PROBLEM TO BE SOLVED: To promptly and highly accurately measure a centroid position of a load without using a radiation source.SOLUTION: A connector (50) is included which has a rotary shaft (52) on a perpendicular axis passing the center of a plane formed from hanging points (71-74) of a hanging tool (hanging beam 42) of a cargo handling machine (container crane 20) and in the state where rotation of the connector (50) is restricted, centroid positions of loads (12, 12a and 12b) in a horizontal direction are measured. The restriction of the rotary shaft (52) of the connector (50) is then canceled, the loads (12, 12a and 12b) are vibrated and axial vibration of the rotary shaft (52) is measured, thereby measuring centroid positions of the loads (12, 12a and 12b) in a vertical direction. |
