FIELD: transport; trackless vehicles. SUBSTANCE: specialized vehicle can be easily converted from dump truck into load truck with rigid fastening of body on frame and locking of hydraulic dumping gear This is provided by use of one or more grips connected with locking mechanism of one of truck sides, for instance with tailgate locking mechanism, to rigidly couple body with chassis frame when tailgate is locked and use of dumping gear hydraulic interlock mechanism coupled with high and low pressure lines of device. Control of hydraulic interlock mechanism is coupled with grip and tailgate lock mechanism and, with tailgate locked, blocks delivery of liquid under pressure to hydraulic power members. EFFECT: improved design of dump truck bodies and dumping gears. 2 cl, 4 dwg |
