Engineered for 41 mm wire rope systems that demand exceptional storage capacity, this Lebus groove drum sleeve (model LBSS-DN41-D1440-L2365) delivers 3400 meters of total rope length across 11 winding layers. The sleeve features 56.5 precision-machined groove turns with a right-handed 50° lead angle, ensuring controlled multi-layer spooling that eliminates overlapping and rope crushing. Key geometric parameters include a 1440 mm groove bottom diameter and a 1481 mm first-layer rope center distance, both calculated to maintain a consistent fleet angle throughout the entire winding cycle. Secure attachment is provided by six M20 countersunk socket head screws, enabling both robust mounting and simple field replacement when needed.

What sets this drum sleeve apart is its remarkable rope storage capacity—3400 meters of 41 mm wire rope arranged over 56.5 groove turns and 11 winding layers. Such capacity is specifically suited for deep-water offshore operations and extended-reach lifting scenarios. The groove geometry incorporates a 55° transition segment that smoothly guides the rope through crossover zones, flanked by 35° parallel sections that maintain stable rope seating during continuous winding. The 41.85 mm pitch is precisely matched to the 41 mm rope diameter, providing optimal clearance that minimizes frictional heat and wear. Bolt-on installation using six M20 countersunk screws, combined with a 4-6 mm cutting gap, simplifies assembly and disassembly during scheduled maintenance.
This high-capacity drum sleeve is specifically designed for offshore mooring winches, deep-sea exploration systems, and large-scale port cranes where extended rope length is a mission-critical requirement. The 3400-meter capacity makes it an ideal choice for floating production storage and offloading (FPSO) vessels, whose winch systems must accommodate substantial cable lengths for precise station-keeping. In mining hoists and heavy-lift construction cranes that rely on 11-layer winding, the Lebus groove profile guarantees consistent spooling performance across the full depth of wrap. For operators who need a durable, serviceable drum liner that combines exceptional storage volume with precision rope guidance, this sleeve provides proven reliability in both marine and industrial environments.
