Abstract
A deflection device allows deflection correction control of suspended cargo for deflections having both parallel deflection and skew deflection components. The suspended cargo is held by a suspension tool suspended from a trolley via ropes and is carried together with movement of the trolley. The device has mark detectors provided under the trolley with a range of vision facing downwardly and a corresponding plurality of marks provided opposite of the mark detectors on the suspension tool. A picture processing device generates picture signals of the first and second marks detected by the mark detectors. A deviation amount computing device calculates the deviation of the first and second marks, and a deflection amount calculating device calculates the amount of parallel deflection and the amount of skew deflection based on the computed deviation amount.
