"The world's first beam" Wuchang Shipyard successfully launched

Yesterday, a steel box girder with a weight of more than 1,300 tons was successfully launched at Wuchang Shipyard. According to martial arts experts, this tonnage single-section steel box girder is very rare in the history of world bridge construction, and it is called "the world's first beam." This steel box girder is prepared for the widening of the Chongqing Shibanpo Yangtze River Bridge. Because it was big and heavy, it could not find the means of transportation. The builder installed the "owner" in its head, and installed the signal lights and tethers required for navigation on the upper part, turning it into a "ship" and transporting itself. Today, the Big Mac will be shipped from Wuhan and will arrive in Chongqing about 20 days later.
