This technology features a safety hook device with a pair of opposing, pivoting semi-ring hooks at the ends of tong-like grips, allowing for easy attachment and detachment from scaffolding with a simple squeezing motion. A safety mechanism locks the hooks to prevent accidental opening, while a remote control unit allows for easy release.
While high-altitude workers are required to use safety harnesses and hooks, complex steel structures with intersecting railings and scaffolding often hinder movement, reducing efficiency. Workers frequently have to manually detach and reattach hooks at every support point, creating a safety gap where they are temporarily unsecured.
This technology uses a guide pin on the first handlebar that fits into a slot on the operating body, held in place by an elastic element to prevent the hook from opening. When the control unit presses the protruding piece, the pin shifts into a curved slot, allowing the hook to open. A control rope connected to the handle allows for remote release, while an interlocking insert and receiver prevent the hooks from twisting. Ideal for construction, plant, and shipyard work, this system allows workers to alternate between two hooks, ensuring they remain secured at all times and eliminating fall risks.
