Abstract of the Disclosure A mobile track tamping machine carries equipment for lifting and lining track in switches and crossing. This equipment comprises a power-driven support frame for lifting and lining, the support frame running on each track rail with a pair of flanged wheels whose flanges are arranged for engage- ment with the insides of the rail heads so that the wheels may serve as lining rollers upon lateral movement of the support frame. A lifting tool is mounted on the support frame inter- mediate each pair of flanged wheels and each lifting tool assoc- iated with a respective rail has a hook capable of selectively gripping the rail head and rail base at the outside of the associated track rail upon adjustment of the lifting tool rela- tive to the support frame. A pivot mounts each lifting tool on the support frame, the pivots extending in a direction par- allel to the machine and enabling the lifting hooks to be pivoted in an operating movement in a plane extending transverse- ly and perpendicularly relative to the track. The lifting tools have hooks arranged to move practically rectilinearly during the operating movement of the tools and they have an additional motion relative to the flanged wheels for selectively gripping the rail head and rail base of the associated track rail and any rail clsely adjacent to the outside of one of the track rails in a switch or crossing.
