Abstract (en)
[origin: US2015211192A1] An apparatus is provided for compacting the ballast bed of a track, comprising a machine frame which is movable on the track with a stabiliser unit which runs on rollers on the track and is equipped with a vibration drive for producing a vibration in a plane parallel to the track. The stabiliser unit is preferably equipped with tension rollers engaging around the rail head. The stabiliser unit is linked in a height-adjustable manner to the machine frame with an adjusting drive and can be moved against the track under load. In order to provide advantageous constructional conditions it is provided that the vibration drive comprises at least one cylinder vibrator which is formed by a hydraulic cylinder and is triggered via a proportional or servo valve.
