Track lifting and lining device

摘要

A mobile track leveling and lining machine comprises a frame and a track lifting and lining device which comprises a rigid tool carrier including a pulling member rigidly connected to the carrier, the pulling member having a free end linked to the frame, and two track lifting tools associated with each track rail and spacedly mounted on the tool carrier. A single pair of flanged wheels arranged between the two track lifting tools serves as lining tools and mounts the tool carrier on a common axle for mobility on the track rails. A power-actuated lifting drive is associated with each track rail and links an end of the tool carrier opposite to the frame end for pivotal movement in all directions to the frame, the lifting drives being arranged to lift the track vertically, and a power-actuated lining drive links the tool carrier to the frame and is arranged to move the track in a transverse direction.
