2. Always inspect your winch cable before each use. Inspect for worn or kinked
winch cable.
A kinked winch cable made of wire rope is shown at
right. Even after being “straightened out,” this cable
has already been permanently and severely damaged.
Promptly discontinue use of a winch cable in this
condition.
A kinked winch cable made of wire rope that has been
“straightened out” is shown at right. Even though it
may look usable, the cable has been permanently and
severely damaged. It can no longer transmit the load
that it could prior to kinking. Promptly discontinue use
of a winch cable in this condition.
A winch cable made of synthetic rope should be
inspected for signs of fraying. Replace the cable if
fraying is observed (shown at right). Promptly
discontinue use of a winch cable in this condition.
Also replace the winch cable if there are fused or melted fibers. Such an area
of the synthetic rope will be stiff and appear smooth or glazed. Promptly
discontinue use of a winch cable in this condition.
SHOCK LOADING
WARNING
Your winch cable is very strong but it is NOT designed for dynamic, or “shock”
loading. Shock loading may tension a winch cable beyond its strength and
cause the cable to break. The end of a broken winch cable under such high
loading can cause SEVERE INJURY or DEATH to you and other bystanders.
Winch cables are designed to NOT absorb energy. This is true of both wire-rope
and synthetic-rope winch cables.
1. Never attempt to “jerk” a load with the winch. For example, never take up
slack in the winch cable by moving the winching vehicle in an attempt to
move an object. This is a dangerous practice. It generates high winch cable
loads that may exceed the strength of the cable. Even a slowly moving
vehicle can create large shock loads in a winch cable.
WARNING
SEVERE INJURY or DEATH can result from a broken winch cable.
2. Never quickly turn the winch ON and OFF repeatedly (“jogging”). This puts
extra load on the winch, winch cable, and generates excessive heat from the
motor. This is a form of shock loading.
