HOIST MACHINERY The hoist machinery consists of a motor coupled to two gear reductions which drive the hoist drum. A spring set, air released plate disc type brake is mounted to the motor. A hoist rotary encoder limits hoist travel. The hoist motor is connected to the motor pinion shaft by a gear tooth coupling. 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.
