Abstract
The tamping machine is equipped with tamping units having tools (4) intended to be used for tamping both on the open track and of the switch gear. These tools are mounted on a frame (7) which is mounted for vertical movement in a gantry (8) suspended from the chassis (1) of the tamping machine by a double articulation (13, 14, 15), imparting to this gantry a transverse and longitudinal pendulum mobility with respect to the track. In order to be able to adapt the length of the compacting effected by the tools (4) in their two uses, each of these tools has two interchangeable lockable work configurations, one of which is formed of a single pick (22, FIG. 2) for the tamping of the switches and the other of which is formed of two picks (21, 22, FIG. 3) juxtaposed in the transverse direction of the track, for the tamping of the open track.
