Abstract
The invention relates to a method for treatment of a ballast track by means of track maintenance machine which comprises a lifting unit, having gripping rollers for gripping a track grid formed of rails and sleepers and lifting drives for lifting the track grid, and a measuring system for comparing to a target position of the track, wherein the lifting unit is set in vibration by means of a vibration exciter and the vibration is transmitted to the track grid, wherein the lifting unit is controlled by means of a control device in such a way that, during a lifting operation, the lifting unit is set in vibration, and the track grid is first lifted to above the target position and subsequently lowered to the target position. By means of the method according to the invention it is possible to carry out in a simple manner a lifting of the track grid with simultaneous stabilization of the track position.
