Structure of telescopic boom is becoming increasingly complicated, since truck crane with excellent performance, larger-ton as well as intelligence has dominated the tendency of development, enterprises home and abroad attach importance to the investigation of telescopic boom and some achievements have been obtained. So far, structure of telescopic boom with single cylinder and pinning system equipped with high intelligence and reliable performance represents the newest technology.Targeted with telescopic boom with single cylinder and pinning system, The paper builds the model of the whole telescopic boom and designs the newfashioned pinning structure by using 3-D sofeware Solidworks, meanwhile, the two approaches is used to calculate stability of cylinder for changing working scope, which lays solid foundation for the concerned stability calculation of upper system.Secondly, The paper investigates the statics of telescopic boom and calculates the static and dynamic stiffness concerned as well as having analysis to dynamics of boom system, dynamic equations are built by using Lagrange equation, which provides strong proof for the optimization design of telescopic boom, meanwhile, the paper studies the advantages and disadvantage of telescopic boom with different cross-section respectively, then, press analysis of four booms with hexagon cross-section is implemented by using drag-style design software COSMOS/works integrated into Solidworks, more specifically, at the background of crane with lifting competence 25 ton(rating load), contour plot of press and displacement for each boom in all-extended condition are also studied, which contributes to strengthening design of slide-pad attached to moving boom and also confirms location of regional stress concentration for each boom. Finally, the cross-section size for the first telescopic boom is optimized by using optimization toolbox provided by MATLAB software which brings about the reducing gross weight of the whole system, furthermore, ending part in the paper briefs the stability of boom system and quantitative calculation is implemented based on the boom with hexagon cross-section.
