Product Introduction
Crane rope drum is a part of crane lifting mechanism which is used to full in, entwine, and store wire rope. The rope drum is consisted of drum shaft, flange type annular gear, drum hub, bearings, bearing pedestal, etc. Every part of crane rope drum is engineered and manufactured to meet the operational and safety requirements of industrial crane applications.
Technical Description
- Depth of groove should be 1-0.5 times of wire rope diameter. Throat/ tread diameter is 24 to 30 times wire rope diameter.
- Standard throat angle is 35°.
- Rope seat radius equals to rope diameter and clearance, which should be support 135-150°of rope circumference and the surface should be slippery.
- Wear can be measured with “Groove Gage”.
Product Advantages
- Rope drum is usually made of cast iron.
- However, on special occasions or based on your special requirements, crane rope drum can directly weld with cast steel or steel plate.
- Customized rope drum is available from KOSTA CRANES.
