Analysis of the Necessity of PLC Hydraulic Control System in Bridge Lifting Application

The overall lifting process of the bridge is a dynamic process that contains many uncontrollable factors.During the overall lifting process, there may be deviations between each link of the continuous box girder and the left and right sides of each pier, so the size of the deviation needs to be In the process of lifting, timely detection and corrective processing is carried out. Based on this, timely detection of deviation problems and corrective control after deviations have become the research focus of the current overall lifting process of bridges.
