ABSTRACT:
A self-propelled track working machine comprises a frame, track working equipment carried by the frame and subjecting the frame to a load and an undercarriage arrangement with two main undercarriages supporting the frame for mobility on the track and an auxiliary undercarriage associated with each main undercarriage and arranged adjacent thereto. The main undercarriages include driven axles to propel the machine and each auxiliary undercarriage includes a dead axle with two wheels arranged to engage the track rails and an adjustment drive for moving the auxiliary undercarriage for selective engagement of the wheels of the dead axle with the track rails whereby diminishing or increasing portions of the load are transmitted to the track by the dead axles and wheels of the auxiliary undercarriages in dependence of the movement of the auxiliary undercarriages into the selected engagement and the load transmitted by the associated main undercarriages is correspondingly increased or diminished by operation of a control for the adjustment drives.
