A crane comprises a boom and two independently operable hoisting cable winches, each configured with a hoisting cable guided over the boom. Each hoisting cable carries a load suspension means for fastening a load. The crane comprises a lifting device having an upper part pivotably attached to the boom, and a lower part connected to the upper part pivotably about a horizontal pivot axis, with axes of rotation parallel to the pivot axis. The hoisting cables are each guided over first and second deflection pulleys and attached to the lower part at their free ends. The deflection pulleys and pivot axis are arranged such that, by asynchronous actuation of the hoisting cable winches while performing a pivoting movement of the lower part relative to the upper part, a load connected to both load suspension means can be rotated about a load pivot axis running parallel to the pivot axis.
