Building bridges in China. Bridge construction. Construction in China

This unique machine was made in China as part of a project to build a railway from Beijing to Inner Mongolia. The total length of the tracks should be about 17,000 kilometers, and, of course, mountains and canyons are encountered along the construction path.

At the same time, the road is designed for high-speed trains that will move at speeds from 250 to 350 km/h. Therefore, the tracks themselves should have as few joints as possible, and the bridges should have sufficiently long sections.

It was for the construction of bridges that the 11th design bureau of the Chinese Railways developed a bridge layer, unpretentiously named SLJ900 / 32. And it was built by Hanjiang Heavy Industries. The number 900 in the name indicates the maximum weight in tons of the bridge segment that this monster is capable of laying. He himself weighs much less - "only" 580 tons.

It is 91.8 meters long, 7.4 meters wide and 9 meters high. Thanks to this size, it can move independently along the tunnels and the road as it is built. Thanks to such an interesting decision of Chinese engineers, the speed and efficiency of bridge construction have increased significantly - greenli, greenli video.
