To provide a crane attachment used by its being coupled to a spreader when an open type container is loaded, the crane attachment being able to reduce labor needed to place the container on the ground.SOLUTION: A crane attachment has: a frame structure 2 having four column parts 2a extending in a vertical direction; a coupling mechanism 3 by which the frame structure 2 is coupled to a spreader of a container crane so as to be detachable; a twist lock pin 4 projecting downward from a lower end of each column part 2a; a rotary coupling part 5 provided at a lower part of each column part 2a; and a support receiving member 6 coupled to each column part 2a via the rotary coupling part 5 so as to be rotatable. By means of the rotary coupling part 5, the support receiving member 6 is movable to a first position where the lower end of the support receiving member 6 is located higher than a lower end of the twist pin 4 and to a second position where the lower end of the support receiving member 6 is located lower than the lower end of the twist lock pin 4.SELECTED DRAWING: Figure 3

    【課題】開放型コンテナを荷役する際にスプレッダに連結して使用されるクレーン用アタッチメントにおいて、地面に載置する作業の軽労化を図ることができるクレーン用アタッチメントを提供する。【解決手段】上下方向に延在する4本の柱部2aを有するフレーム構造体2と、フレーム構造体2をコンテナクレーンのスプレッダに着脱可能に連結する連結機構3と、それぞれの柱部2aの下端から下方に突出したツイストロックピン4と、それぞれの柱部2aの下部に設けられた回動連結部5と、回動連結部5を介してそれぞれの柱部2aに回動可能に連結された支持受部材6とを有する構成とし、支持受部材6を回動連結部5により、支持受部材6の下端がツイストロックピン4の下端よりも上方に位置する第1位置と、支持受部材6の下端がツイストロックピン4の下端よりも下方に位置する第2位置とに移動可能な構成とする。【選択図】図3
