Mechanism for lifting large weights, particularly installable in the boxes of trucks or collector units of various products in order to raise a container from the ground to a determined point of the upper part of said boxes, characterized by the fact of essentially comprising two cylinders hydraulics whose bodies are articulated, at their opposite end to that of the outlet of the rod, in individual points of a convenient frame, said points being located at different heights and the lower one of them being in a more advanced position than the other with respect to the load that it has to rise; and characterized in that the end of the shank of the lower cylinder is hingedly connected to the body of the upper cylinder, while the end of the shank of the latter is applied to the load, all operatively arranged to act, first, the bottom of the cylinders that it will raise the other cylinder with the load, which when being at a certain height, will also be elevated by the upper cylinder that will finish placing it at the appropriate height, describing a parabolic curve altogether.
