[0002] Currently, catwalks serve as the most important high-altitude working passages and temporary work sites for the construction of suspension bridge superstructures. Their alignment is parallel to the main cable alignment, and construction workers use them to complete important tasks such as cable strand pulling, cable adjustment, and cable strand placement. In construction environments with complex wind fields, such as fjords, the catwalk's wind-resistant stability directly determines the safety and quality of construction.

However, the installation of the wind-resistant cables requires the installation of an additional cableway, which is difficult and costly to construct, and the installation of a transverse skybridge is not applicable to situations where the main cables are closely spaced.
