10. With the wire rope tight, slowly
wind it in, observing both the
work and the drum. Inspect
the hook-up points for slippage
before continuing the lift or pull.
Be sure the wire rope strands
do not cross wrap or criss-cross
on the drum. Observe the path
the work must travel for snags
or obstructions which could stall
the movement and overload the
wire rope.
11. Once the work is in the desired
position, apply the towed
vehicles parking brake or use
blocks or tie the work down
if there is any question about
stability. Slowly reduce the wire
rope tension. After enough wire
rope has been unwound, you
may remove the hookup.
12. Now slowly retrieve the wire
rope, carefully winding the wire
rope onto the drum. Many
operators take this opportunity
to do a visual inspection.
Don’t stress the wire rope by
over retrieving or tightening
and exceeding the working
limit. Over stressing the wire
rope beyond its working limit
can cause damage resulting
in premature wire rope
failure.
