This heavy-duty Lebus grooved winch drum is fabricated from Q355B high-strength alloy steel, designed as a complete drum assembly for 46 mm wire rope applications. The drum features a precision-machined Lebus groove pattern with an 80° lead angle, available in both left-handed and right-handed orientations to accommodate diverse winch configurations. A full epoxy primer coating is applied to all exterior and interior surfaces, providing robust corrosion resistance for offshore and marine environments.

The Lebus groove profile employs a three-stage transition design—80° entry section, 100° crossover zone, and 80° exit section—engineered to guide the wire rope smoothly between layers without requiring external compression mechanisms. The 48.5 mm pitch dimension is precisely calibrated to the 46 mm rope diameter, maintaining optimal clearance that reduces frictional wear on both components. Surface protection is achieved through a comprehensive epoxy primer application, forming a corrosion-resistant barrier against saltwater, humidity, and chemical exposure. Post-machining deburring eliminates all sharp edges, preventing localized rope abrasion during high-tension winding operations. Integrated flanges are welded as part of the single-piece assembly, eliminating potential failure points associated with bolted flange attachments.
This Lebus grooved winch drum is engineered for main hoist and mooring systems aboard offshore support vessels, anchor handling tugs, and floating production platforms. The dual-orientation groove design—available in both left-hand and right-hand configurations—simplifies integration with existing winch drives across Korean, European, and American marine equipment standards. The epoxy primer coating qualifies the drum for sustained exposure to marine atmospheres, making it suitable for open-deck installations subject to salt spray and weather extremes. Typical applications include supply vessel deck cranes, tugboat towing winches, offshore crane main hoists, and heavy-lift construction equipment operating in coastal environments. For shipyards, offshore contractors, and original equipment manufacturers requiring a durable, corrosion-protected winch drum with precision Lebus grooving, this assembly provides reliable performance across the full range of demanding marine lifting operations.
