Abstract
The invention relates to a process and apparatus for correcting the surface of a railroad track by exerting pressure on the shoulders of the track from both sides thereof by means of vibrating compactors mounted on a vehicle chassis and provided with pressure applying jacks. The ballast is compacted beneath the track which raises it to a desired first track level which may be above the final desired track level, whereafter the track is tamped down to the desired level by means of a force applicator which imparts pulsating force to depress the raised track.
Claims11
A process for reconstituting the structure and the surface of a railroad track by exerting pressure continuously adjacent the ends of the ties, substantially transversely thereof, to a degree sufficient to displace the ballast beneath the track, the ballast displacement being substantially the sole means to raise the track to a first level and align the track.
A process for reconstituting the structure and the surface of a railroad track by exerting pressure continuously on the shoulders of the track substantially transversely thereof, to a degree sufficient to displace the ballast beneath the track, the ballast displacement being substantially the sole means to raise the track to a first level and to align the track.
Apparatus for reconstituting the structure and the surface of a railroad track comprising a track maintenance vehicle having a frame;
- compacting means mounted on the vehicle;
- pressure exerting means mounted between said frame and said compacting means for exerting through the compacting means a continuous inwardly directed pressure independently on each side of the track adjacent the tie ends substantially transversely and from opposite sides of the track, whereby to displace the ballast and raise and horizontally align the track.
