Right Hand Helical Groove Drum 3 Layers Winding RAL7031 Coating For 10mm Wire Rope

Right Hand Helical Groove Winch Drum 3 Layers Winding RAL7031 Coating For 10mm Wire Rope

Product Description

This drum is fabricated from Q355B steel, designed with right-hand spiral rope grooves for 3-layer winding of φ10mm steel wire rope. Strict welding standards are implemented to avoid welding defects, ensuring stable and reliable structure. Its surface is coated with epoxy zinc-rich primer and polyurethane topcoat in RAL7031 grey, with total film thickness ≥120μm for outstanding corrosion resistance. Custom manufacturing is available to match various hoisting winch systems.

Technical Parameter

Advantage

1. Made of high-strength Q355B steel, it features strong load capacity and excellent impact resistance, resisting deformation under long-term heavy loads.
2. Precisely machined right-hand spiral rope grooves enable neat 3-layer wire rope winding, preventing rope crowding and disorder and extending wire rope service life.
3. Welding process is strictly controlled with no cold solder or missing welds, delivering high structural integrity and reliable operation safety.
4. Dual anti-corrosion coating system: epoxy zinc-rich primer plus polyurethane topcoat in RAL7031 grey, total film thickness ≥120μm, offering great protection against rust and outdoor environmental damage.
5. Custom manufacturing available. Dimensions and groove parameters can be adjusted according to winch working conditions to fit various hoisting equipment.

Application

Made for multi-layer steel wire rope winding, this Q355B winch drum is widely used in a variety of hoisting and winching equipment. It can be matched with construction machinery, port cranes and mine lifting gear for heavy load lifting and retracting operations. It is also suitable for offshore platforms and factory stationary winches, operating stably both indoors and outdoors. Thanks to its reliable anti-corrosion property, it can work under harsh conditions such as humid and dusty environments.
