HOIST MACHINERY The hoist machinery consists of a motor coupled to two gear reductions that drive the hoist drum. A spring-set, air-released disc brake is mounted to the motor. A hoist encoder limits hoist travel. A multiple coupling shaft assembly connects the hoist motor to the motor pinion shaft. The first reduction gear set is mounted in an oil lubricated, totally enclosed gearcase. The second reduction gears are drip lubricated with open gear lubricant from the automatic lubrication system. All shafts run on anti-friction bearings. The hoist bull gear is bolted to a spider on the left-hand side of the drum. The hoist drum is manufactured with machined, flame hardened rope grooves. Drum spider stub shafts turn on anti-friction bearings supported by side frames which are bolted to the rotating deck.
