Mechanical Drawworks

Features of Mechanical Drawworks 1. All bearings are roller bearings. Shafts are made of alloy steel. 2. Chain drive transmits with high accuracy and high strength and has forced lubrication. 3. The drum is grooved. Ventilating air clutches constitute the high and low speed ends. 4. The brake drum (brake disc) is cooled with circulating water. 5. Main brake is band brake or disk brake, the auxiliary brake is eddy current brake (water-cooled or air-cooled. ) 6. The surface is hardened with middle frequency induction, and is very durable for long life. 7. The sprocket tooth profile is hardened with middle frequency induction. Involute serration tooth clutch works as a shifting clutch. 8. Specifications of Mechanical Drawworks
