Abstract
A crane is provided. The crane includes an acceleration sensor that detects the acceleration of a load, wherein a target velocity signal is converted into target location coordinates of the load, current location coordinates of a boom are calculated from a slewing angle, a luffing angle, and an expansion/contraction length, the spring constant of a wire rope is calculated from the previously calculated location of the load from a unit time earlier, the current location coordinates of the boom, and the current accelerations of the load as detected by the acceleration sensor, target location coordinates of the boom are calculated from the accelerations, the spring constant, and the target location coordinates of the load, and an actuator operation signal is generated.
