Epoxy Primer Drum RAL7031 Topcoat Lebus Groove For Winch
Product Description
This drum is manufactured from Q355D material with 60° right-hand Lebus double-parallel rope grooves. Sharp edges are broken, burrs and flashes are fully removed after machining. The welding is firm without missed-welding defects, and stress-relief treatment is performed after welding. After sandblasting, the drum is coated with epoxy zinc-rich primer and polyurethane topcoat for superior anti-corrosion performance. It delivers stable mechanical properties and fits for various hoisting winch working conditions.

Advantages
Q355D base material features good low-temperature toughness and high impact resistance, suitable for heavy-duty complex working conditions.
60° right-hand Lebus double-parallel rope grooves guide neat wire-rope winding, reduce extrusion and wear, and extend wire rope service life.
Post-weld stress-relief treatment minmizes welding deformation and improves operating stability of the drum.
Complete coating system of sandblasting, epoxy zinc-rich primer and polyurethane topcoat provides outstanding anti-corrosion performance for harsh outdoor environments.
Sharp edge breaking and burr-flash removal prevent wire rope scratching for safer assembly and operation.
Matters Need to Attention
Before installation, inspect the rope groove surface for impact damage. Ensure all burrs and sharp edges are fully removed to avoid wire-rope cutting.
Use properly-spcified wire rope, arrange rope following the 60° right‑hand groove direction to prevent rope disorder and extrusion.
Overload operation is strictly forbidden to avoid structural deformation and failure.
Regularly check welds and paint coating. Repair cracks on welds and peeling paint timely for anti‑corrosion maintenance.
Inspect drum operation periodically. Stop equipment immediately if abnormal vibration or noise occurs for troubleshooting.
