The stage electric hoist is an important part of stage mechanical equipment and has various important uses in stage performances and related activities, as follows: 1. Hoisting and Positioning of Lighting Equipment    - Height Adjustment: It can precisely lift lighting fixtures, lighting racks, etc. to different heights to meet the requirements for lighting heights in different areas and scenes of the stage. For example, raising the spotlight to an appropriate position to highlight the protagonist on the stage, or lowering the diffused light fixture to create an overall atmosphere.    - Angle Adjustment: In cooperation with other devices, it can achieve fine - tuning of the angles of lighting equipment in the horizontal and vertical directions, enabling the light to be accurately projected onto the required positions on the stage, creating various effects such as follow - spot, side - light, back - light, etc., adding a sense of hierarchy and artistic appeal to the stage performance. 2. Installation and Arrangement of Audio Equipment    - Optimizing Sound Propagation: It can hoist the audio equipment to an appropriate height and position, enabling the sound to propagate and disperse better in the stage space, avoiding sound dead zones and ensuring that the audience can enjoy a good auditory experience in different positions.    - Flexible Layout: Depending on the size, shape of the stage and the form of the performance, the electric hoist can be used to flexibly adjust the hanging positions of the audio equipment. For example, hanging the main speakers at high positions on both sides of the stage and distributing the auxiliary speakers in different areas to achieve all - round sound coverage. 3. Lifting, Lowering and Switching of Stage Curtains    - Scene Transition: During the performance, it is necessary to quickly and accurately switch different curtains to create different scenes. The stage electric hoist can quickly raise or lower the curtain according to the instructions, realizing a seamless transition of scenes and helping the audience better understand the development of the plot.    - Creating Atmosphere: By controlling the lifting speed and height of the curtain, different stage atmospheres can be created. For example, a slowly lowering thick curtain can give a solemn and mysterious feeling, while a quickly rising light - weight curtain may bring a brisk and lively atmosphere. 4. Hoisting and Manipulation of Stage Props    - Display of Large - scale Props: For some large - scale stage props, such as huge prop models, simulated landscapes, etc., the stage electric hoist can provide sufficient force to lift them and stably fix them in the designated positions, creating a realistic scene for the performance and making the audience feel immersive.    - Presentation of Dynamic Effects: It can achieve the dynamic display of props, such as moving and rotating props in the air, adding more visual effects and surprise elements to the stage performance, making the performance more vivid and interesting. 5. Installation and Debugging of Stage Mechanical Devices    - Assisting Large - scale Devices to be Put in Place: During the installation and debugging of stage mechanical devices such as lifting platforms and rotating stages, the stage electric hoist can help accurately hoist these large - scale devices to the predetermined positions, ensuring their installation accuracy and stability, and laying the foundation for their subsequent normal operation.    - Maintenance and Repair: During the maintenance and repair of stage mechanical devices, the electric hoist can conveniently lift or move the parts that need to be repaired, facilitating the operation of the staff, improving the maintenance efficiency, and ensuring the normal operation of the stage equipment. 6. Creation of Special Effects    - Assisting Aerial Performances: In some performances with programs such as trapeze acts and acrobatic shows, the stage electric hoist can, in line with the performance requirements, achieve effects such as actors flying and floating in the air through precise control of speed and position, bringing the audience an exciting visual experience.

   - Realization of Creative Effects: In cooperation with other stage special - effect equipment, the stage electric hoist can also create various unique stage effects, such as simulating the floating of objects, rising and falling clouds, etc., adding more creativity and a sense of fantasy to the stage performance.
