Abstract

The invention relates to an underframe for a rail-borne vehicle for transporting freely movable loads, more specifically the underframe of a railroad crane. The underframe has a plurality of curve-negotiating wheel sets which are accommodated in bogies and mounted in a running-gear frame for rolling on running rails. A supporting-wheel set including two supporting wheels is provided to selectively relieve the load on the curve-negotiating wheel sets. The supporting-wheel set is fastened to the vehicle so that the supporting wheels may be raised to a rest position above the running rails and lowered from the rest position to an operative position in which the supporting wheel rests with adjustable pressure on the running rails.
