PROBLEM TO BE SOLVED: To provide a deflection angle detection device of a crane suspended load which can enhance durability without requiring a mechanical contact part with respect to a wire rope, enhance detection accuracy by eliminating an error caused by the deflection of the wire rope, and be hardly restricted on an attachment place.SOLUTION: A base point side sensor 12 for detecting positional information of X-axis, Y-axis, and Z-axis directions in a base point is attached to a tip of a gib 4 that becomes the base point from which a hoisting wire rope 11 is suspended. A suspension tool side sensor 13 for detecting positional information of X-axis, Y-axis, and Z-axis directions in a suspension tool 9 is attached to the suspension tool 9 at the lower end of the hoisting wire rope 11. An arithmetic unit 14 determines a deflection angle θ of the suspension tool 9 based on a difference between the positional information detected by the base point side sensor 12 and the positional information detected by the suspension tool side sensor 13.
【課題】ワイヤロープに対する機械的な接触部を不要として耐久性を高めると共に、ワイヤロープの撓みに伴う誤差をなくして検出精度を高めることができ、且つ取付箇所に関する制約を受けにくくし得るクレーン吊荷の振れ角検出装置を提供する。【解決手段】巻上ワイヤロープ11が吊り下げられる基点となるジブ4の先端に、該基点におけるX軸、Y軸、Z軸方向の位置情報を検出する基点側センサ12を取り付け、巻上ワイヤロープ11下端の吊具9に、該吊具9におけるX軸、Y軸、Z軸方向の位置情報を検出する吊具側センサ13を取り付け、基点側センサ12で検出した位置情報と前記吊具側センサ13で検出した位置情報との差分に基づき吊具9の振れ角θを演算装置14で求める。【選択図】図1
