The synchronous lifting system consists of an electric motor,
high-pressure hydraulic pump, oil tank and operation control
system, jack and oil pipe, splitter, etc.
The flow rate of a pumping station is outputted through a splitter
and provided to each executing oil cylinder. The displacement
control system controls the loading and lifting speed of each oil
cylinder based on the feedback signal from each different measuring
point, achieving synchronous lifting action of the entire concrete
continuous beam.
As modern transportation becomes increasingly busy, the frequency
of reinforcement work for highway bridges and overpasses will
increase. By adding additional piers and evenly distributing the
load of the bridge beams to the old piers, the traffic flow can be
increased.
The use of ultra-thin hydraulic jacks or self-locking hydraulic
jacks to lift the bridge, replace the cushion layer, and finally
place it back in the new pier position is the current stable
maintenance of the bridge.
