In industrial production, all kinds of elevator is used for transport and positioning tool, due to the hydraulic lift high performance, the use of the hydraulic lift is quite widespread, it not only convenient operation, and can greatly improve the work efficiency. Lift is also used in metallurgy industry; the important equipment is widely used in metallurgy, welding, painting, handling, assembling and the workplace. The design of hydraulic drive system, lifts belong to design process according to the analysis of the operating mode requirement system the working conditions of the system, and the system to achieve work requirement, design the system diagram, and according to the principle diagram motor and hydraulic components selection, pipe line and other details of the row. According to the working conditions and the given work pressure, reasonable fitting hydraulic cylinder trajectory, the thrust calculation of hydraulic cylinder, select the appropriate. According to flow requirements choice of pump and matching motor, then overland flow of pipeline according to choose hydraulic components. Most of the components are designed by related parameters calculati
