ABSTRACT:
A system for the fast road transportation of a cumbersome equipment comprises a first plate coupled with a lifting unit and connected by a hydraulic jack to the equipment. Against this plate a second plate is coupled which is provided with two parallel, horizontal and elongated curved slots cooperating with four fixed pins, three of them being placed at the apices of a horizontal base triangle, the fourth being located in the middle of the horizontal base of the triangle. The slots extend as anti-clockwise curved slots, the upper one directed downward, the lower one directed upward and having radiuses equal to the distance of the fourth pin respectively from the apex pin and from the base pin. A further anti-clockwise curved slot is provided directed downward which starts from the lower slot at a distance from its end equal to the double of the distance from the fourth pin to the base pin.
