FRONT AUXILIARY WINCH:
The front auxiliary winch is mounted to the front bumper and is controlled from the operator
compartment. The winch has 125’ (38 m) of 9/16” (14 mm)-6x36 EIP-RRL-IWRC wire rope
with a 33,600-pound (150 kN) minimum breaking force and a 5-ton (4.5-metric ton) rated
hook. The winch is capable of pulling 20,000 pounds (6800 kg) on the bare drum. The
winch can pull 13,400 pounds (6100 kg) on the 4 th layer. Do not exceed the working
strength of the hook and rope. Limit pulls to 10,000 pounds (4.5 metric ton).
Included with this option is a pivoting roller guide and a shut-off limit switch. The switch is
designed to block any further pulling-in of the rope, once the hook nearly reaches the
rollers. Paying-out the rope will not be affected. A pivot link is provided above the winch
mounting to store the hook while not in use.
The front auxiliary winch is designed for the following uses:
1. As a tag line for restraining loads on the boom load line during pick-and-carry operation.
2. To drag loads on the ground to a position where they may be safely lifted with the
boom.
3. To pull the crane out of mud or other obstacles.
4. To pull a smaller vehicle that is stuck.
W A R N I N G
The front winch is not designed for lifting personnel or loads. Observe the following
safety rules:
1. Never lift or carry personnel with the winch and wire rope.
2. Do not allow anyone to stand near or under the load being moved.
3. Be sure the cable is securely anchored in the drum and that at least 5 wraps of rope
remain on the drum to insure against the rope pulling out of its anchor.
4. Stand clear of a loaded winch cable. If it breaks, it can be very dangerous.
5. Keep hands clear of the winch and any sheaves that the cable passes over when the
winch is being operated.
6. Do not over-stow the hook into the roller guide. This may damage the hook, rope, or
the roller guide
7. Do not use the drivetrain to pull a load that is too heavy for the winch to pull. The
drawbar pull of the IC-400 can easily exceed the working strength of a single part of
line for the front winch.
