3.Advantage

• Superior rope‑arranging performance: Double‑folded groove ensures tidy multi‑layer winding, avoids rope jumping and biting, greatly extends wire‑rope service life.
• Modular sleeve structure: Segmented fit‑on design, no drum core replacement required. Easy for installation, inspection and replacement, reduces retrofitting cost.
• Low‑temperature high‑strength material: Q355D features good low‑temperature impact toughness, suitable for offshore and cold field conditions, supplied with EN10204/3.1 material test certificate.
• Uniform stress & wear resistance: Precisely machined grooves distribute rope load evenly, mitigate rope abrasion and wire‑break risk.
• Anti‑corrosion performance: Primer coating improves rust‑proof performance for outdoor and marine working conditions.

4.Application

This drum sleeve is well‑suited for port machinery, offshore vessel winches, and heavy‑duty industrial winches where 41 mm wire rope is adopted in multi‑layer winding systems. The double‑folded Lebus groove pattern makes it particularly effective in applications requiring controlled rope layering without extra compression accessories. Precision‑machined transition sections at both ends allow for smooth rope transition, reducing impact stress during rope winding and direction shifting. Typical deployments include mooring & towing winches, marine lifting equipment, mine hoisting and heavy‑duty material‑handling systems. Its segmented bolt‑on replaceable design enables quick on‑site maintenance, minimizing equipment downtime. For operations demanding consistent spooling performance and reliable anti‑corrosion protection, this Lebus drum sleeve delivers a practical, long‑lasting solution.
