Product Details

In stage performances, the Theatrical Hoist Overload Protection plays a vital role in ensuring safety, and its operation mechanism and safety value are fully demonstrated when hoisting lighting equipment, audio equipment, or other stage props.

CE Certified Stage Electric Hoist

Before the performance, stage technicians accurately calculate the total weight of lighting trusses, LED large screens, audio arrays, etc., based on the equipment list, and accordingly select suitable stage hoists, clarifying their rated load parameters. During the hoisting process, high-precision strain-type or pressure sensors in the Theatrical Hoist Overload Protection system continuously monitor the stress on key components such as slings and hooks, converting mechanical stress into electrical signals that are fed back to the control unit. Once the weight of the hoisted items exceeds the hoist's rated load, the system immediately triggers a multi-level protection mechanism. First, the audible and visual alarm emits a harsh buzzer and flashing red light to warn on-site staff. Simultaneously, the control unit of the Theatrical Hoist Overload Protection quickly cuts off the motor power, and the electromagnetic brake is activated instantaneously, enabling the hoist to emergency brake within 0.5 seconds to prevent the load from continuing to rise or fall. Some high-end stage hoists also feature dual-sensor redundancy design, cross-verifying data to prevent misjudgment or missed detection due to single-sensor failure.
