• Abstract: 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. 根据济南凤凰路黄河大桥的顶推工程，设计一种新型提梁装置。重点介绍了提梁装置的结构组成、施工工艺流程与应用效果，并对整个结构进行有限元分析。 综合分析表明，该新型提梁装置能够适应腹板间距变化的钢箱梁，且能满足双向顶推施工需求，结构转换快捷，施工效果好，具有较强的可调性与适用性。
