MAINTENANCE & USE
TIPS FOR EXTENDING THE LIFE OF YOUR WINCH
1.
Note
: Installing the wire rope is not included in the running-in
period. Check tightness of all mounting bolts after running-in
period.
2.
Keep a tightly wound rope drum
. Do not allow the windings
on the drum to become loosely wound. A loosely wound spool
allows a rope under load to work its way down into the layers of
the wire rope on the drum. When this happens, the lower layers
become damaged and the rope may become wedged within the
body of the windings. To prevent this problem, keep tension on
the rope at all times. A good practise is to rewind the rope under
tension after each use.
3.
Prevent kinks before they occur
.
a) This is a start of a kink. At this
time, the rope should be
straightened.
b) The rope was pulled and the
loop has tightened to a kink. The
rope is now permanently
damaged.
c) The result of kinking is that
each strand pulls a different
amount causing the strands under
greatest tension to break and
reduce load capacity of the wire
rope.
4.
Use a snatch block for heavy loads
. To keep wear to a
minimum, use a snatch block to double line heavy loads. Double
lining reduces the work required of the gears by one half which
in turn reduces wear.
5. The pull required to start a load moving is often much greater
than the load to keep it moving. Try to avoid stopping and
starting during a pull.
