The 700 t gantry crane built by Henan Mine Crane for the steel tower of the Zhangjinggao Yangtze River Bridge has passed its type test, another contribution to China's bridge construction after the Jianzhou, Changtai Yangtze River and Ma'anshan Yangtze River road-rail bridges.
As a key equipment supplier to this mega project, the company's 700 t and other premium cranes are all used to erect the main steel towers and other bridge structures, providing strong support for the project.
The bridge's main tower is 350 m high — equivalent to a 125-storey building — and is the water-side tower among the four main towers of the bridge's two navigation spans. Once complete it will be one of the world's largest suspension bridge pylons.
Using modern computer technology, advanced domestic components, new materials and new processes, the cranes are lightweight, standardised, energy-saving, environmentally friendly and technologically advanced heavy-tonnage, long-span, high-lift engineering gantry cranes.

In recent years, with solid product quality, stable and reliable performance and superior technology, Henan Mine Crane has become a preferred brand for major national projects in bridges, defence and aerospace. The company will always hold to its quality philosophy of "only the best will do", develop more high-quality products and contribute more to high-quality development of China's lifting industry.
