Abstract
A target trajectory signal is calculated by integrating a target speed signal inputted from a suspended-load moving operation tool and passing the integrated signal through a lowpass filter. Target position coordinates of a load are calculated from the target trajectory signal. The current position coordinates of a leading end of a boom are calculated from the attitude of a crane device. An unwinding amount of a wire rope is calculated from the current position coordinates of the load and the current position coordinates of the boom. A direction vector of the wire rope is calculated from the current position coordinates of the load and the target position coordinates of the load. Target position coordinates of the boom are calculated from the unwinding amount and the direction vector. An actuation signal of an actuator is generated from the target position coordinates of the boom.
