On the other hand, when setting up the top scaffold and moving operations, the safety rope needs to be loosened. Once the construction workers slip or step on empty space, they will lose safety protection, causing casualties, and bringing major losses and adverse social impacts to the construction project and the construction unit. Therefore, the utility model proposes a scaffolding safety rope hanging device to ensure the safety of workers when working on the scaffold. Utility Model Content
