Drawworks

Product Details:

 Mechanical drawworks features
 
  • 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 high speed end and low speed end of drum adopt pneumatic tube clutch; the brake drum and brake disk adopt forced water cooling; the brake drum and brake disk are case-hardening treated with excellent wear-resistance capacity and long service life.
  • The tooth profile of sprocket is intermediate frequency hardening treated, all shifting clutch are involute spline type clutch
  • The main brake is band brake or hydraulic disk brake, the auxiliary brake is eddy current brake (water-cooled or air-cooled).
