The present invention relates to a device for safely and simultaneously lifting a bridge, more specifically, which comprises: a main ram lifting a workpiece with main ram supply oil supplied from the outside; and a safety ram arranged at one side of the main ram, and supplied with main ram discharge oil discharged from the main ram to communicate with the main ram. The safety ram has a safety supporter lifted at a height corresponding to a lifting height of the workpiece lifted by the main ram. Therefore, working stability can be improved.
본 발명은 교량의 안전 동시인상장치에 관한 것으로서, 특히, 외부로부터 공급되는 주램 공급 오일을 이용하여 작업 대상물을 승하강시키는 주 램과, 상기 주 램의 일측에 배치되고, 상기 주 램으로부터 토출되는 주램 토출 오일을 공급받아 상기 주 램과 연동하는 안전 램을 포함하고, 상기 안전 램은, 상기 주 램에 의하여 승강되는 상기 작업 대상물의 승강 높이와 대응되는 높이로 승강되는 안전 서포터를 포함함으로써, 작업 안정성을 향상시킬 수 있는 이점을 제공한다.
