According to parameters ,this paper elected for the boom of the total length of 37 meters basis on the reference concrete pump boom system in the study design, , and the number of the selected boom section, and sections of arm length, section form, articulated forms, institutional forms, determined by calculating each arm hinge Department link, angle bar length, and cylinder stroke at the same time, and the design of various components of the size and paramenters,and check them. Meanwhile, the paper design parameters in accordance with the use of solidworks modeling, rendering a three part plan and three assembly drawings, and further more intuitive structure of the truck boom.
