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
