Stage electric hoists play a crucial role in creating a magnificent stage: Diversified Presentation of Stage Elements Set Construction and Transformation: They can lift large - scale set materials such as palaces and castles onto the stage for assembly and fixation. During the performance, the sets can be quickly changed according to the plot. For example, in a historical drama, the stage electric hoists can rapidly replace sets with different dynasty - style designs, bringing a more wonderful visual experience to the audience. Prop Lifting and Lowering: The lifting speed and height of special props like flying props and lifting platforms can be controlled. For instance, in a magic show, the precise control of prop lifting and lowering by electric hoists creates a mysterious and fantastic effect. In a mythological play, they help actors achieve a magical entrance effect with the aid of lifting platforms. Lighting and Audio Equipment Adjustment: They can accurately adjust the position of lighting equipment, enabling the lights to better match the performance scenes and atmosphere. They can also hoist and adjust the position of audio equipment to ensure the best presentation of audio effects. Enhancing the Visual Effect of Stage Performances Creating a Sense of Space: Through the lifting and movement of suspenders, a well - structured sense of stage space is ingeniously created, making the audience seem to be in a multi - dimensional art world. For example, in a large - scale musical, the electric hoists are used to arrange stage props and actors at different levels in a scattered way, increasing the three - dimensionality of the stage. Cooperating with Lighting Special Effects: Integrating with lighting special effects to create dynamic visual effects. For example, the British Kinesys CNC hoist, in G.E.M. Tang's "Time Meets Us" concert tour, worked with lighting special effects to give a more three - dimensional expression to the song performance. The circular frame above the head, equipped with effect lights, created a dynamic "spark" lighting visual effect. Ensuring the Safety and Smoothness of Stage Performances Safety Protection Functions: They are equipped with overload protection devices that can automatically stop working to avoid over - load operation. The clutch is integrated on the rotor shaft, using dry - type clutch friction plates. Even after the clutch wears out, it will not slip, ensuring safety. There are also safety designs such as 100 - grade chains, an 8 - fold safety factor, a 360 - degree rotatable hook and anti - decoupling design, and maintenance - free electromagnetic brakes. For example, in large - scale performances, even in case of unexpected situations, these safety devices can ensure the safety of equipment and personnel. Stable Operation: Using high - quality materials and advanced manufacturing techniques, they operate smoothly, reducing the shaking when lifting objects. Precise positioning becomes very simple and convenient for management, thus ensuring the smoothness of stage performances and preventing interruptions due to equipment failures. Optimizing the Audience's Audio - Visual Experience Visual Aspect: A special paint is used, which is basically all - black. It can blend in with the stage background. At the same time, this material has the characteristic of diffuse reflection, and there will be no specular reflection of light affecting the viewing experience, allowing the audience to focus all their attention on the center of the stage.

Auditory Aspect: They have a noise - reduction function. By using technologies such as helical gear transmission, the noise generated during gear transmission and chain output is reduced. During operation, no obvious noise is emitted, ensuring that the audience has a good auditory enjoyment.
