According to the incremental launching construction of Jinan Fenghuang Yellow River Bridge, a new steel beam lifting device is designed. It focuses on the structural composition, construction process and application effects of the steel beam lifting device, and carries out a finite element analysis of the entire structure to verify its reliability. Comprehensive analysis shows that the new steel beam lifting device, which has the advantages of quick structure conversion, good construction effect, strong adjustability and applicability, adapts to Steel Box Girder with variable width and meets the requirements for incremental launching construction.
