Whether it is a major overhaul of the entire vehicle or a minor repair and maintenance, it is indispensable. The nature and quality of its products directly affect the personal safety of maintenance personnel. In maintenance and repair enterprises of various sizes, whether it is a comprehensive repair shop that repairs a variety of models or a street shop with a single business scope, almost all are equipped with lifts. The working principle of a lift is usually to drive the cylinder piston rod through the hydraulic cylinder set on it, and the cylinder piston rod drives the connecting rod system set between the lifting workbench and the base, and the lifting workbench is extended and retracted through the connecting rod system to achieve parallel lifting.
