Product Description
Heavy-Duty Wire Rope Drum for Overhead Bridge Crane Hoisting Mechanism
The wire rope drum is the core load-bearing component of overhead bridge crane hoisting system, used to wind, store and guide steel wire rope during lifting operation. Our crane drums are widely matched with single/double girder overhead cranes for workshop, metallurgy, logistics, machinery manufacturing and heavy engineering projects.
Core Advantages
- High Strength Raw Material
Optional Q235B, Q345B, 45# forged steel and cast steel. Reasonable wall thickness design, anti-deformation under heavy load, suitable for continuous heavy-duty working conditions.
- CNC Precision Machined Rope Grooves
Accurate spiral rope groove processing, effectively prevent wire rope jumping, stacking and abrasion, greatly extend wire rope service life. Manufactured comply with GB/T24816 & DIN15021 standard.
- Customizable Structure
Support customized diameter, length, shaft hole, spline, flange size according to customer drawings. Welded type and integral forging type optional.
- Strict Quality Inspection
Raw material inspection → rough machining → finish machining → groove processing → nondestructive testing → painting; Each product can provide test report on request.
- Anti-corrosion Surface Treatment
Shot blasting + anti-rust primer + finish paint; Hot-dip galvanizing available for humid and corrosive environment.
