Center of gravity detection device and center of gravity detection method

摘要

An object of the present invention is to easily detect an eccentric amount of a lifting position with respect to a center of gravity of an object. A center-of-gravity detecting device includes a first detector for detecting a lifting force when a target object is constantly lifted by a crane device, and a lifting force T detected by the first detector. The differential value D and the average value DA calculated by the differential value calculation unit 61 are compared with the differential value D and the average value DA of the differential value D, which is the amount of change per time, and the differential value D is calculated. And a lifting force Tb detected by the first detector 11 when the determination unit 62 determines that the differential value D has decreased below the average value DA. And an eccentricity calculator 63 for calculating the eccentricity of the lifting position with respect to the horizontal center of gravity of the object 200 from the center.
