The present invention relates to a stage facility lifting apparatus having a new structure, which is capable of effectively sensing an operation abnormality due to an abnormality of a wire while having a simple structure. In accordance with the present invention, the stage facility lifting apparatus measures the rotation speed of a wheel body (22) provided in a pulley (20) through a rotation speed sensing means (61) during the driving of a winch (30) and then, when the wheel body (22) becomes slower than the rotation speed of a wheel body (22) of another pulley (20), the control means (50) determines the situation as an abnormality of a wire (31) and drives a warning means (62) to issue a warning to a manager. Therefore, since the manager can quickly identify the occurrence of the abnormality of the wire (31) and perform maintenance work, the apparatus can have prevent an unnecessary load from being exerted to another normal wire (31) or an excessive load from being exerted to the winch (30).

    본 발명은 구조가 간단하면서 와이어의 이상에 따른 작동이상을 효과적으로 감지할 수 있도록 된 새로운 구조의 무대설비 승강장치에 관한 것이다. 본 발명에 따른 무대설비 승강장치는 윈치(30)의 구동시 회전속도감지수단(61)을 이용하여 활차(20)에 구비된 휠본체(22)의 회전속도를 측정하고, 회전속도가 다른 활차(20)에 구비된 휠본체(22)의 회전속도에 비해 낮은 휠본체(22)가 발생될 경우, 상기 제어수단(50)이 와이어(31)에 이상이 있는 것으로 판단하여 경보수단(62)을 구동시켜 관리자에게 경보를 한다. 따라서, 와이어(31)에 이상이 발생된 것을 관리자가 신속하게 파악하여 유지보수함으로써, 정상적인 다른 와이어(31)에 불필요한 부하가 가해지거나 윈치(30)에 과도한 부하가 가해지는 것을 방지할 수 있는 장점이 있다.
