wire rope. To prevent this prob-
lem, keep the wire rope tightly
and evenly wound on the drum
at all times. A good practice is to
rewind the wire rope under ten-
sion after each use. One way to
do this is to attach the hook to a
small load and winch that load to
rewind rope.
2. To maximize winch and wire rope
life, use pulley block to double
line heavier loads.
3. PREVENT KINKS BEFORE THEY
OCCUR. (See Figure 11.)

a. This is the start of a kink. At this
time, the wire rope should be
straightened.
b. The wire rope was pulled and the
loop has tightened to a kink. The
wire rope is now permanently dam-
aged and must be replaced.
c. Kinking causes the wire strands
under the greatest tension to break
and thus reduces the load capacity
of the wire rope. The wire rope
must be replaced.

LUBRICATION
The winch is permanently lubri-
cated. There may be grease leakage
out of winch, especially during first
few operations. This is normal and
it is not necessary to grease or oil
any internal part of winch at any
time.
Periodically lightly lubricate wire
rope with penetration oil and wipe
off excess.
