② Safety auxiliary rope: material is nylon, specification: diameter is 20mm. The tension is about (220000 n). Function: used with main rope. The air height workers hang on the main rope through the seat plate, and connect the self-locking device of the safety belt to the safety rope, which can ensure the improvement of the safety factor.
③ The material is also called as the hanging board when the worker sits on the high-altitude cleaning board, which is called the hanging board.
