PROBLEM TO BE SOLVED: To provide a turning/translating control device for a suspended cargo which can easily damp swing in a turning direction and in a translating direction of a suspended cargo in short time.SOLUTION: A turning/translating control device 10 for a suspended cargo which damps swing in turning and translating directions acting on a suspended cargo 12 comprises: turning control means 20 having a gyro-actuator which suppresses reaction which is generated when turning the suspended cargo with turning means for the suspended cargo 12; translating control means 40 that has active mass translating units which move back and forth an active mass 46 on a linear rail 42 and suppresses swing in a translating direction acting on the suspended cargo by arranging an intersection point, where the two active mass translating units are crossed, below a hook 84 and moving back and forth the active mass 46; a detection sensor for acceleration and inclination angles of the suspended cargo; and control means 70 that activates the turning control means 20 or the translating control means 40 on the basis of measured values of the acceleration and inclination angles of the suspended cargo so as to damp the swing in the turning and translating directions acting on the suspended cargo.SELECTED DRAWING: Figure 1
【課題】短時間で容易に吊荷の旋回方向及び併進方向の揺れを減衰する吊荷の旋回・併進制御装置を提供する。【解決手段】吊荷12に作用する旋回又は併進方向の揺れを減衰させる吊荷の旋回・併進制御装置10において、吊荷12の旋回手段によって吊荷を旋回させたときに生じる反力を抑制するジャイロアクチュエータを有する旋回制御手段20と、リニアレール42上でアクティブマス46を進退移動させるアクティブマス併進ユニットを有し、2つの前記アクティブマス併進ユニットを直交させた交点をフック84下に配置し前記アクティブマス46を進退移動させて吊荷に作用する併進方向の揺れを抑制する併進制御手段40と、吊荷の加速度及び傾斜角度の検出センサーと、吊荷の加速度および傾斜角度の測定値に基づいて前記旋回制御手段20又は前記併進制御手段40を作動させて吊荷に作用する旋回又は併進方向の揺れを減衰させる制御手段70と、を備える。【選択図】図1
