Abstract
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.
Claims7
A machine for stabilizing a track with ballast bed, comprising:
- a machine frame supported on rail-based undercarriages and
- a stabilizing 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;
- and
- a loading device for generating a load acting on the track, wherein the loading device is coupled with a control device for periodically changing the load during a stabilizing process;
- wherein two stabilizing units arranged one behind the other, each stabilizing unit with its own loading device, are operated together;
- wherein an interval, adjusted to a driving speed of the machine, is predefined for the periodically changed load.
