Summary:The present invention relates to a lift-up apparatus, using a multi-stage hydraulic cylinder so as to stably lift heavy-weight equipment up to high floor even in a limited space. According to an adequate embodiment of the present invention, the lift-up apparatus comprises: a pair of mast assemblies disposed on a lift-up floor surface to face each other, wherein a lifted heavy loads to be lifted is formed between the mast assemblies, so as to be lifted up and down in multiple stages; a support beam of which both ends are connected to an operating end of the mast assemblies so as to apply a lifting force to the lifted heavy loads to lift the same; and hydraulic pack supplying oil pressure to a first-stage hydraulic cylinder and a second-stage hydraulic cylinder for operating multi-stage operation of each of the mast assemblies. 본 발명은 다단의 유압실린더를 적용하여 협소한 공간에서도 고중량물의 장비를 높은 층고까지 안전성 있게 인상할 수 있도록 한 리프트 업 장치를 제공한다. 본 발명의 적절한 실시 형태에 따르면, 인상시키고자 하는 인상 중량물을 사이에 두고 서로 대향하게 인상 바닥면에 배치되어 다단으로 승강동작하는 한 쌍의 마스트 조립체와; 상기 한 쌍의 마스트 조립체측 가동단에 양단이 각기 연결되어 인상 중량물에 인상력을 가하여 인상시키는 서포트 빔과; 상기 한 쌍의 마스트 조립체의 각기 다단 동작을 작동시키는 1단 유압실린더 및 2단 유압실린더에 유압을 공급하는 유압팩을 포함하여 구성된 것을 특징으로 한다.
