Abstract
A tamping unit (5) for simultaneously tamping three sleepers (6) of a track (3) comprises inner, central and outer tamping tools (12, 13). The pivot axis (17) of the inner tamping tool (12) is positioned lower, with respect to the pivot axis (17) of the central tamping tool (13), by a vertically extending distance (a). The longitudinal axes (18) of the two tamping tines (19) are positioned, with regard to the two pivot axes (17) of the inner and central tamping tool (12, 13), off-center and closer to the pivot axis (17) of the inner tamping tool (12). With this, it is possible to also tamp without problems sleepers having a small sleeper crib width.
