Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control method for an arc-moving type cable crane which automatically controls the operation and effectively suppresses the deflection of a bucket in accelerating and decelerating a lateral trolley. SOLUTION: The behavior of a moving tower 3, a main rope 7, a lateral trolley 9, and a bucket 12 is analyzed according to the carrier start position and a carrier completion position of the bucket 12 with the traveling distance of the traveling tower 3, the delivery length of a lateral rope, the delivery length of a sling 11, the traveling speed of the moving tower 3, the delivery speed of the lateral rope 10, and the delivery speed of the sling 11 set as the calculation elements so as to model the operation patterns, a modeled operation pattern is selected according to the set conditions in driving the cable crane 50, the cable crane 50 is automatically controlled according to the operation pattern, and the deflection of the bucket 12 is offset by a feedback control in accelerating and decelerating the lateral trolley 9.
