To provide a device for preventing a collision with objects including a moving object such as a worker by enabling 3D-measurement of the handling object and an object to be performed in real time with a simple equipment configuration, so as to grasp the size of the handling object when lifted by the crane, and to decelerate/stop the crane according to the information.SOLUTION: A collision prevention device in a crane acquires cargo profile information of a handling object 09 handled by a crane 01 and information on an object 17 in real time using a 3D-range sensor 23 mounted on the crane 01; calculates speed for preventing collision between the handling object 09 and the object 17 by adding the cargo profile information of the handling object 09 and the information of the object 17, to speed at a time with no cargo so as to allow the crane to be operated on the basis of the calculated speed..SELECTED DRAWING: Figure 9

    【課題】簡易な設備構成で、取扱物及び対象物の3次元の計測をリアルタイムで行うことを可能とすることによって、取扱物の大きさをクレーンの吊上時に把握し、その情報に応じて減速、停止を行うことで、作業者などの移動している対象物を含む対象物との衝突を防止する装置を提供すること。【解決手段】クレーン01に搭載した3次元測域センサ23を用いてクレーン01が荷役する取扱物09の荷姿情報及び対象物17の情報をリアルタイムで取得し、取扱物09と対象物17の衝突を防止する速度を空荷時の速度に取扱物09の荷姿情報及び対象物17の情報を加えて算出し、該速度に基づいてクレーンの運転を行うようにする。【選択図】図9
