Designed for demanding 45 mm wire rope applications, this heavy-duty drum liner is manufactured from Q355B high-strength low-alloy steel. The split-type sleeve features a right-handed Lebus groove with a tangential crossover profile that effectively prevents rope overlapping during multi-layer spooling. Engineered to deliver superior yield strength and impact toughness, this bolt-on component reliably supports continuous heavy-load lifting operations. The two-piece split design simplifies field replacement—technicians can install a new liner without disassembling the entire drum assembly, substantially reducing equipment downtime and maintenance costs.

This drum liner leverages the inherent strength of Q355B low-alloy steel, offering an optimal balance between hardness and ductility for shock-loaded hoisting systems. The right-handed 60° groove orientation precisely matches winch rotation direction, ensuring the rope naturally tracks into each layer without sideward deviation. Lebus tangential crossover points are strategically engineered to guide the wire rope smoothly from one tier to the next, eliminating the crushing and jamming issues common with standard helical grooves. Precision machining ensures groove dimensions perfectly match 45 mm rope characteristics. The bolt-on split configuration empowers maintenance teams to restore original spooling accuracy by exchanging only the worn liner, leaving the parent drum intact for the life of the equipment.
This heavy-duty drum liner is specifically engineered for large-capacity offshore pedestal cranes, shipboard deck machinery, and port container spreaders where 45 mm wire rope endures extreme tensile stresses. The right-handed orientation is particularly well-suited for winch systems with clockwise rotation requirements commonly found in European and Asian marine equipment. In floating production storage and offloading vessels and underground mining hoists, the Q355B steel construction resists continuous cyclic fatigue without permanent deformation. The replaceable design philosophy delivers maximum value in high-wear environments, allowing operators to schedule maintenance during planned operational windows rather than suffering unplanned extended shutdowns. For OEMs and marine fleet managers seeking a durable, serviceable large-diameter rope management solution, this precision-machined sleeve provides proven reliability in the field.
