TRSM Bridge jack up synchronous jack
Function
The synchronous lifting of bridges is divided into four steps: weighing, lifting, maintaining position, and lowering with load.
- Weighing
Before the bridge is officially lifted, it should be weighed to determine the actual pressure at each lifting point. Firstly, based on the estimated pressure at each jacking point, slowly increase the outlet pressure of each pressure reducing valve; When the output of the jack exceeds the beam load it bears, a slight displacement will be generated at that point. At this time, the displacement sensor will transmit the measured data back to the programming controller, and then the controller will issue a stop command to the jack associated with the displacement sensor; When the outlet pressure of all pressure reducing valves stabilizes, the beam body detaches from the support, and its mass is fully borne by the hydraulic jack cluster, and the weighing process is declared finished. At this point, the pressure of each jack is the equilibrium pressure.

- Synchronous jacking of bridges
After the weighing is completed, the programming controller issues a command again to assign the same pressure increment to each jack pressure reducing valve, so that all jack cylinder bodies can rise synchronously. The lifting speed can be adjusted by adjusting the pressure increment of the pressure reducing valve.
- Maintain position
When the lifting reaches the limit of the jack stroke and the set amplitude, the controller sends a stop command to all jacks. The outlet pressure of the pressure reducing valve remains constant, and the one-way valve is used to keep the jack cylinder in the current position.
- Load descent
When lowering under load, the programming controller issues a command to assign the same pressure reduction to each jack pressure reducing valve, causing all jack cylinder bodies to descend synchronously. The descent speed can be adjusted by adjusting the pressure change of the pressure reducing valve.
