This is an original factory-equipped wireless anti-overwind protection device for XCMG truck-mounted cranes. It monitors the boom height in real time, triggering an audible-visual alarm and cutting off dangerous movements when the lifting height approaches a critical threshold. This effectively prevents safety accidents such as wire rope breakage due to overwinding and boom damage from overextension, making it a core component for safe lifting operations.

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.

This product is a safety protection device specifically designed for construction machinery. Its core function is to prevent crane hooks from overwinding during ascent, avoiding steel wire rope breakage or equipment damage. Built with a high-strength industrial-grade housing and a precise mechanical trigger structure, it operates reliably in various complex working conditions, making it an essential safety component for cranes, tower cranes, and other lifting equipment.
