Abstract

<p>The stay-cables of cable-stayed bridges and extradosed bridges being located at relatively large heights, there are many places where visual inspection is difficult because it requires aerial work vehicle for close visual inspection or rope access technology. Further, the high-strength steel wire used for stay-cables is at risk of corrosion due to penetration of degrading agents or the like, as well as fatigue rupture caused by stress fluctuation, but inspection for damage of such steel in protective pipes requires effective non-destructive inspection equipment. This paper describes a self-propelled diagonal member inspection device developed to allow the visual inspection of diagonal members in high locations and the detection of damage in high-strength steel members.</p>
