In other words, when a malfunction occurs due to an overload on the driving motor, the safety device for controlling the winding and winding operation of the wire rope in the winding drum is not provided, so the installation frame falls without any restrictions.

In addition, there was a problem in that the wire rope was detached from the guide wheel in the process of being wound around the winding drum, causing malfunction of the stage facilities.

That is, in the process of winding a plurality of wire ropes concentratedly connected by a guide wheel to the winding drum, the guide wheel rotates only at the same position, but the wire rope wound around the winding drum moves along the spiral direction so that the wire rope is diagonally wound. It is because it is bent in the direction.

In addition, the stage device barton 30 is connected to a plurality of wire ropes (L) to maintain the level, but the length between the wire ropes must be adjusted horizontally for a long use, but in the conventional device, the wire tension adjustment barton wire rope The length is very inconvenient because it is vertically connected to (L).

In addition, the stage device baton 30 is simply fixed and stored in the pulley installed at the upper portion by the tension of the wire rope L after use, so that even if there is a small change in the external environment, there is a possibility of shaking or falling.
