As a core safety component of stage electric hoists, the overload protection device can accurately monitor variations in hoisting loads. When the actual load on the equipment exceeds the preset safety percentage of the rated lifting capacity, the built-in high-precision mechanical or electronic overload limiter will immediately activate the protection program, rapidly cut off power output and trigger the braking system synchronously to force the termination of hoisting movements. This fundamentally avoids component damage and structural deformation of the equipment caused by overloading, effectively prevents the occurrence of safety accidents such as hoisting instability and heavy object falling, and safeguards the overall safety of the equipment, personnel and the entire stage site.
