A TRAVELLING TRACK TAMPING MACHINE, MORE PARTICULARLY A TRACK TAMPING, LEVELLING AND LINING MACHINE

摘要

A mobile track switch leveling, lining and tamping machine comprises an elongated machine frame, two undercarriages spaced apart in the direction of elongation of the machine frame and supporting the machine frame for mobility on the track in an operating direction, and a respective carrier frame associated with each one of the track rails between the two undercarriages. Each carrier frame supports a tamping tool unit comprising tamping tools capable of tamping the ballast in a track switch, and a track leveling and lining unit comprising tools for lifting and laterally moving the track, the tools being capable of engaging the associated track rail in the track switch, the track leveling and lining unit preceding the tamping tool unit in the operating direction. A longitudinally adjustable coupling device pivotally links one end of each carrier frame to the elongated machine frame, and a free steering gear with a single guide wheel supports an end of each carrier frame opposite to the one end on the associated track rail.
