The content of the design is to designe a hydraulic system for aircraft maintenance lifting platform, and to make all the various ponents of it can plete the actions in accordance with the design requirements smoothly under a stable pressure. Hydraulic system of aircraft maintenance lifting platform is a loop of sequential movements. The main task of this manual is, according to the given technical parameters, to design a system to meet the job requirements, so that the support of the platform can be controled by four outrigger cylinders, going up and down by two lifting cylinders, and the horizontal shifting by a mobile cylinder. In order to plete the requirements of the working conditions better, and improve system reliability, a backup pump and hand pump were set up. The design mainly includes the calculation and selection of tanks, pumps and motors, the development of system solutions, selection of the main hydraulic ponents and other attachments, and the issues that should be paid attention to of this design and installation, etc. Through the adjustment and check to the program repeatedly, the main parameters of the system were determined, and so was the system ultimately, so that the design meets the design requirements basically. In order to prevent the occurrence of an accident, the system use a selflocking loop, so that in the case of an accident occurred in the system, it could be controlled. The purpose of this design is to make the hydraulic system designed can meet the demands at work, slso the requirements in the process, allowing the system to have characteristics of a smooth and reliable work,
