To provide a crane hook position warning device that can easily and reliably confirm that the positional relationship between a hook and a hoist is perpendicular.SOLUTION: A crane hook position warning device according to an embodiment comprises a light emitter including a light source, and a light receiver including a light receiving element disposed opposite to the light source and outputting a signal that becomes active upon receiving light emitted from the light source. The light emitter includes a first case that houses the light source so as to be able to emit light, a plumb bob provided to extend in a direction opposite to the direction in which the light is emitted, and a second case movably supporting the first case so that the direction of the light emitted from the light source is parallel to the extending direction of the plumb bob.SELECTED DRAWING: Figure 2

    【課題】フックとホイストとの位置関係が垂直であることを容易かつ確実に確認できるクレーンフック位置警報装置を提供する。【解決手段】実施形態のクレーンフック位置警報装置は、光源を含む発光器と、前記光源に対向して配置されて前記光源から出射された光を受光することによってアクティブとなる信号を出力する受光素子を含む受光器と、を備える。前記発光器は、光を出射可能に前記光源を収納する第1ケースと、前記光の出射方向の反対方向に延伸するように設けられた下げ振り錘と、前記光源からの光の出射方向が前記下げ振り錘の延伸方向に平行となるように前記第1ケースを可動自在に支持する第2ケースと、を含む。【選択図】図2
