The stage chain block adopts a pure mechanical structure, requiring no power connection and independent of on-site power supply. It can work normally under conditions such as power failure, no power supply, temporary outdoor sites, remote performance venues, emergency repair and so on. It is not affected by circuit faults, unstable voltage, line damage and other problems, with strong emergency response capability and stable and reliable operation.
It can be used at any time before the performance, during the performance or in case of emergencies, ensuring the normal lifting and positioning of scenery, lighting, sound and other equipment, not delaying the performance progress due to power supply problems, and guaranteeing the safe, stable and uninterrupted operation of the whole event.
