Brief Introduction and Structure

Crane drum is the component to wind wire rope in the lifting mechanism.

Crane drum consists of drum shaft, flange type annular gear,drum hub,bearings,bearing pedestal.

When one end of drum is equipped with the switch of rotary type position limitation limiter,it must ensure to make drum shaft and rising limit switch rotate synchronously.

Classification of Crane Drum

1.Cast iron type grooved crane rope drum
1. The material of this kind of crane drum is cast iron HT200.

2. Cast iron type crane drum is more

prevalent than the other two as follows.

3. Centrifugal casting is used in the process of production.

4. The wire rope can be better protected owing to the material of cast iron.

2.Stell plate type grooved crane rope drum
1. The material of this kind of crane drum is steel plate, Q235, Q345.

2. It is more common than cast steel type crane drum.

3. Welding is used in the production process of steel palte type crane drum .

4. It is easy and convenient to produce.
