(57) Abstract:Usage: to prevent movement of trucks with neohumanism body. The inventive chassis truck fixed body of the rheostat sensor positioner body. The slider of the rheostat is connected with the body. Additionally, the sensor is designed with additional contacts, closing the electrical circuit electro pneumatic valve connected to the brake system, to activate the braking system of the truck when neopushennaya body. 2 Il. The invention relates to mechanical engineering, in particular vehicles tipper body.Known truck containing a chassis mounted on it can be swung from the actuator body and the positioner body.However, the known truck when unloading is not retarded and the movement with neohumanism body reduces reliability and safety.The aim of the invention is to increase reliability and safety.The aim is achieved in that the sensor index is a rheostat, the body of which is fixed on the chassis and the slide is connected with the body, and the sensor is designed with additional kontaktujte brake system of the truck when neopushennaya body.In Fig.1 shows a truck, General view; Fig.2 - the same, the electric circuit of the positioner body.The truck includes a chassis 1, mounted on it can be swung from the actuator 2, the body 3 and the positioner body 3. The sensor 4 of the pointer represents the rheostat 5, the body of which is fixed on the chassis 1 and the slider 7 is connected with the body 3. The sensor 4 is performed with additional contacts 8 to close the electrical circuit is connected in the brake system electro pneumatic valve 9 to activate the brake system when neopushennaya body 3.When you enable lock 10 ignition switch closes the electrical circuit and the pointer indicates that the body 3 is omitted.When unloading the truck, include drive 2 lifting body 3. The body 3 starts to rise and the slider 7 is moved along the resistor 5 and the pointer indicates the degree of rise of the body 3, for example in degrees. At the same time additional contacts 8 complete the electrical circuit electro pneumatic valve 9, the last perepuskat air from the source 11 to the wheel brakes 12 of the truck and turns on the brake system, eliminating the moving truck when neopushennaya body 3.After unloading the truck lower body 3 in shoddiest and traffic safety truck. The TRUCK containing the chassis, mounted on it can be swung from the actuator body and the positioner body, characterized in that the sensor index is a rheostat, the body of which is fixed on the chassis and the slide is connected with the body, and the sensor is made with extra contacts to close the electrical circuit is connected in the brake system electro pneumatic valve to activate the braking system of the truck when neopushennaya body.

FIELD: transport engineering.
SUBSTANCE: proposed self-dumping trailer has body 2 engaged with dumping hydraulic cylinder 3 with ball support installed stationary in support plate of bracket rigidly connected to crossmembers 8 of frame 1. Support plate consists of two bowls 5 installed with clearance relative to each other, between which ball support of hydraulic cylinder 3 is arranged. Each bowl of support plate is rigidly secured on one of components of structural members 7 of bracket belonging to one of crossmembers of chassis frame. Bowls of support plate are enclosed by lock made in form of resilient lock ring.
EFFECT: improved operation reliability.
FIELD: transport engineering.
SUBSTANCE: invention relates to devices for mechanized unloading of dumpcars and other vehicles. Proposed dumpcar body tilter has body 3 mounted on lower frame 2 for turning in vertical plane and hinge-coupled with power cylinder 4. Rod 5 of power cylinder is hinge-connected with one end of tie-rod 6 whose other end is hinge-connected to lower frame 2. Said tie-rod has two slots 10 for movement relative to joints fastening to lower frame and to rod. Joint of power cylinder rod and tie-rod is attached to body through slot in body.
EFFECT: increased angle of tilting of body, reduced force acting onto body from side of power cylinder rod.
FIELD: machine building.
SUBSTANCE: invention relates to transport machine building, in particular to dumper platform lifting devices. The proposed dumper platform lifting device incorporates pump (1), oil tank (4), control valve (7), adjusting valve (8) and hydraulic cylinder (9). Bode (10) of adjusting valve (8) represents an adapter (13) attached on hydraulic cylinder (9). Control valve (7) communicates with radial channels (12) in body (10) and stepwise axial channel (11) accommodating plunger (15) that features preset diametre central bore (16), the said plunger being pressed to end face (21) of the said stepwise channel by spring (17) entering central channels (18, 19) of plunger (15) and plug (20) screwed in body (10). The compression force of spring (17) can be adjusted. There are adjusting shims (24) fitted between plug (20) and the body. The loaded platform downing deceleration results from shifting plunger (15), by fluid pressure, into space (27) and ingress of fluid via channels (23).
