The present invention relates to a simultaneous lift system of a bridge capable of controlling a lift speed by a bridge load using a multi-piston pump and motor control and, more specifically, relates to a simultaneous lift system of a bridge capable of controlling a lift speed by a bridge load using a multi-piston pump and motor control, wherein a discharge port is individually connected for each of twelve mini pumps provided in a multi-piston pump to control a flow rate required in accordance with pressure applied to bridge lift. Therefore, a plurality of hydraulic jacks required for bridge lift can lift a bridge at the same time with the same pressure.

    본 발명은 멀티피스톤펌프와 모터 제어를 이용한 교량하중에 따른 인상속도 제어가 가능한 교량 동시 인상 시스템에 관한 것으로서, 멀티피스톤펌프에 구비된 12개의 미니펌프 별로 토출구를 개별 연결하여, 교량 인상에 걸리는 압력에 따라 필요한 유량을 조절함으로써, 교량 인상에 요구되는 복수 개의 유압잭이 동일한 압력으로 동시에 교량을 인상할 수 있도록 하는, 멀티피스톤펌프와 모터 제어를 이용한 교량하중에 따른 인상속도 제어가 가능한 교량 동시 인상 시스템에 관한 것이다.
