Beschreibung
Zusammenfassung:	The invention relates to a machine for stabilising a track with a ballast bed, comprising a machine frame supported on rail-based running gears and a stabilising unit which can be rolled on rails of the track by means of work unit rollers, and which comprises a vibration exciter for generating a dynamic impact force as well as a loading device for generating a load acting on the track. Therein, the loading device is coupled with a control device for periodically changing the load during a stabilising process. The periodic change of the load alternately influences the near and far range of the load application. This leads to improved compaction effectiveness compared to a constant load.
