ABSTRACT:
A crane provided with a trolley, a hanging member, a rope member, and a hoisting device. The crane includes a horizontal position displacement detection unit which detects a horizontal positional displacement between at least two corners of the cargo and a landing place of the two corners; and a horizontal position displacement correction unit which corrects a horizontal positional displacement between the at least two corners of the cargo and the landing place of the two corners when the two corners have landed based on a detection signal from the horizontal position displacement detection unit. The horizontal position displacement correction unit corrects the position of a corner of the cargo so that the corner lands at the landing place of the corner, and then corrects the position of another corner so that the corner lands at the landing place of the corner.
