TIPS FOR EXTENDING THE LIFE OF
YOUR WINCH
1. KEEP A TIGHTLY WOUND WIRE
ROPE DRUM. Do not allow the
wire rope to become loosely
wound. A loosely-wound spool
allows a wire rope under load to
work its way down into the layers
of wire rope on the drum. When
this happens, the wire rope may
become wedged within the body
of the windings damaging the
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.
2. DO NOT ALLOW WINCH MOTOR
TO OVERHEAT. Remember, the
winch is for intermittent use only.
During long or heavy pulls the
motor will get hot. At 1,000 lb.
(454 kg) allow motor to cool after
20 seconds of "On" time. At loads
less than 500 lb. (227 kg) allow to
cool after 2 minutes of "On" time.
3. USE A PULLEY BLOCK FOR HEAVY
LOADS. To maximize winch and
wire rope life, use a pulley block
to double line heavier loads
(Figure 17).

4. The pull required to start a load
moving is often much greater
than the pull required to keep it
moving. AVOID FREQUENT STOPS
AND STARTS during pull.
5. PREVENT KINKS BEFORE THEY
OCCUR.

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 per-
manently damaged 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.
6. EQUIPPING THE WINCH WITH A
ROLLER FAIRLEAD will substantially
reduce wear on the wire rope
during angle pulls (Figure 19).
The rollers eliminate heavy rub-
bing and abrasion to the wire rope.
