ABSTRACT:
A mobile machine for leveling, lining and tamping a track has a main frame supported on undercarriages for continuous movement in an operating direction, a power plant and operating controls carried by the main frame, and an elongated subframe pivotally and longitudinally adjustably connected to the main frame, the subframe having two ends and being arranged ahead of one of the undercarriages supporting the main frame, respective undercarriages supporting the subframe ends. Tamping heads are mounted on the subframe between the respective undercarriages for tamping ballast in intermittent tamping cycles under respective ties at points of intersection of the two rails and the respective ties. A track lifting and lining unit is associated with the two rails mounted on the subframe ahead of the tamping heads and arranged on the subframe between the respective undercarriages. A longitudinally adjustable coupling device pivotally connects the elongated subframe to the main frame whereby the subframe moves with the main frame while being longitudinally adjusted in relation thereto.
