[Abstract]:At 14:00 on November 9, the steel box girder, weighing 272 tons, rose slowly and, under the operation of the constructors, was steadily set up to the predetermined position of the Dashaishui Bridge of the Humen No. 2 Bridge. The successful erection of the first steel box girder of the second Humen Bridge marks that the widest suspension bridge in the world has entered the "building block" stage of the steel box girder, and the superstructure construction will enter the "fast lane". A deck barge carries steel box girder to the bridge of Dashashui Road and is located exactly below the cable clamp No. 46 and 47. Then, under the operation of the constructor, the 600 t fully hydraulic cable crane is connected with the hoist. Hoisting begins formally, cross cable hoisting
