To provide a measuring method and a measuring device which can measure a position in a horizontal direction of a hoisting attachment with good accuracy, and a hoisting attachment.SOLUTION: A hoisting attachment 1 comprises a pair of targets 4 which are arranged at an interval in a first direction x, which are installed in the hoisting attachment 1 in a state where an interval D in the first direction x of the targets 4 becomes larger from one end sides of the targets 4 toward the other end sides in a second direction y crossing at a right angle the first direction x. Laser light is emitted to the targets 4 from a laser distance meter 5 to obtain positional information on the targets 4, the interval D between the targets 4 in the first direction x is calculated from the obtained positional information to determine a position in the second direction y of the hoisting attachment 1 on the basis of the interval D and to determine a position in the first direction x of the hoisting attachment 1 from the positional information.SELECTED DRAWING: Figure 5

    【課題】吊具の水平方向における位置を精度良く測定できる測定方法および測定装置および吊具を提供する。【解決手段】吊具1が第一方向xに間隔をあけて配置される一対のターゲット4を備えていて、第一方向xを直角に横断する第二方向yにおけるターゲット4の一端側から他端側に向かってターゲット4どうしの第一方向xにおける間隔Dが大きくなる状態で吊具1に設置されていて、レーザ距離計5からターゲット4にレーザ光を照射してターゲット4の位置情報を取得して、取得された位置情報から第一方向xにおけるターゲット4どうしの間隔Dを算出してこの間隔Dに基づき第二方向yにおける吊具1の位置を決定するとともに、位置情報から第一方向xにおける吊具1の位置を決定する。【選択図】図5
