Mechanical driven drawworks

Design Features

1.Bearing are rolling ones and shafts are made of alloy steel.

2.Chains with high accuracy and high strength are pressure lubricated.

3.On the drum there is a spiral groove.The low-speed & high-speed  ends of drum shaft are equipped with a ventilating air clutch.The brake rim(or disc) is water cooled and the surface is intermediate frequency quenched,which increases long service life.

4.The contours of the sprocket teeth are intermediate frequency quenched.All clutches of shifting gears are of involute spline type.

5.A band or disc brake is regarded as main brake and an eddy current brake(water or air cooled)as auxillary brake.
