Advantage
Made of 40Cr alloy steel with quenched and tempered treatment, it delivers high strength, wear resistance and fatigue resistance, resisting deformation under heavy load and extending service life.
Precisely machined right-hand rope grooves with 65.24mm pitch and 38 stable grooves, guiding oderly wire rope arrangement to prevent rope squeezing and tangling and reduce wire rope wear.
High-precision machining of φ605H11 inner bore with strict tolerance, achieving excellent fit with the drum shaft for easy installation and good coaxiality during operation.
Integrally formed grooves structure with strong overall rigidity, suitable for large hoisting winches. Custom sizes and groove parameters can be provided according to drawings.
Matters Need to Attention
Inspect the inner bore and rope grooves surface of the drum sleeve before assembly, remove burrs and iron scraps, and confirm no processing defects prior to installation.
Ensure good coaxiality during assembly. Forcible pressing is forbidden to prevent inner bore deformation and loss of rotating precision.
Verify the wire rope specification matches before operation. Overloading is prohibited during working to avoid groove damage caused by impact load.
Regularly check rope groove wear, clean debris inside grooves and apply proper lubrication to extend service life of drum shell and wire rope.
Store in dry and ventilated place with proper protection, avoid collision and scratches on the precision-machined groove surface.
