A high place work device capable of preventing overturn at a pothole, according to the present invention, comprises: a high place worktable for a high place work, an up-down lift unit for raising and lowering the high place worktable, and a mobile cart connected to the up-down lift unit to horizontally move the high place worktable; and an emergency stop unit which is provided on the mobile cart and urgently stops the operation of the up-down lifting unit or the mobile cart when the mobile cart is inclined due to a pothole on a floor surface or irregular upper and lower steps. In the high place work device capable of preventing overturn at a pothole according to the present invention, a ground detection unit provided on the mobile cart detects the pothole on the floor surface to prevent the operation of the lifting unit. In a case in which a mobile part moves with the high place worktable unfolded, the mobile cart is urgently stopped when the pothole is found, so that the overturning of the high place worktable is prevented in advance, thereby minimizing a safety accident of a worker.
본 발명에 의한 포트홀에 대한 전복방지가 가능한 고소작업장치는, 고소 작업을 위한 고소작업대와, 상기 고소작업대를 승하강시키는 업다운승강부와, 상기 업다운승강부와 연결되어 상기 고소작업대를 수평이동시키는 이동대차; 및 상기 이동대차에 마련되어 바닥면의 포트홀 또는 불규칙적인 상하 단차로 인해 상기 이동대차가 기울어질 때 상기 업다운승강부 또는 이동대차의 동작을 긴급 정지시키는 긴급정지유닛을 포함할 수 있다. 본 발명에 의한 포트홀에 대한 전복방지가 가능한 고소작업장치는, 이동대차에 마련되는 그라운드감지부가 바닥면의 포트홀을 감지하여 고소작업대의 승강부의 작동이 되지 않도록 하고 고소작업대가 펼쳐진 채로 이동부가 이동 시에는 포트홀 발견 시 이동대차를 긴급정지시켜 고소작업대의 전복을 미연에 방지하여 작업자의 안전사고가 최소화될 수 있다.
