The invention relates to automobile dumping transport and to road construction. A dump truck 1 comprises a hydrosystem controlled from a cabin, and a movable device for unloading bulk material, which is mounted inside two channels 9 and comprises a bogie 8. On the platform of the bogie 8 hydraulic motors 13 with eccentrics 15 are mounted across the truck longitudinal axis, coaxially connected via elastic couplings 14 and moved by means of telescopic hydrocylinder 29. A device for gradual spreading bulk material comprises a rear board 16, feeder blade 24 and guide devices 19 for bulk material. Since bulk material is dumped at an angle of board lifting equal to an angle of repose or less, the truck stability is increased in unloading dump materials and dumping them during truck movement and the necessity in leveling dumped unloaded material is decreased or there is no need in it at all. |
