Description

Technical Field

[0001] The invention relates to the technical field of lifting stages, in particular to a lifting stage protective structure. Background Art

[0002] The lifting stage is a stage equipment that can adjust the height according to the needs of the stage performance. It is usually controlled by a drive device such as a motor, hydraulic system or screw, which can achieve a smooth and precise lifting and lowering of the stage height. Lifting stages are widely used in various performance venues, such as theaters, concert halls, conference centers and various event venues. The design of the lifting stage usually takes into account the needs of the stage performance. The height can be adjusted according to the type of program and the venue environment of the stage performance, making the performance more vivid and diverse. The lifting stage can not only enhance the performance effect, but also facilitate the movement and operation of actors and staff on the stage. At the same time, the stage height can be adjusted according to the needs of different scenes, bringing a better viewing experience to the audience. In general, the lifting stage is one of the important equipment that is indispensable for modern stage performances.
