60° Fold Angle Lebus Groove Drum Deburr & Edge Rounding Symmetric Screw Thread

Product Description

This drum is made of DH36 and Q355B steel, equipped with 60° folded Lebus rope groove with fully symmetrical left and right-hand threads. Manufactured in accordance with welding specifications, it features slag-removed and polished welds plus deburred sharp edges for high structural strength. It is widely used for lifting and marine winch equipment, available for custom production to ensure smooth and ordered wire rope winding.

Technical Parameter

Advantages

• Dual material options DH36 & Q355B. DH36 delivers great impact resistance for marine projects; Q355B balances strength and cost for general lifting applications.
• 60° folded Lebus rope groove with fully symmetrical left & right-hand threads. It keeps wire rope neatly layered, reduces extrusion and abrasion, and extends wire rope service life.
• Fabricated per GB welding standards. Bevel preparation for thick plates, slag removal & weld polishing, deburred sharp edges to minimize stress concentration and boost safety & durability.
• Custom dimensions and anti-corrosion coating available. Suitable for various lifting and marine winches to match your project requirements.

Application

This Lebus grooved drum fits multiple heavy-duty winch systems. The DH36 version is designed for marine engineering such as offshore platforms and ship cranes, capable of withstanding humid and high-impact offshore conditions. The Q355B version is widely adopted for onshore lifting applications including port cranes, construction machinery and mine hoisting equipment. The symmetrical 60° folded rope groove ensures stable multi-layer wire rope winding for heavy-load and long-stroke hoisting and pulling tasks. Custom fabrication is available to match different winch host requirements.
