CARGO HANDLING SYSTEM
14-1
DESCRIPTION
The cargo handling system consists of a
hydraulically-operated winch and cable, a cable cutter,
tackle blocks, and a remote-control grip and safety
harness. Stowage bags in the heater compartment are
provided for the cable cutter and tackle blocks when not
in use. System power and control is provided through
various hydraulic valves and electrical switches and
receptacles.
The heart of the cargo handling system is the winch,
mounted to the floor of the heater compartment at
the right forward corner of the cabin. It is powered by
hydraulic pressure from the utility hydraulic system.
By changing cable routing, the winch can be used to
perform several different functions:
Loading cargo into the cabin through the open cargo
door.
Carrying or bringing on board cargo through the open
rescue hatch while in the air.
Personnel rescue operations.
Parachute static line retrieval.
Refer to TM 55-1520-240-10 for information on setting
up the system to perform these functions.
The winch has 150 feet of 1/4 inch steel cable. It has
a 3,000 pound load capacity at a reel-in speed of 20
feet per minute for cargo loading through the cargo
door. For hoisting operations through the rescue hatch,
it can lift 600 pounds at a reel-in speed of 100 feet per
minute. For cargo loading, the effective winch capacity
can be increased by routing the cable through the cable
blocks as described in TM 55-1520-240-10.
The winch system can be operated from either the
cockpit or the cabin. Cockpit operation is by the HOIST
panel on the overhead console. Cabin operation is by
a control grip that can be plugged into an operator’s
panel at sta 320 or receptacles at sta 95 or 502. If power
is lost during operation, a winch-mounted brake will
automatically lock the cable. During rescue operations,
the cable is routed through a cable cutter that is plugged
into a receptacle above the rescue hatch. During cargo
operation, the cable cutter is stowed in the stowage
container and connected to a stowage receptacle in the
heater compartment at sta 95.
