They are applicable to mid-air operation and transporting in factories, warehouses and railway stations and s oon. This paper introduces the work characteristics and the hydraulic system of the lift tables of with twin scissors2truss support. Integrated hydraulic system (IHS) off ers many advantages including reduced connectors, size plexity, and enhance d flexibility for installation and maintenance. It provides a cleaner, leak-free, less vib rant and more reliable solution to difficult machine control systemproblems. The next, this paper introduces application of the synchronous valve in hydraulic synchronous system, analyzes its work principle.
