To facilitate alignment of a mounting hole for mounting an upper spreader on a derricking member.SOLUTION: An upper spreader mounting device 50 comprises an upper spreader 60 and a mounting part 80. The mounting part 80 comprises a guide part 83 that guides a part 70 to be guided, a regulating part 85 that regulates movement of the part 70 to be guided, and a rotation stopping part 87 that restricts rotation of the upper spreader 60 with a lateral direction Y as a rotation shaft. A mounting hole 89 at the mounting part side is arranged at a position adjacent to a mounting hole 65 at the upper spreader side of the upper spreader 60 when the part 70 to be guided contacts the guide part 83 and the regulating part 85 and the upper spreader 60 contacts the rotation stopping part 87.SELECTED DRAWING: Figure 3

    【課題】起伏部材に上部スプレッダを取り付けるための取付孔の位置合わせを容易に行えるようにする。【解決手段】上部スプレッダ取付装置50は、上部スプレッダ60と、取付部80と、を備える。取付部80は、被ガイド部70をガイドするガイド部83と、被ガイド部70の移動を規制する規制部85と、横方向Yを回転軸とする上部スプレッダ60の回転を規制する回転止め部87と、を備える。取付部側取付孔89は、ガイド部83および規制部85に被ガイド部70が接触し、回転止め部87に上部スプレッダ60が接触したときに、上部スプレッダ60の上部スプレッダ側取付孔65と合う位置に配置される。【選択図】図3
