Disclosed is a hydraulic jack device capable of connecting a preferred number of hydraulic jack devices in parallel. According to the present invention, the hydraulic jack device can comprise: a plurality of hydraulic jacks where an operation body is moved forward and backward by internal hydraulic pressure of a cylinder; and a parallel connection unit enabling adjacent hydraulic jacks to be separably coupled to each other between adjacent hydraulic jacks among the hydraulic jacks.

    복수개의 유압 잭 장치를 원하는 만큼 병렬로 연결 가능한 유압 잭 장치가 개시된다. 본 발명에 의한 유압 잭 장치는 실린더 내부의 유압에 의해 작동체가 전후진하는 복수개의 유압 잭 및 상기 복수 개의 유압 잭 중 서로 이웃하는 유압 잭 사이에 서로 이웃하는 유압 잭을 상호 분리가능하게 결합시킬 수 있는 병렬연결부를 포함할 수 있다.
