To provide an over-winding detection device capable of easily performing relocation work of an over-winding detection weight when replacing a wire rope for single-rope winding.SOLUTION: An over-winding detection device 1 used for a wire rope 4 for single-rope winding that is wound around one sheave 3 and then suspended such that a cargo hook 5 is mounted on a tip end. The over-winding detection device includes an over-winding detection switch 11 suspended in the vicinity of the sheave 3, and an over-winding detection weight 15 for detecting the over-winding of the cargo hook 5. In a state where the over-winding detection weight 15 is abutted on an upper part of the cargo hook 5, the over-winding detection weight 15 is automatically connected to or released from the over-winding detection switch 11.SELECTED DRAWING: Figure 1

    【課題】 1本掛けワイヤロープを掛け替えする際に、容易に巻過検出ウエイトの移設作業ができる巻過検出装置を提供する。【解決手段】 1枚のシーブ3に掛け回されたのち吊下され先端に吊荷用フック5が取付けられる1本掛けワイヤロープ4に用いられる巻過検出装置1であって、前記シーブ3近傍に吊下される巻過検出スイッチ11と、前記吊荷用フック5の巻過を検出する巻過検出ウエイト15と、を備え、前記吊荷用フック5の上部に前記巻過検出ウエイト15が当接した状態において、前記巻過検出スイッチ11に対し前記巻過検出ウエイト15が自動で連結又は解除される。【選択図】 図1
