Forged mobile crane rail steel wheel

Crane Wheels are the most important parts in traveling unit and also are the most vulnerable parts due to the strong impact and wear between wheel and rail. Flange wear, flange breakage and fatigue pitting are the frequently encountered problems. When the crane wheels are broken, the repair and replacement are complex and very time-consuming. To ensure the high quality of the crane wheels assembly, every step in design, material, heat treatment and processing technology is properly and precisely executed in VOHOBOO.

overview

According to the different forming process, there are two typical types: casting wheels and forging wheels. Due to different material, heat treatment, we just can’t make a brief contrast between them. Because of different design of crane, the overhead crane wheels are often very different. So the custom designed wheel and OEM is accepted, in fact, is the most common case in export. Meanwhile, our engineers are always ready to make recommendations when these wheel need to be integrated into complete wheel assemblies or in a very specific application.

Main Features

1.Material: The casting wheel material generally is 50SiMn, ZD45,ZG55. The forging wheel material generally is DG65Mn and  42CrMo. 2.Treatment: The heat treatment is quenching or hardening and tempering. 3.Size: Special designs are available, Making according to clients demand.Precise measurement and surface finishes are available. 4.Inspection: Inhouse 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 in the market.

Feature and advantage

Manufactured from fine gain, fully killed, vacuum degassed forged medium carbon steel Heat treated using our in house processes to provide a uniform contour hardness in the tread and inner flange wear surfaces, while maintaining a ductile core to resist shock loads Resistant to flange fracture or wear Designed to resist pitting and spalling Reduce maintenance cost of your wheels and wheel assemblies Improve the life of your rail Provide an additional 40% load carrying capability over rim toughened wheels Delivery in 3 weeks, less when required

Application places

1,extensively used in factories, workshops, warehouses and many other occasions to hoist materials directly, 2,installed on the straight or curve I-steel beam of Single-girder Cranes to lift goods. 3,It can also be used together with Electric Hoist Double-beam, gantry crane and slewing cranes to hoist different items and so on. It has so many appllication usages just for its advantages, such as: tight structure, convenient operation, light weight, wide common use and so on.
