Abstract

The invention is directed to a running wheel for traveling units which are movable on rails, especially for traveling cranes. The running wheel includes an outer running ring, a resilient damping hub inserted in central opening of the running ring. The hub transmits torque received from a drive shaft to the running ring. The resilient damping hub effectively intercepts occurring torque peaks forward of the gear unit and drive shaft, by elastically deforming while maintaining a connection at the central opening of the running ring without play.
