Abstract:
A crane is provided. A slewing base camera detects a load W that is suspended by a wire rope, the current coordinate location of the load is calculated from the location of the detected load, the current coordinate location of a tip end of a boom is calculated from the position of a crane, a target velocity signal that was inputted from a manipulation tool is converted into a target coordinate location of the load, a wire rope direction vector is calculated from the current coordinate location of the load and the target coordinate location of the load, a target location of the tip end of the boom for the target coordinate location of the load is calculated from a wire rope reel-out amount and the wire rope direction vector, and an actuator operation signal is generated.
