Provided is a crane capable of allowing an operator to recognize an error in work information or in a number of windings set in a safety device. A main tension of a main wire rope is calculated from a main output torque of a main winch, a sub output torque of a sub winch , a main drum winding radius of the main winch, and a sub drum winding radius of the sub winch. An estimated hanging load, which is calculated from the main tension, a sub tension of a sub wire rope and the number of windings of the wire rope set in a safety device, is compared with an actual hanging load calculated from fluctuating thrust force and boom information. Thus, the suitability of a work kind or a winding number set in the safety device is determined.
