Abstract (en)

[origin: EP0616077A1] A tamping machine (1) for the compaction of a railway (2) ballast consists of a machine frame (4), supported on rail running gear, and of a stabilisation assembly (9) connected to said machine frame so as to be adjustable in height. Said stabilisation assembly can be caused to oscillate horizontally as well as vertically with respect to the machine longitudinal direction by means of vibrators (15) and is designed to be able to travel on tracks via flanged rollers (11). The mutual distance of the flanged rollers (11) perpendicularly to the machine longitudinal direction can be varied by means of a spreading drive (13). The latter is designed as a multi-position cylinder comprising a first and a second cylinder tube (22, 23) arranged one behind the other in the axial direction and having respectively a first and a second, double-acting piston rod (24, 25). The latter is connected in an articulated fashion to an adjoining axle (26) of one of the flanged rollers (11) located opposite one another with respect to the axial direction. <IMAGE>
