Wheelsets as a key component of the crane traveling mechanism, that its quality is good or bad will have a significant impact on its usage, GB / T6392-2008 has special regulation for its chemical composition of materials, mechanical properties, heat treatment mode, hardness, surface quality and precision. Crane wheels are relatively easily damaged components. Based on the crane use characteristics, it requires wheel tread with high hardness, and have some quench-hardened case depth and transition layer (depth>10mm, hardness HRC40-48), so that improve its performance of carrying capacity, wear resistance& contact fatigue resistance. At the same time, it requires its matrix organization to have good mechanical properties &good organizational status, the hardness shall reach HBS187 ~ 229, so that it has high toughness, improving impact resistance and cracking resistance performance.
Forged & Casting Crane Wheels are available in a wide range of standard sizes. In addition, crane wheels to meet your special design requirements can be produced in virtually any size, configuration and surface finish condition. We maintain a large inventory of carbon and alloy steels to meet your specific needs.
- Material: The casting wheel material generally is 50SiMn, ZD45, ZG55. The forging wheel material generally is DG65Mn and 42CrMo.
- Treatment: The heat treatment is quenching or hardening and tempering.
- Size: Special designs are available, Making according to clients demand. Precise measurement and surface finishes are available.
- Inspection: In-house and the third party. Inspection: all items are checked and tested thoroughly during every working procedure and after the product is finally manufactured to ensure that best quality product goes out on the market.
