An emergency device for electric motors 11 of electrohydraulic apparatuses and electromechanical actuators is realised by arranging a connection seat for a drill 13 powered by compressed air, batteries or electricity at the end of the axis of the electric motor 15, which is opposite the side connected to the hydraulic pump or to the geared motor of an electrohydraulic or electromechanical power unit 12 in such a way, in the case of a lack of electrical energy, the drill 13 is able to make the motor 11 rotate, thus actuating the mechanism of the electrohydraulic or electromechanical power unit 12. |
