REDUCED VOLUME:
The rope can get smaller because of abrasion and cyclic tension wear. If the rope volume is
reduced by 50%, the rope shall be retired. For a 12 mm diameter rope, that means that a rope
with a circumference of
19 mm shall be retired.
Circumference
measurement is easier
than trying to measure
the diameter.
MELTED OR GLAZED FIBERS:
The friction of the rope on the capstan drum generates
heat. If the rope is subject to high friction heat for a long
period
– for example when the load is greater than the
winch capacity
– it can get damaged very quickly.
If the rope shows fused fibers, visibly charred and melted
fibers, yarns and/or strands, is extremely stiff and is
unchanged by flexing, it shall be retired.
DISCOLORATION/DEGRADATION:
Chemical contamination can cause fused fibers, brittle fibers and stiffness. Retire the rope.
INCONSISTENT DIAMETER:
Shock loading or broken internal strands can cause flat
areas or lumps and bumps on the rope. Retire the rope.
IF YOU ARE IN DOUBT OF THE ROPE
FITNESS
– RETIRE THE ROPE!
