Abstract Research and analysis on main beam on the longtime used 25 t×27.5 m bridge type crane is executed by adopting FEA method and Finite Element code MSC.MARC. According to measured dimensions, deformations of bridge frame and stress distribution on it are analyzed from the aspects of experimental load case and design load case respectively. Furthermore, its structural mechanics features are presented and compared with the experimental results, which provides theoretical base for confirming its life span.
