PROBLEM TO BE SOLVED: To provide a position measuring target, to measure a position of a hanging tool (spreader), capable of improving accuracy of measuring the position of the spreader and maintaining measuring accuracy particularly when the spreader is away from a laser range finder.SOLUTION: A target 2 comprises an inclined section 22 which has a predetermined shape to enable positional coordinates of a measuring point P4, which is arranged on the inclined section 22 and reflects a laser beam, to be used for obtaining a distance from the point to a boundary portion 23 at an upper edge or a lower edge of the inclined section 22.SELECTED DRAWING: Figure 2

    【課題】吊具(スプレッダ)の位置を測定する位置測定用ターゲットにおいて、スプレッダの位置を測定する測定精度を向上し、特にレーザ距離計からスプレッダが離れている場合であっても、測定精度を維持することができる位置測定用のターゲットを提供する。【解決手段】ターゲット2が傾斜部22を備えていて、この傾斜部22がレーザ光を反射した傾斜部22の一つの測定ポイントP4の位置座標から傾斜部22の上端又は下端の境界部分23までの長さを導き出せる予め定めた形状を有している。【選択図】図2
