摘要
In a track working machine for removing excess ballast from a ballast bed arranged to support a track defining a plane and for planing the ballast of the bed, which comprises a frame, undercarriages supporting the frame on the track for movement in a working direction, an improved ballast removing and planing device is mounted vertically adjustably on the frame and includes an endless ballast removing chain comprised of a multiplicity of chain members extending substantially parallel to the track plane, two chain reversing points about which the chain is trained for movement in a plane extending substantially vertically to the track plane, and a drive for moving the chain in the vertical plane and having an axis extending substantially parallel to the track plane, the chain having an upper and a lower stringer, the lower stringer facing away from the frame and projecting forwardly of the upper chain stringer in the working direction.
