A method of maintaining horizontal balance at batten elevation is provided to rapidly respond failure of an elevator or difference of motor rotational speed, and to keep right and left slope angles of the batten in horizontal condition and to stably elevate subjects mounted on the batten by adopting principal structure of plural elevators and wireless remote controller to actuate the elevators. The batten elevational device comprises: a main body(140) hanged on a ceiling of a constructional building; a winding wire(130) to raise or drop down a batten in a drum(120) rotational direction; a plurality of elevators(100) that are mounted on the batten at constant intervals and includes a reversible motor(110) for rotating the drum to roll up and release the wire from the drum; and a wireless remote controller(300) to operate the elevators to raise or drop down the batten. The balancing method includes the steps of: transmitting data for instant condition of the elevators after inputting signals for raising or dropping down the batten; and stopping the elevators or sending correction order when abnormal signals are transmitted from one of the elevators to maintain horizontal balance of the batten. |
