Mechanical Drive Drawworks on Drilling Rig
• Drawworks positive gears all adopt roller chain transmission and negative ones adopt gear transmission.
• Driving chains with high accuracy and high strength are forced lubricated.
• The drum body is grooved. The low-speed and high-speed ends of drum are equipped with ventilating air tube clutch.
The main brake adopts belt brake or hydraulic disc brake, while the auxiliary brake adopts configured electromagnetic eddy current brake(water or air cooled).
