A crane comprising: a crane main body; a boom supported by the crane main body so as to be swingable around a horizontal first rotation axis; a jib having a base end portion supported at a front end portion of the boom so as to be swingable around a second rotation axis parallel to the first rotation axis and a front end portion on a side opposite to the base end portion; a boom driving unit which causes the boom to swing in a rise direction and a fall direction around the first rotation axis; a jib driving unit which causes the jib to swing in the rise direction and the fall direction around the second rotation axis; a manipulation unit which accepts manipulation for driving the boom and the jib; a drive control unit which outputs a drive signal for controlling the boom driving unit and the jib driving unit according to the manipulation input to the manipulation unit; and a suspension device which is suspended from the front end portion of the jib and connected to a suspended load, characterized by an angle condition determination unit which determines whether a jib boom angle condition is established or not, the jib boom angle condition being established in a case where a jib offset angle (θm) as an angle defined by an extension of a center line of the boom and a center line of the jib when viewed from a direction parallel to the second rotation axis is larger than a threshold value angle (θs) formed of an acute angle set in advance; and an operation regulating unit which regulates swinging of the boom and the jib according to a mode set in advance, the operation regulating unit having an ordinary work mode and a self-erecting and falling mode, and regulating, in the ordinary work mode, swinging of the boom and the jib so that the front end portion of the jib is included in a work allowable range at a work posture of the crane at which the boom rises with respect to the crane main body and the jib rises with respect to the boom, the work allowable range being set according to a weight of the suspended load, and allowing, in the self-erecting and falling mode, the front end portion of the jib to enter an outside of the work allowable range irrespective of the weight of the suspended load, as well as allowing the crane to change a posture between a fall posture, at which the boom and the jib fall forward of the work posture and the front end portion of the jib lands on the ground, and the work posture according to a determination result of the angle condition determination unit. a crane main body;
