VERFAHREN UND VORRICHTUNG ZUM UNTERSTOPFEN VON SCHWELLEN EINES GLEISES
The invention relates to a method for tamping sleepers of a track by means of a tamping assembly comprising at least two tamping units which have tamping tools lying opposite one another in each case and supported on a lowerable tool carrier, wherein the tamping tools—actuated with a vibration—are lowered into a ballast bed during a tamping operation and squeezed towards one another via squeezing drives. In this, for tamping an obliquely-lying sleeper, the tamping tools or tamping tool pairs in a raised position are moved via a control by means of the squeezing drives in the squeezing direction with different adjustment paths in such a manner that the free ends of the tamping tools or tamping tool pairs rotate approximately about a common vertical rotation axis in order to adapt themselves to the oblique position of the sleeper. With this method according to the invention, the necessity of a separate mechanical rotation device is eliminated.
