This technology is a clamp-type safety hook device that connects to a worker's safety lanyard and attaches to structures such as scaffolding. It consists of a pair of clamp units with semi-circular first and second hook parts, a safety operation unit that selectively allows the opening and closing of the hook parts, and an operation unit that opens the hooks when pressed.
In high-altitude work environments, workers have historically faced the inconvenience of manually unhooking and re-hooking their safety gear every time they move, which creates a safety gap where the hook is not properly secured. Additionally, there has been the limitation that safety hooks located out of reach are difficult to release.
This technology allows for easy attachment to scaffolding by gripping it like a pair of tongs, while a safety operation unit—comprising elongated slots, guide pins, and an elastic element—structurally locks the hook to prevent accidental opening after attachment. By applying pressure to the protruding piece via an operation rope, the hook can be released even from a distance, allowing for continuous safety by alternating between a pair of hooks. It can be applied to fall prevention equipment in construction scaffolding, plant facilities, and bridge work, ensuring an uninterrupted fall protection system while moving.
