The arms (11, 12) are pivotable by first cylinder units (15) around first pivot axes (14) parallel with the trolley longitudinal direction, and by means of second cylinder units (19) are projectable laterally. A claw component (23) at the outer ends of the telescopic arms by means of a third cylinder unit (25) is pivotable around a second pivot axis (24), which in the claw component normal work position is parallel with the first pivot axis. The claw component is formed to engage with a special rail part, such as a rail foot (28), for the purpose to lift the one end of the rail from the embankment (8) to a position for insertion in guide components on a track vehicle, which is also movable along the railway track (3). |
