The present invention relates to a collision prevention device of a multi-ceiling crane. According to the present invention, an upper crane includes: a heavy matter detection unit to detect whether a heavy matter is placed at the same height as that of a lower crane; and an approach detection unit to detect whether the lower crane approaches. A control unit forcibly stops the upper crane moving towards the lower crane when the heavy matter is detected by the heavy matter detection unit and, at the same time, approach of the lower crane is detected by the approach detection unit. Accordingly, an accident caused by a fall of the heavy matter is able to be prevented.

    본 발명은 상측크레인에는 하측크레인과 동일한 높이에 중량물이 존재하는지 여부를 감지하는 중량물 감지부와, 하측크레인에의 근접 여부를 감지하는 근접 감지부가 각각 구비되고, 제어부는 상기 중량물 감지부에 의해 중량물이 존재함을 감지함과 동시에 상기 근접 감지부에 의해 하측크레인에의 근접을 감지할 경우에만 상측크레인이 하측크레인을 향해 이동됨이 강제 정지되게 제어하도록 구성됨을 특징으로 하는 다중 천장 크레인의 충돌 방지장치이 제공되며, 이를 통해 중량물의 낙하로 인한 안전사고를 미연에 방지할 수 있도록 한 것이다.
