The crane coupling is a mechanical part used to connect the drive shaft to the driven shaft. During the work of the crane, the deformation is inevitable due to the action of force, especially the deformation of the bridge, which has a great influence on the crane running mechanism. In order to ensure that the crane moving mechanism has good running performance in the case of main beam deformation, and also to compensate for the inevitable errors in the manufacturing and installation process, the crane widely use the coupling with compensation function, such as fixed couplings, mobile couplings, universal couplings, gear couplings, chain couplings, etc.

Crane couplings should be selected according to its working environment, because some crane couplings cannot work in ultra-high temperature or ultra-low temperature environment, some cannot work in dust, sand, steam environment, and some cannot work in oil, acid or alkali environment.

1. SEVENCRANE coupling is safe and reliable with high quality No.45 steel or 42crmo.
2. The heat treatment process is mature and strict.
3. SEVENCEANE can process various types of non-standard model product.
