The hoist winch is mounted in the winch compartment and is gear-driven by a hydraulic motor. The winch is capable of hoisting
a maximum load of 50,000 lb (22,680 kg) with a four-part line, using a 5/8-in. (15.88-mm) steel cable. The hoist winch is wound
with 200 ft (61.0 m) of this steel cable.
The hoisting boom is a tubular, modified A-frame, and is pivot-mounted to the top front of the vehicle. The boom is raised or
lowered by two hydraulically operated boom cylinders. In operating position, the boom is supported by a stayline cable secured
to crankarms located at the rear of the hull. The crankarms control the live-boom movement by means of hydraulically operated
stayline cylinders. In lowered position, the boom is secured on the boom support assembly by a boom travel lock. The hoisting
boom is used in conjunction with the hoist winch.
