Abstract (en)
[origin: US2004003750A1] A tamping machine for tamping ballast underneath ties of a railroad track includes a machine frame extending in a longitudinal direction and supported for mobility on the track by two undercarriages. A subframe is arranged between the undercarriages and is mobile on the track by means of a further, separate undercarriage. A frame support is provided for connecting the subframe to the machine frame in a manner allowing displacement of the subframe in the longitudinal direction. The frame support is mounted on the machine frame and displaceable relative thereto perpendicularly to the longitudinal direction. A transverse drive is connected to the frame support and linked to the machine frame. A vertically adjustable tamping unit and a track lifting unit are arranged on the subframe between the further undercarriage and the frame support.
