Abstract
The installation for the rehabilitation of a ballast bed supporting a track including two rails comprises a first machine, and a second machine, the machines being supported on the track by undercarriages for movement in an operating direction, and the second machine preceding the first machine in the operating direction. A vertically adjustable ballast excavating device is mounted on the first machine for excavating ballast from underneath the track, a first conveyor arrangement is arranged to remove the excavated ballast from the ballast excavating device, a second conveyor arrangement is mounted on the first machine for conveying bulk material, the second conveyor arrangement having a discharge end rearwardly of the ballast excavating device in the operating direction and an input end arranged at an end of the first machine, and a third conveyor arrangement is mounted on the second machine for conveying the bulk material, the input end of the second conveyor arrangement being arranged to receive the bulk material from a discharge end of the third conveyor arrangement. In accordance with the invention, a clearing device is mounted on the second machine, the clearing device comprising a scraping chain for taking up bulk material lying on the track, the scraping chain revolving about a horizontal axis extending transversely to the track and having a discharge end, and an input end of the third conveyor arrangement being arranged under the discharge end of the scraping chain.
