Abstract
A track maintenance machine, constructed to be mobile on a track, for consolidation of a ballast bed underneath a track, includes a machine frame supported on an undercarriage and a consolidating device, connected to the machine frame, which includes at least one consolidating element constructed to be lowered. The consolidating element is constructed as a consolidating plate which, in a working position, is larger in a longitudinal direction of the track than a distance between two sleepers of the track, and the consolidating plate is disposed to be rotatable in order to turn the consolidating plate into a passing position for lowering or raising between two sleepers. A method for consolidation of the ballast bed underneath a track by using a track maintenance machine is also provided.
