As an undercarriage part that not only bears the load but also rotates continuously to generate friction with the track shoes, the sprocket is a relatively easy-to-damage part, and hardness is the key to testing the quality of the crawler crane sprocket. In the production process, we have undergone mature overall heat treatment according to the original quality standard, so that the hardness of the driving wheel body is HRC 48-56, and there is a certain depth of quenching layer and transition layer to improve the bearing capacity, and keep high resistance to contact fatigue. After a series of machining and inspection processes, we make sure the sprockets which are delivered to your crawler cranes finally are the best quality.

We produce sprocket 100% in accordance with standard drawings and dimensions. Through digital finishing technology, the dimensional error is minimized, which not only ensures the matching with the installation of the traveling device, but also makes it perfectly meshed with the crane track shoes to reduce the friction of the parts, extending its service life by 30% and maintaining unmatched reliability under the harshest working conditions. Many customers have feedback that our sprockets have better performance in practical applications. Below are the available crawler crane sprockets: Hitachi sprockets, Sumitomo sprockets, Kobelco sprockets, IHI sprockets, Nippon Sharyo sprockets, Terex sprockets, American sprockets, Manitowoc sprockets, Demag sprockets, Link Belt sprockets, Liebherr sprockets, Sany, XCMG, Fuwa, Zoomlion sprockets.
