To quickly determine a winding failure of a rope around a drum of a winch device at a slightly deteriorated stage.SOLUTION: A winch monitoring method monitors a state of a winch device 161 winding a rope 31 around a drum 161. The winch monitoring method acquires an image photographed by a camera 45 arranged to face the drum 161 (S101). Further, the winch monitoring method determines the presence/absence of the winding failure of the rope 31 and the failure degree showing the degree of failure about the winding failure based on the photographed image and outputs a determination result (S105, S106, S111, S112).SELECTED DRAWING: Figure 5

    【課題】ウインチ装置のドラムにおけるロープの巻き取り不良を軽度の段階で速やかに判定すること。【解決手段】ウインチ監視方法は、ドラム161にロープ31を巻き取るウインチ装置161の状態を監視する方法である。前記ウインチ監視方法は、前記ドラム161に向けて配置されたカメラ45による撮影画像を取得することを含む(S101)。さらに、前記ウインチ監視方法は、前記撮影画像に基づいて前記ロープ31の巻き取り不良の有無および前記巻き取り不良の程度を表す不良度を判定し、判定結果を出力することをふくむ(S105,S106,S111,S112)。【選択図】図5
