The hydraulic lift is required to complete the work. The thesis briefly describes the design process of hydraulic lift. By analyzing the structural form and moving mechanism of the elevator get the design framework and explain the campaign process in detail, to optimize the bracket selection. Analysis power needed to lift to formulate overall plan and design of hydraulic system of hydraulic cylinder structure, and select from the standard form of hydraulic components and their connections. Results of final design for open-type hydraulic system of double single fork lift. The hydraulic lift system structure is simple which can effectively reduce the mechanical energy loss. At the same time, the mainly parts is some standard parts which conform easy maintenance replacement and low costly. This design enables simple, practical, low cost design goals. The hydraulic lift to move goods to 2500Kg to 1.5m high. It can be used for facade decoration, storage transportation, municipal gardens, and other occasions.
