donaghys publish break load charts and other technical brochures for all products and are
available to the user on request.
Working Load Percentage
When used under normal conditions the work load percentage is 20% of published tensile.
This does not cover variables such as shock or sustained loads, nor with life, limb and
property threatening activities. In such cases lower working loads must be used.
Safety
Safety is freedom from damage or injury to life, limb and property. Safety always centres
around risk reduction which must always be considered around the conditions of use.
The key to risk management is identifying the basic safe use requirements for your specific
job e.g. safe working load required, appropriate splicing to line, with bearing surface
protection and or steel fittings.
Abrasion
Donaghys Ocean12 & Winchline products have a very high abrasion resistant coating,
however contact with sharp edges and unpolished or corroded steel surfaces should be
avoided to extend the life of the line. The fitting of heavy duty Polyester tubed webbing eye
protection to the bearing point is recommended, or alternatively, a metal steel thimble.

Ph: 1300 977 577 | www.lifting.com.au
Shock loads
Shockloading must be avoided at all times. Any sudden load exceeding safe working load
of the line by more than 10% is considered a shock load. The memory effect of being
overloaded will be retained by the line and therefore the line may fail at a later time, even
though the load is within the original tensile range.
Elongation and Backlash
Low elongation (5- 6% at break), combined with a low weight, gives a low energy storage.
If the line breaks the failure is often sequential, releasing the energy in steps, further
reducing the risk of backlash. Notwithstanding this, precautions should always be taken
when lines are put under high strain. Never stand in direct line of any rope working under
load.
Storage
Always keep lines as clean and dry as possible. Store away from heat sources and
chemical contaminants, out of direct sunlight. Never store on concrete or dirt floors.
Temperature
Synthetic fibres can be damaged by heat generated through friction or the environment.
Donaghys provide temperature resistances for all fibres, which vary significantly, and
these should be considered in all applications. Friction generated heat can be seen in the
glazed or melted fibres of the rope. Common causes can be non-rotating sheaves, ropes
rubbing against themselves external heat sources or overloading. It is imperative to
choose the correct fibre and construction of rope that suits the application. Contact your
Donaghys representative for the appropriate advice.
Inspection and Retirement
Inspect after each use. Feel along the full length of line or grommet, removing any foreign
matter penetrating the fibres or strands. Also look for broken or cut strands, excessive fibre
abrasion, glossy or glazed areas, inconsistent diameter measurements and other
anomalies.
Document the lines overall condition and load history to assess if retirement and
replacement is required.

Visual Indicators - Example
New Rope Line in Strop form,
showing original bulk and coating
Used Rope
When a rope line is first put into service, the outer filaments will quickly "feather" (fuzz up).
This is a result of surface filaments breaking, this roughened surface actually forms a
protective cushion and shield for the fibres below. This condition should stabilise, not
progress.
If on inspection a rope line is assessed to have lost 20% of the original fibre volume, then it
should be assumed that the rope line has lost 20% of its original tensile as a result of
abrasion. At 25%, volume loss from abrasion the rope line should be replaced/retired.
Internal Inspection
This can be determined by pulling
one strand away from the others,
looking for powdered or broken
fibre filaments.
Compression
When the rope exhibits fibre set from compression a
slight sheen is visible, this is not a permanent
condition and can be eliminated by flexing the rope.

Ph: 1300 977 577 | www.lifting.com.au
Melting and Abrasion
Melting and abrasion are caused by excessive
heat which can melt and fuse the fibres.
This area is extremely stiff, unlike fibre
compression this damage cannot be mitigated by
flexing the rope. The melted or glazed areas must
be cut out of the rope and respliced or retired.
UHMwPE Ropes with Jackets and
Inspection and Retirement Criteria
Mongoose Heavy Duty Recovery Tow Strops and UHMwPE core with Jacket Ropes are
Core Dependant Lines. This means the core is the strength member and carries the total
load. The jacket is an abrasion resistant cover designed to protect the core and can be of
many fibres or combination of fibres; however the most economic and common is of High
Tenacity Polyester.
Inspection of the jacket will provide valuable information in determining ongoing usage or
retirement. The outer jacket can sustain wear and damage without compromise to the load
bearing core, however if sections of jacket expose the core, via broken strands etc, careful
inspection is required. If during inspection, cut strands or section of significant damage is
detected then decommission the rope for suitable repairs that will continue
uncompromised protection of the core. If exposed areas have allowed damage to the core,
then the rope must be retired.
Mongoose Strops are protected with machine braided, urethane coated jackets and heavy
eye protections. This protects the integrity of the core to ensure long life and reliable
performance whilst retaining a high degree of flexibility.

IT IS RECOMMENDED YOUR STROP BE RETIRED IF: Melting and Abrasion is evident on the strops body and including fused fibres,
visible charring and where jacket fibres expose core and visible abrasion/damage is
seen. Probable cause is exposure to excessive heat, shock or sustained load.
 Discolouration on strop body is noticeable along with fused, stiff or brittle fibres
extending into the core. Probable cause is exposure to chemical contamination.
 The outer jacket can sustain wear and damage without compromise to the load
bearing core, however if sections of jacket expose the core, via broken strands etc,
careful inspection is required. Fusion of jacket fibres may extend to core.
 Inspection of the strops body reveals inconsistency in Diameter, Lumps/Bumps/Flat
Areas with no external visible damage to jacket is probable indication of internal
damage IE Shock Loaded, Broken Internal Strand/s
