#Blue Iron Line #Iron fans, today I will take you to understand the "woodpecker" exclusive to the railway. The Lanzhou-Chongqing Railway passes through the Qinba Mountains, and most of the trains travel in tunnels and bridges, and each bridge is regularly inspected and maintained by railway bridge and tunnel workers. Wearing hard hats and holding inspection hammers, they beat and beat like "woodpeckers" on bridges. Railway bridge and tunnel workers not only have to check the facilities and equipment on the bridge deck, but more often they "hang" themselves, on the bridge pier platform of tens of meters, climbing, lying down, kneeling, etc. are the basic state of their work, in addition to having a strong psychological quality, but also have superb technology. After their meticulous repair, each bridge is in stable condition, ensuring the safety of railway transportation. (Photo: Chen Longbing)
