Hopper-doser VPM-770 project 770.00.000

Hopper-doser is designed for transportation on railways of 1520 mm gauge all kinds of ballast (crushed stone, gravel, gravel-sand mixture, granite sift, etc.), not requiring protection from the atmosphere.), not requiring protection from atmospheric precipitation with grain size from 5 mm to 70 mm, its mechanised unloading with simultaneous laying on the track, with dosing and leveling on the track grid, with the possibility of interrupting the process of ballast unloading and limiting its backfilling in the middle of the track. Hopper-doser VPM-770 is also designed for transportation and mechanised unloading of expanded claydite.
