The invention relates to an energy-saving type mechanical lifting electromagnetic lifter which comprises a lifter body. A bracket drive motor is arranged on one side of the lifter body, and a supporting frame drive motor is arranged on the other side of the lifter body. An output shaft of the bracket drive motor is connected with an L-shaped rotary bracket. An output shaft of the supporting frame drive motor is connected with a rotary supporting frame corresponding to the rotary bracket. The lifter body comprises an electromagnetic coil arranged inside and a PLC controller electrically connected with the electromagnetic coil. The PLC controller is further electrically connected with the bracket drive motor, the supporting frame drive motor, a distance sensor and proximity switches. The energy-saving type mechanical lifting electromagnetic lifter has the beneficial effects that energy saving, safety and reliability are achieved; in the lifting process, blank falling cannot happen even though electric control cabinet breakdown or a power supply problem exists; the self weight is reduced, and cost is reduced; the service life is longer; a power failure magnet keeping system is simplified; the cost and space occupied by a storage battery are reduced; and the number of electromagnets needed for lifting is reduced.
