The invention discloses an anti-swinging, quakeproof and electromagnetic lifting crane. The crane comprises a bridge and an anti-swinging and quakeproof trolley; the bridge is driven by a motor; the anti-swinging and quakeproof trolley moves along the bridge; a first drum is arranged on the anti-swinging and quakeproof trolley; the crane further comprises an anti-shaking lifting tool; the anti-shaking lifting tool comprises a #-shaped rotating frame; a second drum is arranged on the rotating frame; pulleys are arranged on all the bulging surfaces of the rotating frame; four steel wire ropes are arranged among the pulleys, the first drum and the second drum and are intertwined in a forwards, backwards, leftwards and rightwards crossing manner; the rotating frame is restrained correspondingly in the front, back, left and right directions; a rotating motor is arranged in the center of the rotating frame; and a hanging beam rotates on an output shaft of the rotating motor. The crane is simple and reasonable in structure and convenient to use, the four steel wire ropes are arranged among the pulleys, the first drum and the second drum and are intertwined in the forwards, backwards, leftwards and rightwards crossing manner, the rotating frame is restrained correspondingly in the front, back, left and right directions, and the function of preventing shaking in the four directions is realized.
