To provide a torque controller capable of accurately controlling the torque of a cable reel 8 which delivers a power feeding cable 9 to, for example, a crane hanging tool 7 by being able to accurately calculate the cable length delivered from a cable reel 8.SOLUTION: A torque controller controls the torque of a cable reel 8 based on the wound diameter of a cable 9 corresponding to the integrated rotation angle from the origin of the cable reel 8, based on the delivery length of the cable 9 corresponding to the integrated rotation angle of the cable reel 8 and to the winding diameter of the cable 9, based on the weight of the delivered cable 9 corresponding to the delivery length of the cable 9, and based on the weight of the delivered cable 9 and on the winding diameter of the cable 9.SELECTED DRAWING: Figure 1

    【課題】例えばクレーン吊り具7への給電用ケーブル9を繰り出すケーブルリール8のトルク制御を、ケーブルリール8から繰り出された長さが正確に算出できることによって、正確に行うことができるトルク制御装置を提供する。【解決手段】ケーブルリール8の原点位置からの積算回転角度に対応するケーブル9の巻径に基づき、ケーブルリール8の積算回転角度及びケーブル9の巻径に対応するケーブル9の繰り出し長さに基づき、ケーブル9の繰り出し長さに対応する繰り出されたケーブル9の重量に基づき、繰り出されたケーブル9の重量及びケーブル9の巻径に基づいて、ケーブルリール8のトルク制御を行う。【選択図】図1
