See full text

A tamping machine for tamping a track is equipped with a track lifting unit, positioned immediately in front of a tamping unit, and an auxiliary lifting device (19) designed for lifting a branch rail (20) of a switch branching off the main track. The auxiliary lifting device (19) is fastened to a beam (21) extending perpendicularly to a longitudinal direction of the machine and has a lifting tool (27) designed to be applied to a rail head (26). Two disk-shaped thrust rollers (32), spaced from one another in the longitudinal direction of the machine and rotatable in a common plane of rotation (33), for application to a first side face (34) of the rail head (26) are connected to the auxiliary lifting device (19). A flanged roller (36) is provided for application to a second side face (35) of the rail head (26) and for resting the auxiliary lifting device (19) on the latter. The auxiliary lifting device (19) is pivotable relative to the beam (21) about an axis (42) by means of a drive (41).
