This is a 3D model of a manual hydraulic forklift modeled using SolidWorks. The model includes motion simulation animations produced by SolidWorks, which mainly demonstrate the motion process of components such as chains, sprockets, forks, hydraulic cylinders, etc., and intuitively demonstrate the principle of lifting forks. The use of assembly relationships such as chain arrays and linear coupling in the SolidWorks software interface is a challenge in creating chain animations. Through this model, it can help everyone have a new understanding of SolidWorks chain assembly.In addition, for the convenience of other friends learning, I have processed the model and included two SolidWorks folders, one in English and the other in Chinese. In addition, for the learning of friends in other industries, I have converted the model into various formats here, including stp, x_t format, as well as c4d, obj, fbx, and Maya's mb format. In addition, materials have been added to various components of the model in Maya's mb format file.Thank you all for your support.
