six-wheel, self-adjusting air/hydraulic brake system
incorporated. Rear and mid dc electric drive motors
provide power for crane travel, while a separate dc
electric motor provides power to the main hoist control
or boom luff control. The crane has a maximum lift
capability of 70,000 pounds and can be operated from
the cab or by a remote pendant control.
The crane is capable of operating aboard ship in
inclement weather. It is designed to be stowed on the
flight deck of an aircraft amphibious assault ship,
where it will be exposed to extreme open-sea weather
conditions and the corrosive effects of a saltwater
atmosphere.
In
service,
the
crane
will
lift
crashed/damaged aircraft from various locations and
attitudes and move loads on a rolling and pitching ship
to a safe parking zone on the flight deck.

SHIPBOARD
FIRE-FIGHTING
VEHICLE.—The P-25 shipboard fire-fighting vehicle
(figs. 9-9 and 9-10) is a four-wheel (two-wheel drive),
six-cylinder,
turbocharged,
liquid-cooled,
24-volt,
diesel-powered vehicle with a hydrostatic drive system
that transmits power to the rear wheels. Steering is
preformed by a single hydraulic cylinder and tie-rod
assembly that controls the front wheels. Dynamic
vehicle braking is provided by the hydrostatic drive
system. When the accelerator is released, the brakes
automatically engage.
Separate tanks within the
vehicle chassis carry 750 gallons of water and 55
gallons of AFFF (Aqueous Film-Forming Foam).
Three 20-pound fire extinguishers containing Halon
1211 (halogenated extinguishing agent) are stored on
the right side of the vehicle. One nursing line
connection on each side of the vehicle provides AFFF
mixture from the ship's system directly to the vehicle's
water pump.
The vehicle has seating for a crew of two. The
driver compartment is located at the left forward end of
the vehicle and contains the main control panel for
activating the fire-fighting systems. AFFF can be
sprayed from both the forward turret nozzle and
handline hose reel nozzle.
These nozzles operate
independently and can be used simultaneously to make
this vehicle ready for fire-fighting duty.
