| Wire
rope does not spool smoothly on the drum. |
- The winch may be mounted too close to the main sheave,
causing the fleet angle to be more than 1½ degrees.
Check mounting distance and fleet angle. Reposition
winch as required.
- The winch may not be mounted perpendicular to an imaginary
line between the center of the cable drum and the first
sheave.
Refer to "Winch Installation" section of the
service manual.
- Could possibly be using the wrong lay rope. There is a
distinct advantage in applying rope of the proper direction
of lay. When the load is slacked off, the several coils
on the drum will stay closer together and maintain an even
layer. If rope of improper lay is used, the coils will spread
apart each time the load is removed. Then, when winding
is resumed, the rope has a tendency to criss-cross and overlap
on the drum. The result is apt to be a flattened and crushed
rope.
Consult wire rope manufacturer for recommendation
of wire rope that best suits your application.
- The winch may have been overloaded, causing permanent
set in the wire rope.
Replace wire rope and conduct operator/rigger
training as required.
