It has a decisive influence on the performance of the loader and the competitiveness of the loader in the market. The performance of the loader and the operational efficiency of the play, can not be separated from the hydraulic system design, and to a large extent depends on the hydraulic system efficiency.</p><p>The working device of the loader and the steering mechanism are taken hydraulic drive, this paper through the work device and steering mechanism requirements and load analysis of the hydraulic system design. Mainly include the implementation of components, control components of the selection of components, design.</p><p>The design of this paper can make the reader to further deepen the understanding of the hydraulic system design, at the same time from which you can experience some of the design concept for the future to engage in such work to get some help.</p><p><br/></p><p>Key words: loader
