[origin: CA2314207A1] A tamping unit (1) for tamping sleepers (2) of a track (3) is equipped wi th tamping tines (17, 18) tiltable about horizontal pivot axes (16) and arrange d in pairs in the transverse direction of the track. These tamping tines are mounted on tw o tamping tool carriers (8, 10), arranged successively with respect to a longitudinal direction extending perpendicularly to the pivot axes (16) and vertically adjustable independently of one another by means of drives (12), and are respectively connected via squeeze drives (14) to vibration drives (13). Mounted on each tamping to ol carrier (8, 10) is an end pair of tamping tines (17), with respect to the longitudinal direction, for immersion in an end sleeper crib (20) and also two pairs of twin tamping tines (18) provided for immersion in a sleeper crib (21) adjacent to the end sleeper crib (20) and for tamping two adjacent sleepers (2). Arranged between the tw o tamping tool carriers (8, 10) is a further, central tamping tool carrier (9) , vertically adjustable independently of them by means of its own drive (12), on which ar e positioned two pairs of twin tamping tines (19) provided for immersion in a central sleeper crib (22), with respect to the longitudinal direction, and squeezabl e apart for tamping two adjacent sleepers (2) simultaneously.
