Track-dismantling Machine

Track-dismantling Machine

 

a machine for dismantling old units of rails and ties removed from a railroad line. Track-dismantling machines are used to dismantle units with wooden ties. The main elements of such a machine are a stripping stand for separating ties from rails and backing from ties. Some track-dismantling machines move from tie to tie along the tracks of the railroad being dismantled, tearing up each tie; in other types, the track moves along the machine. The latter type is more widely used and productive and has automatic regulation. In the part that receives units of track, the track is suspended on guide rollers and fed to a brush drum, where ballast is removed from the ties, and is then delivered to the stripping stand. The backing and spikes go into bins, the ties are placed on a chain conveyor for sorting, and the rails, after coming from the stand, are stacked in piles by winches. A track-dismantling machine can process 0.2–0.3 km of track per hour.
