PROBLEM TO BE SOLVED: To provide a device that guides a derricking rope loosened due to a boom being fanned by wind to an appropriate position.SOLUTION: A rope guide device 500 is a guide device for a derricking rope 112 wound around a first sheave group 231 and a second sheave group constituting a derricking device for derricking a boom of a crane, which has a plurality of partitioning portions arranged outward in a radial direction between adjacent sheaves of a plurality of sheaves S constituting the first sheave group, a first connection portion 512 and a second connection portion 513, and comprises a first regulating member 510 and a second regulating member 560 which regulate movement of the derricking rope between the adjacent sheaves. The first connection portion and the second connection portion are arranged at positions which do not disturb motion of the derricking rope during turning of the boom from a lower limit position to an upper limit position. A space between the adjacent partitioning portions is set as a space where the derricking rope is permitted to move during the turning of the boom from the lower limit position to the upper limit position.SELECTED DRAWING: Figure 10

    【課題】強風によりブームがあおられることに起因して弛んだ起伏ロープを適正な位置に案内する装置の提供。【解決手段】ロープ案内装置500は、クレーンのブームを起伏させる起伏装置を構成する第1シーブ群231と第2シーブ群との間に掛け回された起伏ロープ112の案内装置であって、第1シーブ群を構成する複数のシーブSの隣り合うシーブ間の径方向外方に配置される複数の仕切部と、第1連結部512と、第2連結部513とを有し、起伏ロープが隣り合うシーブ間で移動することを規制する第1規制部材510,及び第2規制部材560を備え、第1連結部および第2連結部は、ブームが下限位置から上限位置まで回動する間、起伏ロープの動作を妨げない位置に配置され、隣り合う仕切部間は、ブームが下限位置から上限位置まで回動する間、起伏ロープが移動することを許容する空間とされている。【選択図】図10
