Custom Drawing Wire Rope Drum according to Client Specs
Product Overview
In the hoisting mechanism of a crane, the drum group plays an essential role in winding the wire rope and enabling the lifting and lowering of heavy loads. As the critical link between the power source and the load, the drum group directly influences hoisting stability, operational safety, and the service life of the entire equipment. A complete drum group typically consists of the drum body, drum shaft, gear coupling (or main gear), drum hub, bearing housings, and bearings.
Material Options & Process Advantages
We offer three material solutions for drum manufacturing, each selected based on application requirements:
| Material | Grade | Features & Applications |
|---|---|---|
| Gray Cast Iron | HT20-40 (min. HT200) | Cost-effective; requires aging treatment to relieve internal stresses. Suitable for standard-duty applications. |
| Cast Steel | ZG25, ZG35 (equivalent to ZG270-500) | High strength and toughness; requires annealing. Ideal for heavier load conditions. |
| Welded Steel Plate | Q235B, Q345B | Excellent structural strength; designed for high-capacity cranes and demanding performance requirements. |
Compared to traditional cast drums, welded steel plate construction is increasingly preferred in global markets, especially for large-diameter drums where cast options present manufacturing challenges.
