ABSTRACT:
A crawler vehicle, e.g. a drill rig, has a main frame that is carried by two crawler assemblies having frames that are journal-mounted to the main frame. A transverse pivotable beam is coupled between the crawler frames by means of journal bearings that are obliquely inwardly directed so that the axes of the four bearings intersect each other at a single point. The transverse beam supports the main frame by means of a journal bearing, the axes of which lie in a vertical longitudinal plane through said point of intersection. All the journal bearings have an elastic bushing between the journal and the bearing box and relative movements in the bearings are taken up as shearing deformations in the elastic bushings.
