The telescopic boom is the main bearing force component of the crane. The rationality of the design will directly affect the performance of the machine and safety. The telescopic boom is a typical thin-walled plate and shell structure. Its main form of damage is the occurrence of buckling, resulting in decreased carrying capacity, or even a security incident. In order to meet the lifting weight and height, to ensure the stability of the telescopic boom has become a major problem of the designer. There are many factors that affect the critical load of the telescopic boom, including support method, inertia moment, length and material. When the support mode, material and length are determined, the maximum factor affecting the buckling critical load is the inertia moment. In this paper, the influence of the section size on the buckling critical load of the telescopic boom is analyzed by using the inertia moment of section method ande finite element method. And the sensitivity analysis is carried out on this basis. The results of the analysis can provide designers with design reference basis. Then a reasonable cross-sectional size can be used to improve the buckling resistance capacity of the telescopic boom.
