Abstract
A mechanical device for reducing the energy absorbed by an electric motor of a handling plant. The device includes a first rotating member moved by the motor of the handling plant. The device also includes a second rotating member connected to the first member through a first transmission apparatus. A third rotating member is connected to the second rotating member through a second transmission apparatus, which develops a transmission ratio equal to unity. The device further includes a fourth rotating member operatively connected to the rotor of the electric motor. The fourth rotating member and the third rotating member are connected through a third transmission apparatus, which develops a transmission ratio equal to unity. The device includes a sixth rotating member connected to a fifth rotating member through a fifth transmission apparatus.
