The present invention relates to a crane safety device, which includes a sensing means installed at an end portion of a crane in a traveling direction to detect an obstacle located on a traveling path of the crane and to obtain detection data, in order to maximize reliability of use by stably detecting the obstacle located on the crane travel path regardless of a vertical position of the obstacle. The sensing means includes: a fixing block which is installed to protrude while having a length from the end portion of the crane in the traveling direction to a proceeding direction; a support member rotationally and axially coupled to the traveling-side tip of the fixing block in a selected direction to rotate by impact pressure when colliding with an obstacle; and a sensor configured to obtain the detection data by detecting a rotational state of the support member.

    본 발명은, 크레인의 주행경로상에 위치된 장해물의 상하위치에 관계없이 안정적으로 감지하도록 되어 사용의 신뢰성을 극대화하도록; 크레인의 주행방향측 단부에 시설되어 상기 크레인의 주행경로상에 위치된 장해물을 감지하여 감지데이터를 얻도록 된 감지수단;을 포함하여 이루어지는 크레인 안전장치에 있어서; 상기 감지수단은, 상기 크레인의 주행방향측 단부에서 진행측 방향으로 길이를 가지면서 돌출되게 시설되는 고정블럭과; 상기 고정블럭의 주행측 선단에 선택된 방향으로 회동가능하게 축결합되어 장해물과의 충돌시 충돌압에 의해 회전운동하도록 된 지지부재와; 상기 지지부재의 회동상태를 감지하여 감지데이터를 얻도록 된 감지센서;를 포함하여 이루어지는 크레인 안전장치를 제공한다.
