<p>A tamping-tool unit (3) consists of two tool-holding devices (20) which are in each case mounted pivotably about an axis (22) running transversely to the longitudinal direction of the machine. These devices are designed as essentially fork-shaped pivot levers with a pivot bearing (23), a forked drive arm (24) extending upwards from the latter, and two side arms (25, 26) extending below the pivot bearing (23) transversely to the longitudinal direction of the machine to opposite sides of the vertical longitudinal plane of the rail. Arranged on the outer side arms (25) are tamping tools which are movable only in the longitudinal direction of the track, intended for submerging in adjacent sleeper compartments and together form a tamping-tool pair (29). In order to be able to avoid track components which are in the way, in particular in the crossing and points region, the tamping-tool pair (30) lying on the inside of the rail is additionally designed to be laterally pivotable about an axis running in the longitudinal direction of the machine. <IMAGE></p> |
