Advantages
Forged 40Cr steel with quenching & tempering treatment, combining high strength and toughness, good impact resistance for alternating heavy‑load lifting conditions.
Precisely machined gear teeth ensure smooth transmission, low meshing noise and high transmission efficiency.
High‑accuracy tooth surface provides good wear resistance, extending service life and reducing equipment failure risks.
Specially designed for lifting equipment, compatible with fixed crane transmission systems with good interchangeability.
Matters Need to Attention
Inspect gear tooth surface before assembly. No dents, cracks or burrs are allowed, and mating surfaces shall be kept clean.
Control meshing clearance and alignment accuracy to prevent partial tooth wear or tooth breakage caused by offset load.
Ensure sufficient lubrication during operation, regularly check lubricant condition to avoid dry friction accelerating tooth damage.
Over‑load operation and impact overload are prohibited. Regularly inspect tooth wear and cracks for timely maintenance or replacement.
