Outlined in the introduction to this article in the high purpose and significance of dump truck design modifications, development status and application prospect and the main content, and overall design of this technique. Then analysis demonstrates a total quality is 9t of high level design of dump truck, chassis selection analysis of second class, Vice-frame designs, lifting bodies, dump bodies and back door opening-closing mechanism, made a detailed exposition. Also includes analysis of the principal organs of the programmes and selected, movement analysis, dynamic analysis and calculation of strength and stiffness checking to briefly explain the calculation method for design of hydraulic system and process, and selection of hydraulic products. Last modified high dump truck after the completion of the necessary powe
