A travelling track tamping machine (1) comprising a machine frame (9) supported by undercarriages (2, 3) and a tool frame (26, 27) mounted to pivot laterally parallel to the plane of the track about a vertical axis (24, 25) and further comprising tamping units which are arranged adjacent one another transversely of the track, being designed for transverse and vertical displacement independently of one another under the power of drives, and which comprise pairs of tamping tools designed to be squeezed and vibrated by drives and incorporating tamping tines designed to penetrate into the ballast. Out of a total of four tamping unit assemblies (14, 15, 16, 17) arranged adjacent one another transversely of the track and designed for independent vertical displacement under the power of their drives - each with a pair of tamping tools with tamping tines designed to penetrate into the ballast on the left or right of one or the other rail (5, 6), the two outer tamping unit assemblies (14, 17) are mounted for transverse displacement with their vertical displacement drives (66) on pivotal tool frames (26, 27) which are designed to pivot laterally relative to the machine frame (9) about vertical axes (24, 25) independently of one another under the power of their own drives (22, 23). <IMAGE> |
