To provide a suspension tool swing angle and suspension tool height detection device for a crane capable of facilitating maintenance of a camera without hindering the visual field of the camera while preventing the interference of a wire rope of the crane with the camera.SOLUTION: A camera CM for performing successive photographing toward a vertical lower side is installed on a side lower surface of a suspension position of a wire rope WR on a crane. A plurality of markers MK are arranged with regularity on a top surface of a suspension tool HK suspended by the wire rope WR. The swing angle and height of the suspension tool HK are detected by measuring a distance L1 between the plurality of markers reflected on a video, which is projected by the camera CM.SELECTED DRAWING: Figure 1

    【課題】クレーンのワイヤーロープが、カメラと干渉したり、カメラの視界を妨げたりすることがなく、また、カメラのメンテナンスを容易に行うことができるようにしたクレーンの吊具振れ角度及び吊具高さの検出装置を提供すること。【解決手段】クレーン上のワイヤーロープWRの吊り下げ位置の側方下面に鉛直下方に向けて連続的に撮影するカメラCMを設置し、ワイヤーロープWRで吊り下げられた吊具HKの上面に複数個のマーカーMKを規則性を持たせて配置し、カメラCMに投影された映像に映し出された複数個のマーカー間距離L1を計測することで吊具HKの振れ角度と高さを検出する。【選択図】図1
