powered vehicle with a main transmission, drive axles,
and a hydraulic craning circuit. The hydraulic craning
circuit consists of a hydraulic pump and motors, valves,
cylinders, piping, and a superstructure that revolves
360 degrees and can lift and move loads from one
location to another. A 24-volt electrical circuit provides
power for starting, lighting, instrumentation, and
electrohydraulics. The crane's primary purpose is to
remove and replace aircraft components in support of
scheduled and unscheduled maintenance. This includes
engines, transmissions, propellers, engine modules,
and rotor blades.
Forklift Truck
The forklift truck (fig. 9-13) is a cantilever-type
industrial truck, either gasoline, diesel (shipboard use),
or electrically operated, and is used in the handling and
lifting of palletized unit loads. It contains vertical
uprights and an elevator backplate equipped with two
or more forks of sufficient length and thickness for
lifting pallets. The forklift truck is probably the most
widely used power-driven piece of material-handling
equipment for palletized loads aboard ship and in Navy
industrial supply warehouses. When not on a hard
surface, a forklift truck should have pneumatic tires to
operate efficiently. Public works maintains forklifts on
shore stations. Aboard carriers, the support equipment
division of AIMD performs the maintenance.
Flight Deck Scrubber
The fight deck scrubber (fig. 9-14) is designed to
spray a cleaning solution onto the flight and hangar
decks, scrub the deck, and recover the residual solution
and debris for disposal. It consists of the debris hopper
housing, two opposed rotation cylindrical brushes, a
solution and recovery tank, and a vacuum recovery
system and rear squeegee. Those are mounted on a
driver-operated, four-cylinder, two-wheel drive, diesel
engine power drive train. The purpose of having flight
deck scrubbers aboard ship is to achieve and maintain a
high degree of deck cleanliness, which contributes to a
reduction of aircraft engine Foreign Object Damage
(FOD) and provides better traction, thereby improving
personal safety during flight operations.
