Double Fold Lebus Groove Winch Drum Q355D Left-Hand 60°
1.Double Fold Lebus Groove Winch Drum Q355D Left-Hand 60° Description
Q355D LEBUS grooved winch drum adopts double-fold Lebus rope groove design, available in left-hand/right-hand 60° spiral options. It is specially developed for multi-layer steel wire rope winding, which effectively prevents rope disorder, reduces wire rope wear and prolongs the service life of both the drum and steel cable.
Fabricated from high-strength Q355D steel plate and pipe, the drum supports fully customized size, single/double drum structure and shaft configuration. It matches wire ropes of 3–50 mm with rated pulling force ranging from 3 KN to 400 KN, compatible with electric and hydraulic winches. Widely applied in towing, construction, mining, port terminal and oilfield drawworks.
Strict machining and welding standards are implemented: post-weld stress relief, precise tolerance control, sandblasting plus 100μm+ epoxy zinc-rich & polyurethane anti-corrosion coating, ensuring stable performance under heavy-load working conditions.

3.Double Fold Lebus Groove Winch Drum Q355D Left-Hand 60° Advantages
Over the past decades, winch equipment has been widely applied with diversified transmission and structural forms, yet the wire rope winding logic of winch drums remains unchanged. Our independently developed LEBUS double-fold rope groove drum delivers prominent performance merits:
(1)Double-line fold groove design, specially optimized for multi-layer steel wire rope winding;
(2)Effectively eliminate or mitigate wire rope disorder, extrusion and abrasion;
(3)Key structural parameters including drum opening range, base diameter, guide block position, rope socket structure, groove pitch and spiral angle of parallel/climbing sections are precisely calibrated to guarantee stable winding;
(4)Significantly extend service life of both steel wire rope and drum, reduce field maintenance failures for oilfield, mining and port hoisting equipment.
4.Double Fold Lebus Groove Winch Drum Q355D Left-Hand 60° Applications
This Q355D LEBUS grooved winch drum fits heavy-duty winding and traction scenarios that require long-term stable load-bearing performance. As a key structural part of hydraulic & electric winches, it works perfectly with port haulage gear, construction tower lifting assemblies and oilfield drawworks, with outstanding anti-corrosion coating and solid welded construction to stand harsh working environments. Within mining machinery, it pairs well with heavy-load mine winches that need steady multi-layer wire rope coiling all the time. Its exclusive double-fold 60° LEBUS rope groove structure greatly lowers rope abrasion and messy winding, simplifying daily wire rope inspection and later part replacement. For equipment manufacturers and after-sales service teams looking for customizable high-tensile drums compliant with national machining standards, this product delivers a durable, fully tailored solution for high-intensity continuous operation.
