The invention relates to the field of transport engineering, namely for the construction of freight vehicles with devices to facilitate loading and unloading and stowage of cargo.Widely known cargo onboard the vehicle, Obradovic", 1989, S. 45, Fig. 6).This design is simple and allows both the loading and unloading of cargo, but it is necessary that the initial cargo elements, and the process of unloading a long time. Additionally, when the carriage of bulk cargoes require the use of stationary overturning the vehicle mechanisms.A known design of a dump truck containing pivotally connected with the chassis of the tipping body and tilting the device in the form of a cylinder (USSR author's certificate 550305, B 60 P 1/16, 1977).This car provides a fast discharge, however, has limitations regarding the transportation of cargo (mostly dry) and does not possess the capability to carry out its loading.It is also known tipper vehicle with a removable platform, equipped with an engagement element in the form of staples, which interacts l-shaped tripper and removal of the platform from the cylinders (USSR author's certificate N 914347, B 60 P 1/64, 1982).This car can work with various bodies, including the truck, Autonomous replaces the platform, however, requires Speciale close to the claimed device is a cargo vehicle, containing a chassis on which is mounted for tilting the body to accommodate cargo, equipped with initial devices: crane with removable lifting equipment, a gripping element which is arranged to mesh with initial devices body (USSR author's certificate N 1703514, B 60 P 1/64, 1992).This vehicle has the versatility, but structurally difficult - has an additional frame, the tilting device, the tilting actuator device includes a power cylinder and crane. In addition, in the mode dump of the power cylinder is forced to raise together with the body and the crane, it is impossible to ensure tripartite unloading, and when lifting demountables last considerably leans that imposes additional requirements to the goods and bodywork (the need to strengthen the front and rear sides, partitions and so on).The technical result of the invention is to simplify the design.The technical result is achieved by the fact that in the cargo transport vehicle containing the chassis, that is: crane with removable lifting equipment, gripping element which is arranged to mesh with initial adaptations of the body, the base of the boom of the crane arm fixedly mounted on said chassis, a body hinged to the chassis of the vehicle, and an engagement device is placed on the side of the body opposite its hinged connection with the chassis of the vehicle to ensure tipping body.In addition, a body connected to the vehicle chassis by means of a detachable hinge for removal of the body from the chassis of the vehicle in a complete separation of the swivel body with the specified chassis.In addition, initial fixtures placed on a sliding console for their accommodation for the body size.In addition, the body is made of composite, each of which is equipped with original accessories and pivotally connected with the chassis of the vehicle.In Fig. 1 shows a General view of the cargo vehicle;
in Fig. 2 - the same, rear view in the transport position;
in Fig. 3 - freight vehicle mode tipper tipping;
in Fig. 4 - the same, an option with a side unloading and nominated cha is a of Fig. 6 - the same, with side discharge, rear view;
in Fig. 7 - freight vehicle mode demountables;
in Fig. 8 is the same, rear view.Cargo vehicle includes a chassis 1, which by means of a detachable hinge 2 is a rear wheel drive 3 in the form of an airborne platform with initial devices 4. On the chassis 1 is also fixedly mounted on its base by the arrow crane 5 with built gripping element 6 and a set of interchangeable load handling equipment (including grapple, etc). Initial devices 4 are located on the side of the body 3, opposite its hinged connection with the chassis of the vehicle to ensure tipping body (Fig. 1, 3 and 5), and can be placed on a sliding console 7 for their placement for body size (Fig. 4), and the body 3 may be made of composite (Fig. 5 to 8), each of which is made in the form of 8 modules, each of which is pivotally mounted on the chassis 1 and is equipped with original accessories.The proposed vehicle is as follows.Loading is carried out through our own crane 5 or extraneous loading tool. For the convenience of the works of the fid and fixation of detachable hinges 2.In dump mode for tilting the body in the position of crumble cargo reteplase hinges 2 fixation body, except those that are loading side, the crane is 5 its gripping element 6 is engaged with an engagement devices 4 of the body 3 located on the side opposite to the discharge, and picks it up. The body 3 or one of its modules 8 is rotated around prescaling hinges, the burden falls on the ground. Lowering the boom of the crane 5, the body 3 is provided in the transport position. When the lateral unloading to increase shoulder tipping before lifting body initial device 4 is put forward on the console 7 for the overall width of the vehicle.Mode demountables empty or loaded body 3 or one of its modules 8 completely unlinked to the chassis 1, and through the boom of the crane 5 is removed from it and transferred to the right place. 1. Cargo vehicle, comprising a chassis on which is mounted for tilting the body to accommodate cargo, equipped with initial devices: crane with removable lifting equipment, sahwat is, the base of the boom of the crane arm fixedly mounted on said chassis, a body hinged to the chassis of the vehicle, and an engagement device is placed on the side of the body opposite its hinged connection with the chassis of the vehicle to ensure tipping body.2.
