4-7. OPERATION OF
FRONT WINCH.
a. General. Any of the 5-ton 6 x 6 trucks covered in this manual can be equipped
with a front winch. Some of the trucks may also have a level wind device with a cable
tensioner joined to the winch. The front winch is mounted on the front of the truck
on support brackets joined to the left and right side rail extensions. The level wind
devices and tensioner are mounted on the winch. Movement of cable under tension
over the level wind sheave causes the sheave trolley to move from side to side and wind
the cable in layers. Power to drive the winch drum is supplied through a propellor
shaft extending from a power takeoff mounted on the transmission. The control for
the power takeoff is located in the driver's compartment. The winch has an automatic
safety brake to hold the winch load when the power takeoff is shifted. The winch
load capacity is 20,000 pounds with one cable layer on the drum, the capacity be-
comes less with each additional layer of cable on the drum . Refer to Vehicle Re-
covery Operations, FM 2022.
