CONSTITUTION: An unmanned carrier 40 is run toward a crane 10 at a high speed. When the carrier 40 enters the radio communication range of the crane 10, the carrier receives three signals, namely, the current position of the crane 20, on-floor position of a concrete bucket 24, and on-floor status signal. A controller stores the three signals. When the bucket 24 is not put on a floor, the controller calculates the expected on-floor position of the bucket 24 from the current position of the crane 20 (the position of the revolving center of the revolving body 22) and stores the calculated expected on-floor position of the bucket 24. When the bucket 24 is put on a floor, the on-floor position of the bucket 24 is set as the target position for the carrier. When the difference between the current position of the carrier 40 detected by a running position detector 45 and the expected on-floor position of the bucket 24 becomes smaller than the first prescribed distance, decelerating operations are started and the carrier is decelerated. When the speed of the carrier 40 becomes an intermediate speed as a result of the deceleration and the on-floor status signal indicates that the bucket 24 is put on the floor, the deceleration is stopped and the carrier is run at the intermediate speed.
