This heavy-duty Lebus groove drum liner is specifically designed for 36.9 mm wire rope applications, incorporating a left-handed 50° lead angle and a robust 37.9 mm pitch. Model DN36.9-D1450-L2672 features a 70.5-turn groove pattern with an overall length tolerance of ±1 mm. The split-type sleeve mounts securely using 54 M20 countersunk socket head screws, creating a serviceable connection to the parent drum body. With a groove bottom diameter of Φ1450 mm and a first-layer rope center diameter of Φ1486.9 mm, this drum sleeve ensures dependable multi-layer spooling performance for demanding heavy-lift operations.

A key differentiator of this drum liner is its heavy-duty bolt-on attachment system, featuring 54 M20 countersunk socket head screws that allow straightforward field replacement without complex teardown. The left-handed 50° lead angle is precisely matched to fleet angle requirements, enabling controlled layer-to-layer transitions across all 70.5 rope turns. The generous 37.9 mm pitch provides optimized clearance for the 36.9 mm wire rope, reducing friction and heat buildup during high-speed spooling. Additionally, machined 10 mm × 45° chamfers at critical edges minimize stress concentrations and protect the rope from abrasive contact during entry and exit.
This heavy-gauge drum sleeve is purpose-engineered for large-scale lifting equipment operating with 36.9 mm wire rope in harsh environments. Common deployments include offshore pedestal cranes, port container handling systems, and mining hoists where reliable multi-layer winding directly impacts operational safety. The bolt-on split design proves especially valuable in heavy marine applications with constrained maintenance access, allowing crews to replace worn grooving without removing the entire drum assembly from the vessel or structure. Other applications extend to floating production storage vessels, shipboard cranes, and high-capacity winches requiring precision grooving with minimal downtime. For operators seeking a durable, serviceable drum liner built for rigorous industrial and marine conditions, this component delivers proven field performance.
