The machine is intended for the displacement of open track sections and switch gear. For this purpose, it is provided, for each line of rails, with a shifting roller (17), a hook (11) for the lifting of the switch gears and roller (12) for the lifting of the open sections, these tools being mounted on a tool holder (9, 10) moved by lifting (22) and shifting (23) jacks connected to the chassis (3) of the machine. The lifting hook (11) and the lifting roller (12) are mounted movable in rotation in a plane parallel to the track around a shaft (29) and are moved around said shaft by a jack (32) having two end-of-stroke positions corresponding to the operating position of one and the other of these two tools respectively. Other mountings permitting similar effects are described. |
