Ballast plow is a kind of equipment that can easily adjust the distribution of ballast in the track. The Angle and direction of opening and closing can be adjusted on both sides of the plow plate. By adjusting the opening and closing direction of the plow plate on both sides, the plow plate can be extended to expand the scope of operation, and the Angle of slope can be changed quickly. Therefore, the equipment can not only repair the roadbed slope, but also smoothly repair the horizontal shoulder pedestrian path.
