ABSTRACT:
A device for lifting and/or lining railroad track, which device extends longitudinally of the track and is mounted at one end on a truck carrying track engaging wheels, and the other end is adapted to be connected to a propelling vehicle. Reaction blocks are provided on the beam in the region of the other end, and a track position correcting frame is carried between the reaction blocks and the end mounted on the truck and close to the other beam end. The device provides a lifting and/or aligning attachment for, say a tamping machine, which attachment substantially absorbs all its own lifting and/or lining forces and transmits them to the track rather than to the tamping machine. The device also provides a track position reference means to provide information on the displacement of the lifted and/or aligned track.
