This device is a safety protection component designed for various lifting equipment. It uses a weight sensor to detect the hook position. When the hook rises to the preset height, it automatically cuts off the hoisting power circuit to prevent collision between the hook and the top of the boom (anti-two block/anti-overwinding), effectively protecting equipment and personnel safety. Built with industrial-grade protection, it withstands harsh outdoor working conditions of construction machinery and is a mandatory core component required by lifting machinery safety regulations.
