“Examining” bridges is almost on foot. In addition to bridge deck inspection, in most of the examinations, staff need to go through the access channels. Many of the channels are made by iron railings with a diameter of less than 1 meter and they are basically vertical up and down. After inspecting a bridge, the steps of a maintainer can easily “reach ten thousand”. And for they often climb access channels, glove is also one of their necessary tools. 

Cuntan Yangtze River Bridge is a steel box beam single-span suspension bridge. The anchorages on both side are like weights, holding the main cable of the bridge firmly. Zhang Ben and Yan Fuyang get into anchor chamber. Following the flashlight, it can be seen that the main cable penetrates into the anchorage through saddles, and then spreads out 110 strands of cables, which are able to bear the strain from the whole bridge. In the process of maintenance, they carefully examine whether the steel members in anchor chamber are rusted or have other problems.

From the bottom to the top along the anchor chamber, they examine whether the cable strands are rusted or cracked. In spite of the narrow and dark path, they have been very skillful in actions for they have been working here all year round.
