[Problem] To provide a controller making it possible to prevent the occurrence of irregular winding and damage to a latch fitting in automatic deployment and automatic stowing of a boom. [Solution] This controller uses the length L of a boom, an A and B (first designated values) indicating coordinates of a latch fitting, and a length K (second designated value) that is the sum of the length of a hook block and the length of a latch fitting as well as a derricking angle θ of the boom to generate a theoretical wire feed length X1(θ) at an orientation where the hook block is hoisted up and a theoretical wire feed length X2(θ) at an orientation where the hook block is put down (S14). After the wire is wound up and stretched, the controller feeds out wire commensurate with a target value that is the mean value of X1(θ) and X2(θ) (S19), and brings the hook block to an intermediate orientation between the hoisted-up orientation and the put-down orientation. The controller derricks the boom and drives a winch so as to maintain the intermediate orientation.

[Problem] To provide a crane device with which it is possible to automatically identify the number of times a wire is to be wrapped before crane work. [Solution] This controller lowers a boom through a first predetermined angle (S21 to S24). The wire slackens by a length corresponding to the first predetermined angle. The amount of wire slack depends on the number of times the wire is wrapped. This controller winds up the slack wire and acquires the total number of output pulses, which indicates the length of the wire wound up. A memory stores in advance a correspondence table in which the total number of output pulses and the number of times the wire is wrapped have been associated. The controller identifies, as the current number of times the wire is wrapped, the number of times the wire is wrapped associated with the acquired total number of output pulses, and causes the memory to store the identified number of times the wire is wrapped.
