Features of Mechanical Drawworks

All bearings are roller bearings. Shafts are made of alloy steel.

Chains with forced lubrication can transmit with high accuracy and high strength.

The drum is grooved Ventilating air clutches constitute the

high and low speed ends;

The brake drum(brake disc) is dealt with forced cooling with

circulating water;

The surface case was hardened with medium frequency,

and is durable;

The tooth profile of sprocket was hardened with medium

frequency. Involute serration tooth clutch worked as shifting

clutch.

Main brake is band brake or disk brake, the auxiliary brake is eddy current brake (water-cooled or air-cooled). Specifications of mechanical drawworks Model		JC-40	JC-50	JC-70
