| High Light | Right-hand Lebus grooved drum sleeve ，52mm cable drum sleeve ，LBS sleeve for cable winding | ||
This Lebus grooved Sleeve is fabricated from Q460NE low-alloy high-strength steel, specially designed to match winch drum.It adopts the Lebus segmented rope groove structure.The sleeve is bolted onto the bare drum barrel, eliminating the need for full drum machining.It can be separately manufactured, assembled, disassembled and replaced.
This product is suitable for 52mm diameter cables.The root diameter of the groove is 1500mm, the rope groove pitch is 1500mm,the rope groove pitch is 54.34mm,it features a right-hand 60° groove with a total of 30.5 grooves. The net weight of a single piece is 1311.4KG.Its surface is coated with zinc-rich epoxy primer, delivering excellent anti-corrosion performance for marine environments, making it highly suitable for heavy-duty working conditions of ships and offshore engineering.

(1) Stable multi-layer spooling to protect wire ropes The Lebus segmented groove structure guides orderly multi-layer winding of wire ropes, preventing rope squeezing, interlocking and disordered spooling. It greatly reduces wire rope abrasion, effectively extends rope service life and cuts replacement and downtime costs of offshore equipment.
(2) Split bolted construction for low maintenance cost The grooved sleeve is mounted independently on the drum base. If groove wear occurs, only the sleeve needs replacement instead of the entire drum. It lowers spare part procurement cost and on-site maintenance time, ideal for ship overhaul at sea.
(3) Offshore-grade material with marine corrosion resistance Q460NE base steel offers favorable low-temperature toughness. Combined with zinc-rich epoxy primer, it withstands salt spray and humid marine corrosion, adapting to variable temperature and weather conditions of ocean-going vessels and offshore platforms.
(4) Reliable performance under heavy load with high load capacity Designed for large-diameter Φ52mm heavy wire ropes, it fits high-tension lifting operations of marine winches. Precisely machined groove profile ensures uniform stress distribution, strong resistance to compression and deformation, and stable operation under heavy loads.
(5) Standardized precision machining Rope groove pitch and profile angles are precision machined strictly per drawings. Smooth rope entry transition reduces bending stress on wire ropes. Evenly distributed bolt holes ensure balanced stress during installation.
Suitable for various marine winches, offshore platform lifting winches, mooring winches, salvage winches and offshore lifting equipment. It can be fitted on engineering vessels, offshore support vessels, offshore drilling platforms, for heavy-duty operations such as offshore lifting, anchoring, mooring and marine cargo hoisting.
