A self-propelled ballast cleaning machine comprises a machine frame comprised of two frame parts having abutting ends. A pivotal connection is arranged between the abutting frame part ends to enable pivotal movement of the frame parts in vertical and horizontal directions, and hydraulic drives interconnect the abutting frame part ends to effectuate the pivotal movement in at least one direction. Three track-bound undercarriages respectively support the machine frame at the abutting frame part ends and the ends of the frame parts remote from the abutting ends. Mounted on the machine frame are a ballast excavation chain comprising a horizontal course immersible in the ballast below the track, a ballast screening mechanism for cleaning the ballast coming from the excavation chain, respective conveyors for redistributing the cleaned ballast and for removing the waste respectively coming from the ballast screening mechanism, and a track raising mechanism in the range of the horizontal course of the ballast excavating chain. |
