East China's Jiangsu province has stepped up the construction of major investment projects and ensured their smooth progress through every possible effort so as to fulfill goals for social and economic development. JSBC has the story.
The first large section of steel truss girder of the Changzhou-Taixing Yangtze River Bridge was hoisted on Wednesday, marking the start of the erection of the steel truss girder of the main channel bridge.
The four main hooks of a 2500-ton floating crane ship are slowly lifted, and a 1280-ton steel truss beam is stably lifted and accurately placed on a sliding bracket in the air 60 meters high.
The construction of the main channel bridge uses the double main truss "N" steel truss beam, with a truss height of 15.5 meters and a truss center spacing of 35 meters. The whole bridge has 91 large sections, each of which is 14-28m long and weighs about 900t - 1856t.

Today, we welcome the erection of the steel truss girder of the main channel bridge on the site. Next, we will welcome the capping of the world's tallest 352m bridge tower and the connection of the highway and railway steel truss arch bridge that has a main span of 388m. All builders will keep in mind production safety, speed up the project with high efficiency and quality, and make due contributions to the high-quality construction of a powerful transportation country and a strong rich and beautiful high-tech Jiangsu.
