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