Abstract： In order to evaluate structural integration of a M02-10t gantry crane which has been operating for about 15 years，a three-dimensional finite element model of the gantry crane was built by finite element analysis software ANSYS. The deformation and stress distribution of the gantry crane were analyzed，and the analysis result was compared with the field test data of the gantry crane. From the simulation and experimental results，it can be seen that the results of finite element simulations agree well with the field test data；also， the stiffness and strength of the crane still meet the safety requirements of crane operation.
Key words： gantry crane；finite element analysis；strain test；structural integration
