It is to reduce labor intensity, speed up the construction speed, improve project quality plays an important role. With the development of Chinas manufacturing industry, the requirements for the design and manufacture loaders are also increasing, while the traditional design method has many deficiencies, such as long design cycles, poor design quality, high design costs, does not reflect the whole structure stress distribution, it is difficult to meet customer needs. This paper first introduces the research background, trends and design issues loaders, analyzes the overall structure of the loader, loader working device for a brief introduction; Then use the three-dimensional design software SolidWorks completed the loader working device 3D design, build the whole structure and motion simulation model, to understand the actual work; Finally, the use of static analysis plug-ins SolidWorks Simulation SolidWorks comes to bear on the loader loads the main component analysis of the deformation and stress conditions in order to be be
