Abstract (en)
Provided is a crane capable of effectively suppressing the swing of the suspended object when the work to transport the suspended object is stopped. A crane (1) includes a boom (2) and a suspended object 16 suspended from the boom (2). The crane (1) is configured to perform, when in plane coordinates as seen vertically downward from above the crane, a position where the suspended object 16 is suspended from the boom (2) without swinging is defined as a reference position of the suspended object 16, a first control to operate, in a case where the suspended object 16 is at a first shifted position 16a1 shifted with respect to a first reference position, the boom 2 to approach the first shifted position 16a1 in the plane coordinates, and a second control to operate, in a case where the suspended object 16 is at a second shifted position 16a2 shifted from a second reference position that is a reference position after the first control, the boom 2 to approach the second shifted position 16a2 in the plane coordinates.
