Tamping machine for compacting the ballast bed of a track
Abstract:
The invention relates to a tamping machine (1) for compacting the ballast bed of a track (9), comprising tamping units (4) for tamping a track (9), a lifting and lining device (2) for lifting and lining tracks and switches (9), said device being arranged between the running gears (8), preferably in front of the tamping units (4) in the working direction (C), and comprising lifting rollers (6) and lifting hooks (7). In order to provide advantageous conditions it is proposed that the lifting roller (6) with its associated vertical guide (18) and the lifting hook (7) with its associated vertical guide are displaceably mounted along a common transverse guide (16) extending transversely to the longitudinal axis (L) of the tamping machine.
