Background
With the development of cultural affairs, a plurality of large-scale multifunctional halls, such as theatres, studios, conference halls and the like, are newly built in the society in recent years. The building height of these multi-functional hall designs is lower, and considering pleasing to the eye, the light gallows of performance area configuration adopts aluminum alloy truss mostly, for the circular hawser of lighting apparatus configuration power supply in addition. In the moving process, the light hanging rod rises to a certain position and is hidden in the grid at the top, so that illumination is provided for the multifunctional hall, but the audience cannot perceive the existence of the light hanging frame.
However, in the lifting process of the traditional light hanging bracket, the mooring rope cannot be timely and reasonably stored. For example, during the descending process of the light hanging bracket, the randomly folded cable is easy to hang on other equipment during the stretching process, and further cannot descend normally. In the process of lifting the light hanging bracket, the cable is folded randomly, so that the appearance of the top of the multifunctional hall is easily affected, and potential safety hazards of lines can be brought.
