FRONT AUXILIARY WINCH:
The front auxiliary winch is mounted behind the front bumper and is controlled from the
operator compartment. The winch has 125’ (38 m) of ½” (12 mm)-6x36 EIP-RRL-IWRC wire
rope with a 26,600- pound (118 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).
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 drive train to pull a load that is too heavy for the winch to pull. The
drawbar pull of the RT-400 can easily exceed the working strength of a single part of line
for the front winch.
