To provide a safety device in a crane that can directly detect an inclination of a handling object handled by the crane by enabling three-dimensional measurement of the handling object in real time with a simple equipment configuration.SOLUTION: A safety device in a crane acquires cargo profile information of a handling object 09 handled by a crane 01 in real time using a 3D-range sensor 23 mounted on the crane 01, calculates respective differences between heights at a plurality of positions of the handling object 09 at the time of landing and heights at the plurality of positions of the handling object 09 at a time of lifting, and detects an inclination of the handling object 09 from the calculated differences.SELECTED DRAWING: Figure 5

    【課題】簡易な設備構成で、取扱物の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、クレーンが荷役する取扱物の傾斜を直接検出することができるクレーンにおける安全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の荷姿情報をリアルタイムで取得し、着床時の取扱物09の複数箇所の高さと、吊上時の取扱物09の当該複数箇所の高さとの差を算出し、算出した差から取扱物09の傾斜を検出する。【選択図】図5
