<p>System for recovering energy in apparatuses for handling loads wherein a load (2) is vertically moved by means of motor means (M) that, in relation to the operative state thereof, absorbs electric energy in a greater or smaller quantity that a preset value. The system comprises sensing means of the energy instant-by-instant absorbed by the said motor means (M), at least one electric energy generator (G) apt to transform into electric energy the rotation of a shaft (6m) presented by the said motor (M). The sensing means operate the activation of said at least one generator (G) when the energy absorbed by the motor (M) is less than a preset value and operate the deactivation of the said at least one generator (G) when the energy absorbed by the motor (M) is greater than the preset value.</p> |
