Abstract
A tamping tool unit for tamping ballast under a respective one of a succession of ties of a railroad track comprises a frame extending in a longitudinal direction, a pair of tamping tool levers mounted on the frame for pivoting about pivot axes in a plane extending in the longitudinal direction, a reciprocating drive connected to each tamping tool lever for pivoting the tamping tool lever, and a tamping pick at a lower end of each tamping tool lever. A guide on at least one of the tamping tool levers is provided for displacing the tamping pick in a direction extending perpendicularly to the pivot axis of the at least one tamping tool lever, and a fixing device is provided for fixing the tamping pick on the lower tamping tool lever end.
