The invention discloses a symmetric balance structure of a vertical revolving electric door. The symmetric balance structure is symmetrically provided with a driving mechanism case and a balance mechanism case at intervals. The driving mechanism case is used for accommodating a driving mechanism, the balance mechanism case is used for accommodating a balance mechanism, the driving mechanism and the balance mechanism are respectively connected with a spindle which is arranged on the upper portion of a space between the driving mechanism case and the balance mechanism case, a door row assembly is arranged on the spindle, can be driven by the driving mechanism via the spindle to vertically rotate and can be stably lifted by opposite torque generated by the balance mechanism in rotation procedures, and the opposite torque is balanced with the door row assembly. The symmetric balance structure has the advantages that the magnitude of moment arm of a spring assembly can be changed by the balance mechanism via a spring hanger, accordingly, torque generated by the spring assembly for the spindle is opposite torque which is balanced with torque generated by the door row assembly for the spindle, load on the driving mechanism can be relieved, the symmetric balance structure is favorable for saving the running cost, and the service life of the driving mechanism can be prolonged; the symmetric balance structure is simple, is convenient to mount and machine and can run stably, and the like.
