FIELD: engines and pumps. ^ SUBSTANCE: invention is related to municipal engineering, in particular, to trucks for assembly and removal of solid domestic waste. Dumptruck of closed type comprises a frame and a manipulator with hydraulic drive. Hydraulic drive comprises a pump, a hydraulic reservoir, a hydraulic cylinders of boom lifting (C3) and container inclination and tracking hydraulic cylinder (C1). Piston and stem cavities of container lifting hydraulic cylinder are connected accordingly with piston and stem cavities of tracking hydraulic cylinder via hydraulic valve with hydraulic control, which connects cavities of tracking hydraulic cylinder and hydraulic cylinder of container inclination during supply of control flow into hydraulic cylinder of boom lifting. Tracking hydraulic cylinder is fixed in diagonal of hinged four-link chain, free tops of which are fixed in boom and frame of manipulator. ^ EFFECT: invention increases reliability of dumptruck, efficiency of loading process with simultaneous improvement of process ecological compatibility. ^ 5 dwg |
