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
