A standard hydraulic mechanism of lifting and transfer of vehicles that is positioned on the back cantilever of the vehicles. The hauling mechanism consists of a main frame in which an extension is drawn inside and out, through a hydraulic bottle. On the end of the extension through a pin folded footings are adjusted by the potential of motion to the left and to the right so that the rotation ispossible. The structure is supported through two pins on the chassis on the back part of each truck. On the front it is supported through two hydraulic bottles on the frame of the vehicle, in order to ensure the lifting and the plunging of the mechanism. On the upper part of the mechanism the spare wheel of the truck is adjusted. All the motions of this mechanism are made in a hydraulic mode through a relevant control that is positioned on the side of the structure in a compartment. There is also the potential all the operations to be made in a wireless mode by the positioning of electric valves in the hydraulic control. |
