DrawWorks:

Siquan Machinery has rich experience on providing Mechanical drawworks, DC Drawworksand AC VF drawworks.

Mechanical drawworks:

All bearings are roller bearing, all shaft material are alloy steel; The chains are high precision and high strength chains with forced lubrication;The drum is grooved. the brake drum and brake disk adopt forced water cooling;The high speed end and low speed end of drum adopt pneumatic tube clutch, the brake drum and brake disk are case-hardening treated with excellent wear-resistance capacity and long service life.

The main brake is band brake or hydraulic disk brake, the auxiliary brake is eddy current brake,The tooth profile of sprocket is intermediate frequency hardening treated, all shifting clutch are involute spline type clutch.
