Concert stage construction using stage electric hoist

　　The main purpose of using stage electric hoists is to achieve rapid conversion of complex scenes and precise suspension of heavy equipment. These electric hoists can carry huge weights, ensuring that lighting, audio equipment, and stage scenery can be safely and smoothly moved to designated positions. When a concert requires quick changes in background video or lighting effects between different songs, the powerful function of electric hoists can come in handy. They can seamlessly switch scenes, avoiding long periods of darkness or idle time, thus maintaining the audience's viewing experience.

　　Stage electric hoists are particularly suitable for building multi-level and dynamically changing stages. In some international large-scale tours, designers often use electric hoists to create unique stage effects, such as suspended stages, moving platforms, etc., which greatly enrich the visual impact and artistic expression of the performance. The precise control capability of the electric hoist ensures the smooth implementation of these difficult designs, while also ensuring the safety of the performers.

　　The application of stage electric hoists in concert stage construction showcases a perfect combination of modern technology and art. It not only improves construction efficiency and reduces labor intensity, but also promotes the development of music performance art to a higher level.

　　Working principle and operation steps of stage electric hoist

　　1. When the power is turned on, the electric motor starts to rotate, and the high-speed shaft of the reducer connected through the elastic coupling also rotates accordingly.

　　2. The driving torque of the electric motor is transmitted to the last stage gear of the reducer through gears, and then connected to the hollow shaft through splines.

　　3. The hollow shaft is further connected to the drum through splines, allowing the drum to rotate under the action of torque.

　　4. As the drum rotates, the steel wire rope begins to wrap or release, thereby achieving the lifting action of the hook and the suspended object.

　　5. In order to ensure the safety of operation, stage electric hoists are usually equipped with multiple protective measures such as limit switches and dual brake systems to prevent safety risks when the chain exceeds or exceeds the weight limit.

　　6. When moving the suspended object to the designated position, the running trolley will walk along the lower edge of the I-beam, driven by an electric motor to drive the wheels on both sides of the trolley. At the same time, the electromagnetic brake on the lifting mechanism will prevent the heavy object from falling, ensuring smooth movement.
