PROBLEM TO BE SOLVED: To provide a rope slack detection device capable of detecting slack of a rope delivered from a winch device without acquiring various physical amounts beforehand.SOLUTION: A rope slack detection device 2 includes a first detection part 21, a second detection part 22 and a slack detection part 23. The first detection part 21 detects movement of a rope in a delivery direction of the rope, on a path of the rope delivered from a winch device. The second detection part 22 detects an operation of the winch device. The slack detection part 23 detects the slack of the rope based on a comparison result of the movement of the rope detected in the first detection part 21 with the operation of the winch device detected in the second detection part 22.SELECTED DRAWING: Figure 1

    【課題】予め多様な物理量を求めることなく、ウインチ装置から繰り出されるロープの緩みを検知できるロープ緩み検知装置を提供する。【解決手段】ロープ緩み検知装置2は、第1検出部21と、第2検出部22と、緩み検知部23とを備えている。第1検出部21は、ウインチ装置から繰り出されたロープの経路上において、ロープの繰り出し方向におけるロープの移動を検出する。第2検出部22は、ウインチ装置の動作を検出する。緩み検知部23は、第1検出部21で検出されたロープの移動と、第2検出部22で検出されたウインチ装置の動作との比較結果に基づいて、ロープの緩みを検知する。【選択図】図1
