ABSTRACT:
The tamping machine has two tamping units (2,3) which are inclinable transversely to the track in order to tamp the track switches.
Each of these tamping units is articulated at its upper part on a slide (18) which is displaced by a cylinder-piston unit (19) on a transverse slideway (16) fastened on a rigid frame (6). This frame is mounted for pivoting around a vertical axis (X) on two brackets (7, 8) fastened to the frame (1) of the tamping machine.
The inclination of each tamping unit is coordinated with its translation on the slideway (16) by a rod (32) which connects an element (30) of the tamping unit to the chassis (1) so as to reduce the differences in tamping depth caused by the transverse displacement of the tools (25).
The lower portion of the tamping units comprises an arm (34) engaged in a curved slideway (23) fastened to the frame (6) in order to transmit the longitudinal tamping forces to the latter.
