Synchronous Hydraulic Lifting Jack System For Raising Bridge  

PLC multi-point synchronous jacking hydraulic system is divided into 5 parts: hydraulic pump station, PLC computer control system, hydraulic system, displacement pressure detection and man-machine interface operating system. The system integrates hydraulic jacking system, computer PLC signal processing, displacement monitoring with bridge structure analysis and construction technology, and develops a complete set of technologies on the integrated system. Its core is to design the computer PLC signal processing and hydraulic system according to the bridge characteristics based on the bridge structure analysis and construction technology summary, input the displacement signal of the external monitoring facilities, output the hydraulic system oil quantity control signal, and use the terminal multi-group jin.Synchronized Lifting Jacks…
