MOBILE TRACK LEVELING, LINING AND TAMPING MACHINE

摘要

MOBILE TRACK LEVELING, LINING AND TAMPING MACHINE A mobile track leveling, lining and tamping machine has a machine frame supported on undercarriages for continuous movement in an operating direction, a power plant and operating controls carried by the machine frame, a tool carrier frame having a front end and a rear end, and an undercarriage supporting and guiding the tool carrier frame rear end on the track. Tamping tool assemblies are mounted on the tool carrier frame immediately ahead of the undercarriage supporting and guiding the tool carrier frame rear end for tamping ballast in intermittent tamping cycles under respective ties at points of intersection of the two rails and the ties in tangent and switch track sections and a track lifting and lining unit is associated with the two rails mounted on the tool carrier frame ahead of the tamping tool assemblies and is arranged on the tool carrier frame between two undercarriages spaced in the direction of the track for lifting and lining the track in tangent and switch track sections. A longitudinally adjustable coupling device pivotally links the front end of the tool carrier frame to the machine frame, the tool carrier frame having a lateral pivoting range sufficient to pivot and guide the tool carrier frame in switch track sections.
