Design Features of drawworks:
l All bearings are roller bearings. Shafts of drawworks are made of alloy steel.
2 Drum of drawworks is grooved. Ventilating air clutches constitute the high and low speed ends.
3 Main brake of drawworks is hydraulic disc brake. The disc of brake is cooled by water or air.
4 Auxiliary brake is Electromagnetic eddy current brake, cooled by water or air.
5 Being shifted though air clutch.
6 Being transmitted through chains.
7 Chains are lubricated forcedly by thin oil, bearings are lubricated by grease.
8 Split construction
