General The operating clutches are of the internal expanding type and controlled hydraulically. The band assemblies are composed mainly of a clutch shoe with lining, a clutch actuating arm and actuating arm retracting spring, and a band retracting spring. The brakes are of the external-contracting type mounted on the outside of the clutch drums. They consist chiefly of a two-part hinged-attached brake assembly with lining. One end of the band assembly is anchored and the other is actuated. The boom hoist brake is held in the engaged position by a spring and released hydraulically when the boom hoist clutch is actuated. The main hoist and haul-back brakes are controlled mechanically and are engaged by pressure on the brake pedals. 138. Boom Hoist Clutch Band a. Removal.
