Recently, the 700t gantry crane manufactured by our company for the steel tower construction project of Zhangjinggao Yangtze River Bridge successfully passed the type test. This marks another instance of  Henan Mine Crane contributing to my country's bridge construction, following the Jianzhou Bridge, Changtai Yangtze River Bridge, and Ma'anshan Yangtze River Railway-Highway Bridge.

As a key equipment supplier for this mega-project, Henan Mine Crane manufactured several sets of high-quality cranes, including a 700-ton crane, which were all used in the hoisting of the main steel tower and other bridge structures, providing strong support for the construction of the Zhangjinggao Yangtze River Bridge.

It is understood that the main tower of the bridge is 350 meters high, equivalent to the height of a 125-story building. It is the main water tower among the four main towers of the two navigation channel bridges of the Zhangjinggao Yangtze River Bridge, and will become the world's largest suspension bridge tower upon completion.

The cranes in this project are developed and manufactured using modern computer technology, advanced domestic configurations, new materials, and new processes. They are lightweight, versatile, energy-saving, environmentally friendly, and high-tech engineering gantry cranes with large tonnage, large span, and large lifting height.

Technological advantages

01 The entire crane adopts a PLC and variable frequency drive (VFD) communication control system, ensuring smoother operation, enhanced safety, and greater reliability.

02 Synchronized Control of Multiple Lifting Points Automatically Maintains Load Balance, Delivering Energy-Efficient Operation and Improved Lifting Efficiency.

03 The entire crane adopts a fiber-optic communication system, ensuring interference-free signal transmission and a high level of system integration.

04 Equipped with an Automatic Positioning System for Greater Precision and Efficiency, Meeting the Stringent Requirements of Bridge Construction Projects.

In recent years, Henan Mine Crane has become a preferred brand for major national projects such as bridges and aerospace, thanks to its superior product quality, stable and reliable operation, and excellent technological advantages. Henan Mining will always adhere to the quality philosophy of "making the best products possible," developing more high-quality products and contributing more to the high-quality development of China's crane industry.
