DC Drive Drawworks of Drilling Rigs High Load Capacity
Bearings all adopt roller ones and shafts are made of premium alloy steel.
Driving chains with high accuracy and high strength are forced lubricated.
The main brake adopts hydraulic disc brake, and the brake disc is water or air cooled.
The auxiliary brake adopts electromagnetic eddy current brake(water or air cooled) or pneumatic push disc brake.
