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. A/S32P-25 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. 9-5 ANF0908 Figure 9-8.—A/S32A-36A (AACC) amphibious assault ship crane.
