in order to meet the complex requirements of existing construction conditions in the line, especially to solve the problems of 29.98 ‰ large slope line erection and thin rod arch temporary and out of arch erection, XCMG Railway Equipment Co., Ltd. has developed a complete set of 550t unwheeling equipment. Tj550 bridge erecting machine adopts double span, double support structure and walking through hole method. It is mainly used for the transportation and erection construction of single track prefabrication or labor-intensive traditional manufacturing concrete simply supported box girder in the construction of high-speed railway, passenger dedicated line, intercity railway and high-speed railway connecting line. It makes up for the slope of the support surface by adjusting the height difference of each leg, and sets a transverse lifting and support mechanism, To better adapt to the complexity of box girder construction and the stability of construction operation, the progressiveness of its technology ranks in the forefront in China, and the application of construction method fills the domestic blank of single track box girder erection
