摘　　要：阐述了旅客登机桥的作用及对液压系统的要求。介绍了LTQ-2000Y型旅客登机桥的液压系统的设计实践,包括油源系统、升降回路、行走回路、转向回路、调平回路、回转回路和应急回路的设计。归纳了该液压系统的主要特点:控制、操作方式多样;油源高效、节能;行走、制动可靠;升降同步、可控;调平自动、及时。这些特点在设备使用中得到了良好的体现。The passenger boarding bridge＇s function and its requirement to the hydraulic system were expatiated. The design practices of the LTQ-2000Y passenger boarding bridge＇s hydraulic system were described, including the design of the oil source sys- tem, lifting loop, walking loop, steering loop, leveling loop, rotating loop and emergency loop. The main features of the hydraulic system were generalized： the control and operation modes were varied; oil source was efficient and energy-saving; walking and bra- king was reliable; up ＆ down lifting was synchronized and controllable; leveling was automatically and timely. These features are well reflected when using the device.
