TM 5-3810-306-10 LOCATION AND DESCRIPTION OF MAJOR COMPONENTS Cab Assembly The cab is all-steel, acoustically-treated, and fully- enclosed with tinted safety glass window. It contains all engine and crane controls and indicators for complete operation of the crane including outrigger controls. The cab also contains an operator’s seat, heater, defroster, electric windshield wiper, dome light and fire extinguisher. Engine A diesel engine is housed in a compartment at the rear of the frame. The engine provides crane mobility, drives the hydraulic pumps, charges the air system via the compressor, and drives the alternator. Fuel Tank A 100-gallon (378-liter) capacity fuel tank is mounted on the left side of the frame between the axles. The filler cap, located on the side of the tank, is accessible from ground level. Torque Converter The torque converter is mounted on and driven by the engine. It drives the three-section hydraulic pump, the two-section hydraulic pump, and the converter/transmission charging pump. Transmission The transmission is a powershift six-speed (forward and reverse) type. The transmission is mounted on the carrier frame near the center of the crane. Axles The front and rear axles are drive and steer (axles) with brakes at all four wheels. Hydraulic Reservoir The hydraulic reservoir is located on the right side of the carrier. The reservoir contains hydraulic system oil and includes a filter and by-pass valve. Turntable Assembly and Swing Mechanism An anti-friction roller bearing supports the superstructure on the carrier frame allowing 360 degrees continuous rotation (swing) in either direction. The bearing is driven by a hydraulic motor and gear reducer/brake arrangement mounted above the bearing in the turntable. Boom Assembly The two-section boom extends from 34.4 to 60.4 feet (10.52 to 18.46 meters). The boom is mounted on a turntable and is raised/lowered and extended/retracted by hydraulic cylinders. Auxiliary Boom Nose The auxiliary boom nose consists of a welded extension with a sheave assembly. The auxiliary boom nose is mounted on the boom nose. Main Hoist The main hoist provides power for all load raising and lowering operations. The main hoist is mounted at the rear of the boom on the turntable. Auxiliary Hoist The auxiliary hoist provides power for all load raising and lowering operations when the auxiliary boom nose is installed and the overall ball is being used. The auxiliary hoist is mounted on the counterweight. 1-4
