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. An upper spreader-side mounting hole 65 of the upper spreader 60, into which a mounting pin 90 can be inserted, is arranged at a position which overlaps with a center shaft 70a (a center shaft) of a part 70 to be guided when viewed from a spreader lateral direction Ys. A mounting hole 89 at the mounting part side of the mounting part 80, into which the mounting pin 90 can be inserted, is arranged at a position adjacent to the mounting hole 65 at the upper spread side when the part 70 to be guided contacts a guide part 83 and a regulating part 85.SELECTED DRAWING: Figure 5
【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。上部スプレッダ60の上部スプレッダ側取付孔65は、取付ピン90を差し込み可能であり、スプレッダ横方向Ysから見て被ガイド部70の被ガイド部中心軸70a(中心軸)と重なる位置に配置される。取付部80の取付部側取付孔89は、取付ピン90を差し込み可能であり、ガイド部83および規制部85に被ガイド部70が接触したときに、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5
