Product Description

This Lebus split drum shell is manufactured from Q355D steel, with 60° right-hand rope grooves and bolted connection, net weight 1311.4kg. It suits Φ52mm steel wire rope with 30.5 rope grooves, guiding the wire rope to wind smoothly and prevent disorder and abrasion. The surface is coated with epoxy zinc-rich primer to deliver excellent rust and corrosion resistance. Custom fabrication is available according to drawings, widely used for heavy-duty crane winches with convenient installation and maintenance.

Technical Parameter

Advantages

1. Built with Lebus 60° right-hand helical rope grooves, specially designed for Φ52mm large-diameter wire rope. It arranges wire rope neatly to avoid rope crushing and overlapping, greatly extending wire rope service life and cutting your spare part expenses.
2. This split drum shell is made of high-strength Q355D steel with bolt-on assembly. You only need to replace the worn shell instead of the whole drum, effectively reducing machine downtime during maintenance.
3. Coated with epoxy zinc-rich primer for outstanding anti-rust and anti-corrosion performance, it works reliably under heavy-duty harsh outdoor environments including ports, mines and large construction projects.
4. Precision machined with 30.5 rope grooves for even load distribution under heavy loads. Custom production per drawings is available, ideal for new heavy winch assembly and equipment retrofitting.

Matters Need to Attention

1. Inspect the drum shell, bolts and rope grooves thoroughly before installation, remove burrs and debris, verify dimension matching with winch drum, and avoid forced assembly.
2. Tighten bolts diagonally and evenly to specified torque. Recheck bolt preload regularly to prevent loosening under heavy load operation.
3. Use Φ52mm steel wire rope only. Overload operation is prohibited. Inspect wire rope routinely to prevent rope damage that accelerates drum groove wear.
4. Keep away from strong corrosive agents during storage and operation. Touch up coating damage promptly to maintain the anti-corrosion performance of epoxy zinc-rich primer.
5. Periodically check rope groove wear. Replace the drum shell once reaching wear limit to prevent unexpected equipment breakdown.
