To provide a crane device that finds out the number of wire hangings before crane work is carried out.SOLUTION: A control program drives a winch in a direction to wind a suspending wire rope (S15). Force applied to the winch and force received by an undulating cylinder 52 from a boom 22 change when the suspending wire rope is wound up. The force applied to the winch by the suspending wire rope and the force received by the undulating cylinder 52 from the boom 22 are detected by a second sensor 64 and a first sensor 63 (S16). The control program finds out a number of wire hangings on the basis of a first detected power and a second detected power detected by the second sensor 64 and the first sensor 63, and constants and arithmetic expressions stored in a memory 72 (S18) in advance. The control program determines speed at which the winch 23 unwinds the suspending wire rope based on the specified number of wire hangings and the rising speed of the boom (S20).SELECTED DRAWING: Figure 7
