SYSTEM FOR RECOVERING ENERGY IN APPARATUSES FOR THE HANDLING OF LOADS
First Claim
1. A system for recovering energy in apparatuses for the handling of loads, wherein a load is moved vertically by an electric motor means which, depending on an operative state thereof, adsorbs electric energy whose level is less or more than a preset value, the system comprising:
- a sensing means for sensing a quantity of electric energy instant-by-instant adsorbed by said electric motor means; and
at least one electric generator for converting rotation of an output shaft of said electric motor means into electric energy, said sensing means driving activation of said at least one electric generator when the electric energy adsorbed by said electric motor means is less than a preset value and said sensing means driving the deactivation of said at least one electric generator when the electric energy adsorbed by said electric motor means is greater than said preset value.

Abstract
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.
