700t｜Henan Mine Assisted the Construction of Zhang Jinggao Yangtze River Bridge

Recently, the 700t gantry crane manufactured by our company for the steel tower construction project of the Zhangjinggao Yangtze River Bridge successfully passed the type test and became the second bridge construction in Henan Province after the Jianzhou Bridge, Changtai Yangtze River Bridge, and Ma'anshan Yangtze River Highway and Railway Bridge. .

As an important equipment supplier of this super project, many 700t and other high-quality cranes (sets) manufactured by Henan Mine are all used in the hoisting of bridge structures such as the main steel tower of the project, providing strong support for the construction of Zhangjinggao Yangtze River Bridge.

It is reported that the main tower of the bridge is 350 meters high, which is equivalent to the height of a 125-story building. It is the main tower on the water among the four main towers of the two waterway bridges of the Zhangjinggao Yangtze River Bridge. After completion, it will become the largest suspension bridge tower in the world.

The crane of this project adopts modern computer technology, adopts domestic advanced configuration, new materials, and new technology to develop and produce. machine.
