The schemes for the unloading of the wagon-dispenser

WAGON-DISPENSER, hopper-dispenser (EN: measuring hopper, scale car; DE: Dosierwagen; FR: wagon-doseur; ES: vagon dosificador; RU: вагон-дозатор) is the railway wagon for the transportation and mechanized unloading, with the simultaneous dosage and leveling of the ballast materials, during the construction and repair of the railway track.

The wagon-dispenser (Figure) has been created on the base of the hopper wagon, namely, of the special wagon of the hopper type, the body of which has the vertical lateral walls, and the sloping frontal walls. The loading of the wagon-hopper is performed at the top, while the unloading is performed at the bottom through the hatches, which are equipped with the unloading-dispensing device. During the unloading and dispensing, the ballast materials may be distributed either throughout the entire width of the ballast prism, or only at the sides of the railway track, at the middle of the track, between the tracks, and along the side of the railway. For the pneumatic control of the dispenser, the compressed air arrives from the compressor, which has been installed onto the locomotive. The quantity of the ballast, which is being unloaded, is from 40 to 1500 cubic metres per 1 kilometre of the track, during the movement with the speed of 3-5 kilometres per hour. Within the USSR, at the open pit mines, there is used the CNII-DV3 four-axle wagon-dispenser, which is having the volume of 40 cubic metres within the body, and the length of 10.87 metres between the axles for the coupling of the automatic railway coupling device.
