500t Gantry Crane for Bridge Structure Hoisting
A key construction milestone has been achieved on the Maanshan Yangtze River Rail-cum-Road Bridge project undertaken by China Railway No.9 Bridge Engineering Co., Ltd. The first-round overall assembly acceptance of the project’s Z3 steel tower has been successfully passed. As the core equipment provider, Henan Mine Crane supplied the 500-ton gantry crane for the key construction and acceptance work, which marks a new breakthrough in China’s modern bridge construction technology and engineering development.
Henan Mine Crane serves as an important equipment supplier for this national super infrastructure project. To support the overall construction of the Maanshan Yangtze River Rail-cum-Road Bridge, the company has provided more than 10 sets of high-quality crane equipment, including 500-ton and 400-ton gantry cranes. All tailor-made crane products are put into the hoisting construction of core bridge structures, especially the main steel towers of the grand bridge. Featuring stable operation, high hoisting precision and strong load-bearing performance, these high-end cranes have fully ensured the safety, efficiency and construction quality of key hoisting processes, providing reliable and solid equipment support for the steady advancement of the project.
The Maanshan Yangtze River Rail-cum-Road Bridge is a landmark super project of the Chaohu-Maanshan Intercity Railway with world-class technical parameters and construction scale. The bridge adopts an advanced three-tower and two-main-span structural design. It has a single main span of 1,120 meters and a continuous double-span total length of 2,240 meters, making it one of the world’s largest-span three-tower cable-stayed bridges. Benefiting from its ultra-large span and complex structural design, the project sets extremely stringent standards for construction accuracy, equipment stability and engineering technology, which represents a high-standard test for the strength of supporting manufacturing and construction enterprises.
The successful delivery and operation of equipment for the Maanshan bridge project is another powerful proof of Henan Mine Crane’s strength in supporting national major infrastructure development. The company has long been committed to empowering high-end national equipment manufacturing and super engineering construction. It has previously provided professional crane equipment and technical support for a number of national key bridge projects, including Jianzhou Bridge, Changtai Yangtze River Bridge and Zhangjinggao Yangtze River Bridge. Backed by outstanding intelligent manufacturing capacity, leading core technologies, rich project experience and a complete full-life-cycle service system, Henan Mine Crane has always delivered high-quality solutions for major transportation infrastructure projects.
In the construction of the Maanshan Yangtze River Rail-cum-Road Bridge, Henan Mine Crane continuously optimized equipment performance parameters and on-site supporting service plans, effectively accelerating the overall construction progress of the super project. By empowering national key bridge engineering with intelligent manufacturing achievements, the company practices the corporate responsibility of building high-end national heavy equipment. It steadily contributes professional manufacturing strength to the high-quality development of the Yangtze River Delta integrated development strategy and the upgrading of China’s modern transportation infrastructure network.
