The mobile track-tamping/levelling/straightening machine (1) comprises a track stabiliser (2) coupled to it. The track stabiliser has a bogie frame (8) carried via two bogies (7). Between the two bogies there are located two track-stabilising apparatuses (9, 10) which each have a vibrator (13) and a tool frame (14, 15). The vibrators are used to vibrate a track section approximately horizontally. For this purpose, the tool frames are connected to the bogie frame via loading apparatuses (11, 12). The flanged wheels, arranged on the tool frame (14, 15), and gripping rollers, which can be laid onto the rails of the track from outside, can both (16) be pressed onto the rails without play by means of a spreading and locking apparatus (17, 18). By means of the spreading and locking apparatus, a force fitting connection for transmitting the vibrations is produced between that part of the tool frame (14, 15) which can move transversely to the track, together with the associated vibrator (13), and the rails. <IMAGE> |
