 TM 55-1905-223-10
winch assembly to the bow ramp chain. These assemblies are wire rope, turnbuckles, stud chain, rope
sheave, chain stopper, wildcat sheave, ramplocking device and wire rope glands port and starboard. The
bow ramp is raised and lowered by the split-drum, hydraulic winch via wire rope. The drum handles two
wire ropes, one to control each side of the ramp. Wire rope is fed to the forecastle deck through wire
rope glands and rigged to chains by turnbuckles. The chain is led through chain stoppers to a chain
sheave. The winch is remotely controlled from three locations: pilothouse console, forecastle deck and at
the winch assembly. The pilothouse console control panel has a power on/off switch. When operating
from the pilothouse console, the other two control stations are inoperative.
1-22. Stem Anchor Winch System. The stern anchor winch system provides payout and haulback of
the stern anchor. The first wrap speed of the winch is 35 feet per minute at high speed and 17 feet per
minute at low speed. The system consists of a winch assembly, hydraulic power pack, Danforth anchor,
anchor chain assembly and deck equipment. Control of the stern anchor winch is provided by a control
panel on the 01 level aft bulkhead, adjacent to the winch.
a. Winch Assembly. The winch assembly is mounted to its foundation on the aft 01 level center
line of the ship. The winch spool is mounted directly on the shaft and is free to rotate on the shaft. Drive
is applied by means of a manually operated, four-jaw, sliding clutch. The clutch lever can be locked in
either the engaged or disengaged position. The mechanical brake is manually operated by a handwheel.
A lever operated dog, which engages the spool, mechanically locks the winch when not in operation. A
level wind provides smooth laying of the wire rope on the spool.
b. Hydraulic Power Pack. The hydraulic power pack assembly consists of a hydraulic pump
driven by an electric motor mounted on the hydraulic fluid reservoir located in steering gear room. The
pump feeds a directional control valve that controls payout, haulback and neutral operation of the winch
assembly.
c. Hydraulic Motor/Failsafe Brake Assembly. Hydraulic fluid, under pressure from the power
pack, powers the hydraulic motor. The motor is coupled to the gear box on the winch via an automatic
failsafe brake. The brake is spring loaded for application and hydraulic pressure is required for release.
Any function which reduces hydraulic pressure below the release pressure of the failsafe brake will cause
brake application.
food preparation, food service, waste disposal, sanitation and galley exhaust and fire protection. Chilled
and frozen food storage units are freestanding refrigeration units. Food preparation units are
freestanding steam kettle, ranges, microwave ovens, fryers and associated equipment. Food service
