Study on Cable-climbing Mechanism for Cable-stayed Bridge

Abstract

Developing cable-climbing mechanism with high velocity and large holding force is a major problem in the research of cable inspecting and maintenance robot for cable-stayed bridge, which is very important for bridge safety and beautification. Concerning different operating conditions, this paper presents two sets of engineering prototype including pneumatic worming cable-climbing mechanism and electric running cable-climbing mechanism.After tested in the laboratory, both prototypes were run experimentally on the Xupu and Nanpu Bridge in Shanghai respectively. The results indicate that two cable-climbing mechanism can climb stay cables safely and efficiently.
