PROBLEM TO BE SOLVED: To provide a structure for preventing entanglement of a wire rope for a crane device, which can prevent a plurality of vertically-extended parts from getting entangled with one another even when there is a large space between a boom tip and a hook block hanging a cargo.SOLUTION: A structure for preventing entanglement of a wire rope for a crane device comprises a space maintenance member 50 for maintaining spaces among a plurality of vertically-extended parts 22a of a wire rope 22. The space maintenance member 50 vertically moves between a boom head 21b and a hook block 24 depending on a change in the space between the boom head 21b and the hook block 24.SELECTED DRAWING: Figure 4
【課題】荷物を吊り下げたフックブロックとブームの先端部との間隔が大きい場合においても複数の上下延伸部が互いに絡み付くことを防止することが可能なクレーン装置のワイヤロープ絡まり防止構造を提供する。【解決手段】ワイヤロープ22の複数の上下延伸部22aの間隔を保持するための間隔保持部材50を備え、間隔保持部材50が、ブームヘッド21bとフックブロック24との間隔の変化に応じて、ブームヘッド21bとフックブロック24との間を上下方向に移動する。【選択図】図4
