To reduce labor and time required for work to mount an upper spreader to an undulating member.SOLUTION: A mounting pin 90 connects an upper spreader 30 to a mounting portion 50 by being inserted into an upper spreader side mounting hole 35 and a mounting portion side mounting hole 75. The mounting portion 50 is provided on a boom 13, is capable of mounting the upper spreader 30, and is configured to be able to change a pin mounting position P1 in a position adjustment direction D2. The pin mounting position P1 is the position where the mounting pin is attached to the mounting hole 75 on the side of the mounting portion. The position adjustment direction D2 is a direction including at least one of a boom height direction Zb (height direction of the boom 13) and a boom longitudinal direction Xb (longitudinal direction of the boom 13).SELECTED DRAWING: Figure 3

    【課題】上部スプレッダを起伏部材に取り付ける作業にかかる手間および時間を抑制する。【解決手段】取付ピン90は、上部スプレッダ側取付孔35と取付部側取付孔75とに差し込まれることで取付部50に上部スプレッダ30を接続する。取付部50は、ブーム13に設けられ、上部スプレッダ30を取り付け可能であり、ピン取付位置P1を位置調整方向D2に可変に構成される。ピン取付位置P1は、取付部側取付孔75への取付ピンの取り付け位置である。位置調整方向D2は、ブーム高さ方向Zb(ブーム13の高さ方向)およびブーム長手方向Xb(ブーム13の長手方向)の少なくともいずれかを含む方向である。【選択図】図3
