At present, the surface design of the catwalk is generally composed of wire mesh and wooden squares. It is high in height, steep in slope, difficult to walk on, and belongs to high-risk operations. In addition, the catwalk has a significant vibration effect under the action of pulsating wind, which makes it difficult for workers to walk, time-consuming and laborious, prone to fatigue, poor comfort, and low work efficiency. The span of suspension bridges is getting larger and larger. At present, the main span of domestic suspension bridges has exceeded the 2,000-meter mark, and the corresponding catwalk length is also more than 4,000 meters. If it is still designed according to the conventional catwalk, it will take 2 to 3 hours for construction workers to walk on the catwalk once, and 4 to 6 hours if they turn back. The work intensity is extremely high, and the construction efficiency and quality of the workers are difficult to guarantee. For this reason, we propose a manned hanging seat device for the main cable of the suspension bridge to solve the above problems. Utility Model Content
