To correctly determine a swing state of a suspension rope even when a detection device is not mounted on the suspension rope and a hanging-down length of the suspension rope is long.SOLUTION: A suspension rope swing determination method determines a swing state of a suspension rope 32 suspended from a tip part of a boom 21 of a crane. As steps executed by a data processing device, a step of acquiring data of a three-dimensional detection position Px1 of an object detected by an object detection sensor 45 fixed to the boom 21 and a step of deriving a swing direction and a swing angle of the suspension rope 32 from the data of the detection position Px1 are included.SELECTED DRAWING: Figure 1

    【課題】検出装置が吊りロープに装着されることなく、前記吊りロープの垂下長さが長い場合でも前記吊りロープの振れ状態を正しく判定すること。【解決手段】吊りロープ振れ判定方法は、クレーンのブーム21の先端部から垂下される吊りロープ32の振れ状態を判定する方法であり、データ処理装置により実行される工程として、前記ブーム21に固定された物体検出センサー45により検出される物体の3次元の検出位置Px1のデータを取得する工程と、前記検出位置Px1のデータから、前記吊りロープ32の振れ方向および振れ角度を導出する工程とを含む。【選択図】図1
