The SANY GJ-1 Overwind Switch is a safety protection device specifically designed for hoisting machinery. By real-time monitoring the hook position, it quickly cuts off the lifting control circuit when the preset limit height is reached, fundamentally preventing accidents such as steel wire rope overwinding, breakage and hook overtopping. It provides reliable protection for equipment and personnel safety. This product is compatible with all series of SANY cranes, crawler cranes, truck cranes and port hoisting equipment, featuring high protection level and strong anti-interference capability to adapt to various complex working conditions.
