Builders prepare steel girder cantilever erection at the construction site on the Taizhou side of the main channel bridge of the Changtai Yangtze River Bridge in Taizhou, Jiangsu province, China, Sept 2, 2023. The first pair of steel stringing beams of this suspension hoisting, with a single section length of 28 meters and weight of about 1546 tons, should be lifted synchronically by two bridge floor cranes to 60 meters above the river surface to complete matching and connection with the installed beam segment in the tower area. By setting a quick matching and connection device on the upper chords, high-precision and fast docking of the steel stringing beams of large sections can be realized.
