Background technique

Safety ropes are often used in high-altitude operations. The operator hangs the safety belt hook on the safety rope for work or walking, which plays a role in safety protection. For the needs of safety and installation, the safety rope needs to be rooted and fixed every few meters. The rooting is usually fixed directly to the external structure by welding or bolts. The safety belt hook hanging on the safety rope cannot directly pass through these rooting points. The hook must be picked and passed over the rooting anchor point before hooking. If you walk along a safety rope that is tens of meters or even hundreds of meters long, you need to remove the hook and hook once for a few meters, and twice for double-hook safety belts. Another situation is that two operators use the safety belt hook to walk toward each other along the safety rope.
