FIELD: mining.
SUBSTANCE: transportation of rock mass from a quarry to a processing plant used in the transportation of highly moistened, sticking and freezing rock masses, as well as radioactive materials. A mobile vehicle with a covering of the bottom (2) and sides (3, 4) of the body (1) includes a bottom (2), above which and above the rotary sides (3) there is a main flexible tape with open ends attached to drive drums with the possibility of winding in rolls, tape supporting rollers and cleaning devices. The side edges of the stationary sides (4) are equipped with additional drive drums with additional flexible tapes attached to them with the possibility of winding them into a roll. Additional drive drums are suspended above the surface of the main belt vertically on support bearing units mounted on the upper edges of the stationary sides.
EFFECT: protecting the internal surfaces of side-dump cars, prevents sticking and freezing of rock mass, eliminates its contact with the bottom and sides of a moving vehicle and ensures complete unloading of the body.
