ABSTRACT:
A device for rerailing a tool frame having first and second flange wheels onto the rails of a track, the tool frame being movably connected to a machine frame of a track laying machine, the rerailing device comprising a pair of levers mounted directly on the tool frame for abutting against the rails, a swivel drive for swivelling the first and second levers in a plane extending perpendicular to the longitudinal direction of the track, and a spreading drive connected to the tool frame capable of assuming a blocking position in which the position of the tool frame is fixed and a floating position in which the position of the tool frame is adjustable. The rerailing device further comprises a two-stage height drive for lowering the tool frame from the machine frame in a first stage wherein the first and second levers and the swivel drive cause the tool frame to be centered between the rails, and in a second stage wherein, after the tool frame has been centered between the rails, the flange wheels are lowered onto the rails.
