The present invention relates to a safety lifting system for a greenhouse comprising: a lifting preparation step of dismantling or cutting an existing facility a lifting waiting step of combining an lifting apparatus (120) to each pillar (110), and cutting and separating lower portions of the pillars (110) when the lifting preparation step is completed a safety preparation step of setting multiple support points, combining a safety against overturning apparatus (130) to the support points, and increasing a bearing power of a structure of a greenhouse (100) when the lifting waiting step is completed a lifting step of simultaneously operating the lifting apparatus (120) installed in the pillars (110) and gradually lifting the pillars (110) to the preferred height when the safety preparation step is completed a pillar connecting step of inserting connecting pipes (112) in gaps of cutting portions (111) of each lifted pillar (110), and compressing and solidly combining when the lifting step is completed a windbreak-wall installation step of combining a truss (140) on an external side of the structure when the pillar connecting step is completed and a completion step of installing and connecting various facilities when the windbreak-wall step is completed. When lifting the pillars of the greenhouse, the present invention enables to exactly support and safely and effectively lift as well as continuously maintaining a safe supporting state of the greenhouse pillars in order to safely and smoothly carry out a greenhouse pillar lifting work. The present invention enables to prevent the overturning of an existing structure while carrying out the lifting work as well as enabling to effectively carry out a process by minimizing a transformation.COPYRIGHT KIPO 2015본 발명은 온실 안전 인상시스템에 관한 것으로, 기존시설물을 해체하거나 절단하는 승강준비단계와, 상기 승강준비단계가 완료되면 각각의 기둥(110)에 인상장치(120)를 결합시킴과 동시에 기둥(110)의 하부를 절단하여 분리하는 승강대기단계와, 상기 승강대기단계가 완료되면 지지포인트를 다수개 설정하고 지지포인트에 전도방지장치(130)를 결합하여 온실(100) 구조물의 지지력을 증대시키는 안
