The invention relates to an elevator device capable of automatically adjusting gravity center balance of an elevator car. The elevator device comprises an electromagnetic swinging device, balance sensors and a controller, wherein the electromagnetic swinging device and the balance sensors are arranged on the elevator car, and the controller is electrically connected with the balance sensors. The electromagnetic swinging device comprises a machine base arranged on the top or the bottom of the elevator car, a rolling body rotationally connected with the machine body, and a shaft rod. One end of the shaft rod is connected with the rolling body, and the other end of the shaft rod is connected with a compensation block. The machine base is provided with magnetic field generating devices electrically connected with the controller. The rolling body is provided with magnetic pieces matched with the magnetic field generating devices. The balance of the elevator car is detected through the balance sensors, information is sent to the controller, and the controller controls the action of the electromagnetic swinging device according to the collected information. The elevator car is kept balance through the controller according to the compensation direction and capacity, friction force between guide shoes and guide rails is reduced, and the comfort level of elevator taking of passengers is improved. Abrasion of the guide rails, steel wire ropes, a tractor, a tractor drive module and other mechanical and electrical components of an elevator is reduced, and the service life of the elevator is prolonged.
