Kingrail Parts manufactures European and non-standard crane trolley wheels according to customer requirements. Wheel materials include 42CrMo4, AISI4140, 41Cr4, A504, SSW-Q1R and other high-quality forged steel or cast steel. The gear materials are 45#, 40Cr, and 42CrMo.
Our gears adopt a quenching and tempering heat treatment process to ensure the strength and toughness of the gears, as well as the comprehensive mechanical properties of the gears. Some gears adopt a surface quenching and tempering heat treatment process, and the surface hardness of the gear can reach HRC40-55. Therefore, the hardness of the gear can be improved, the wear resistance of the gear can be increased, and the service life can be extended.
Gear crane wheels are widely used in various lifting and transportation equipment, especially large-tonnage equipment, such as LD single-girder cranes, loading and unloading bridges, dam crest gantry cranes, container cranes, port machinery, etc.
Manufacturing process
Rough machining → Drilling (Welding) → Debur (Chamfer) → Heat treatment(Quenching/tempering/annealing) → Redo heat treatment → Precision machining → Redo finish machining → Finished (finishing/coating) → Package → Delivery
