Zusammenfassung:	PURPOSE:To provide the control method of a crane which improves the delay for the acceleration target, suppresses the effect of the swing of a wire, and improves the control precision. CONSTITUTION:In a crane suspending a wire 3 from a horizontally moving trolley 1 to hoist a baggage 4, the acceleration target value of the trolley 1 is integrated by a control system following the acceleration target pattern of the trolley 1, the difference between the acceleration integrated value and the trolley speed measured value is obtained as the differential speed, and the sum of three values: the constant times the differential speed, the constant times the speed difference integrated value, and the constant times the acceleration target value, or the sum of four values added with the speed measured value is used as the driving force to control the trolley 1.
