PROBLEM TO BE SOLVED: To provide a controller for hook transfer in carne capable of simple carrying out operation of an air actuator in preference which allows a suspended load to be quickly transferred to a targeted position. SOLUTION: The controller for hook transfer in carne is characterized in comprising an operation detecting sensor 22 for detecting transfer direction and travel of the hook 4 by means of an operations means, a boom length sensor 20, a boom derricking angle sensor 21, and an arithmetic unit 27, wherein the arithmetic unit 27 is configured such that it computes operation speed of each drive means so as to preferentially drive a telescopic drive means or derricking drive means allowing the hook 4 to be transferred along the working radius of the telescopic boom based on the state of the telescopic boom, and outputs a signal of the operation speed to the corresponding telescopic drive means or derricking drive means.
