Electromechanical lifting system (100, 200, 300, 500) of a load comprising: - At least one cylinder (1, 21, 301) comprising a screw (2, 22, 32, 502) connected to the load and configured for descent and ascent translating along its vertical axis Y; - At least one electric motor (3, 23, 33) connected to one extreme portion of the cylinder (1, 21, 301); - Means (4, 24, 34) for transferring the rotational motion imparted by the electric motor (3, 23, 33) into translatory motion of the screw (2, 22, 32, 502). The cylinder (1, 21, 301) comprises a tank (1b, 21b, 301b) filled with a compressible gas and mobile compression means (5, 25, 305) interconnected with one end (2b, 22b, 32b, 502b) of the screw (2, 22, 32, 502) and configured to transfer energy from the vertical translatory motion of the screw (2, 22, 32, 502), when directed towards the tank (1b, 21b, 301b), to the gas accumulating the energy and for transferring the energy from the gas to the vertical translatory motion of the screw (2, 22, 32, 502) when directed in the opposite direction.
