A high place work device for preventing a caught-in accident, 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; a mobile cart connected to the up-down lift unit to horizontally move the high place worktable; and a caught-in prevention unit which is provided on the high place worktable and prevents an accident of a worker by an upper structure such as a ceiling or a girder during the operation of the up-and-down lift unit. In the high place work device for preventing a caught-in accident according to the present invention, a temporary structure is provided as much as a minimum space for the worker and an external force detection unit detects a mechanical signal to minimize malfunction or failure, so that the safety of the worker can be sufficiently guaranteed. In addition, obstacles which are irregular and uneven, such as girders or steps, can be reliably detected, so that a safety accident such as the worker being caught in/between objects can be prevented.

    본 발명에 의한 끼임사고방지를 위한 고소작업장치는, 고소 작업을 위한 고소작업대와, 상기 고소작업대를 승하강시키는 업다운 승강부와, 상기 업다운 승강부와 연결되어 상기 고소작업대를 수평이동시키는 이동대차; 및 상기 고소작업대에 마련되어 상기 업다운 승강부의 동작 시 천장 또는 대들보 등의 상부 구조물에 의해 작업자의 끼임사고 발생을 저지하는 끼임방지유닛을 포함할 수 있다. 본 발명에 의한 끼임사고방지를 위한 고소작업장치는, 작업자의 최소 공간만큼 임시 구조물이 마련되고 외력감지부를 통해 기계적 신호를 감지하여 오작동이나 고장이 최소화되어 작업자의 안전이 충분히 보장될 수 있으며 대들보나 단턱같이 불규칙적이고 불균일하게 있을 수 있는 장애물도 신뢰성있게 감지하여 작업자가 끼이는 등의 안전사고가 미연에 방지될 수 있다.
