The role of the drum group:

The drum group is an important part of lifting machinery.

The structure of the drum group:

The drum set consists mainly of drum, drum shaft, gear plate (or big gear), drum hub, bearing body and bearing.

Drum processing materials:

The drum processing materials are usually not lower than ht20-40 cast iron, which can be made by ZG25, ZG35 cast steel, or Q235B, Q345B plate welding.

If the lifting height is bigger, in order to reduce the size of the drum, can be used with pilot spiral groove or smooth surface of multi-layer winding drum, but the wire rope wear faster, apply to slow and the type of work is lighter, lower tonnage crane. The steel sheets are mainly used for heavy lifting machinery with high tonnage and high performance.
