Description
Crane Drum
Product Overview and Highlights：
The crane drum, also known as a wire rope drum or rope reel, is a critical component of crane hoisting systems. It is responsible for winding, storing, and guiding the wire rope during lifting operations, ensuring smooth motion, load stability, and operational safety. Crane drums are widely used in electric winches, hoists, and trolley mechanisms of overhead cranes, gantry cranes, and winch systems, where durability and precision directly affect service life and safety.
1.Precision-machined rope grooves for smooth and stable winding.
2.High-strength materials suitable for light to heavy-duty lifting.
3.Optimized flange design prevents rope jumping and misalignment.
4.Heat-treated grooves extend drum and wire rope service life.
5.Fully customizable dimensions, materials, and structures.

FAQs：
Q: What materials are available for crane drums?
A: Common materials include cast iron, cast steel, and welded carbon steel plates, selected based on load and working conditions.
Q: Can the crane drum be customized?
A: Yes. Drum diameter, length, groove type, shaft structure, and material can all be customized.
Q: Why is rope groove hardening important?
A: Hardened grooves reduce wear on both the drum and wire rope, extending service life and improving safety.
Q: Where are crane drums typically used?
A: They are used in cranes, winches, hoists, port equipment, shipyards, mining systems, and heavy-duty lifting machinery.
