Φ41.4 Rope Lebus Drum Sleeve Right Hand 60° M16 Countersunk Screw Fastening

Product Description

This Q355D drum sleeve adopts Lebus rope groove with 60° right-hand helix, suitable for wire rope of Φ41.4±1. It features precise machining with controlled hole tolerance, and can be firmly assembled with plain drum by 52-M16 countersunk socket head cap screws. Finished surface with burr-free treatment reduces wire rope abrasion and ensures stable lifting operation. Custom processing is available for matching heavy-duty winch drums.

Technical Parameter

Advantages

• Material advantage: Q355D has excellent low-temperature impact resistance, suitable for heavy-duty operation outdoors and in cold environments.
• Rope groove design: Lebus 60° right-hand helix rope groove keeps wire rope neatly arranged, preventing rope overlapping and biting, extending rope service life.
• Machining precision: Strict tolerance control for hole verticality and position, good fitting performance, easy installation and stable connection.
• Surface treatment: Burr-free finish without scratches, reduces friction damage to wire rope for reliable long-term operation.

Matters Need to Attention

1. Inspect the drum shell surface and rope grooves before installation, ensure no dents or burrs and clean holes to prevent wire rope damage.
2. Use matched 52-M16 countersunk socket head cap screws for assembly, tighten evenly with specified torque to avoid loosening.
3. Confirm the wire rope size is Φ41.4±1 before operation. Overload, sudden start and stop are forbidden to protect the rope groove.
4. Regularly check screw tightness and groove wear, clean dirt inside grooves. Extra inspection is required under low-temperature conditions.
5. Keep proper protection during storage. Avoid long-term outdoor stacking to prevent rust. Protect the rope groove surface during lifting.
