The invention discloses a real-time balance weight adjusting device for an elevator and a controlling method of the real-time balance weight adjusting device. The real-time balance weight adjusting device comprises a lift car moving vertically; a plurality of gravity sensors are arranged in a bottom plate of the lift car; a supporting plate is arranged on the lower end face of the lift car, and a bearing is embedded in a through hole of the supporting plate; a lead screw is arranged in an inner ring of the bearing, a nut of the lead screw is connected with a balance weight block, and the lead screw is driven by a driving motor; and the driving motor and the gravity sensors are all connected with a PLC controlling circuit in a controlling cabinet. The controlling method of the real-time balance weight adjusting device for the elevator comprises the steps of entering the elevator, judging unbalance loading, calculating the movement amount of the balance weight block, driving the balance weight block to the corresponding position through a driving mechanism and enabling the elevator to operate normally. The real-time balance weight adjusting device is simple in structure, strong in adaptability and convenient to operate. In addition, the service life of the elevator is effectively prolonged, and the using safety coefficient of the elevator is improved.
