To provide a suspended load turning apparatus capable of reliably limiting turning speed of suspended load even when disturbance such as wind occurs.SOLUTION: There is provided a suspended load turning apparatus 10 comprising a flywheel 11, a flywheel rotating electric motor 12 for driving the flywheel 11, a gimbal 13 for pivotally supporting the flywheel 11, and a gimbal inclining electric motor 14 for driving the gimbal 13, the apparatus causing suspended load 50 to turn by a gyroidal effect generated when the gimbal 13 is inclined while rotating the flywheel 11. The apparatus is provided with turning speed controlling means 15 for suppressing increase in the turning speed of the suspended load 50 by, when an inclination torque T of the gimbal inclining electric motor 14 exceeds a limiting value Tr, holding input current to the gimbal inclining electric motor 14 with the value at that time, and suspending the inclination by the gimbal inclining electric motor 14.SELECTED DRAWING: Figure 1
【課題】風等の外乱が生じた場合であっても、吊荷の旋回速度を確実に制限することができる吊荷旋回装置を提供する。【解決手段】フライホイール11と、フライホイール11を回転駆動するフライホイール回転用電動機12と、フライホイール11を軸支するジンバル13と、ジンバル13を傾転駆動するジンバル傾転用電動機14とを備え、フライホイール11を回転させながらジンバル13を傾転させたときに生じるジャイロ効果によって、吊荷11を旋回させるようにした吊荷旋回装置10において、ジンバル傾転用電動機14の傾転トルクTが制限値Trを超えると、ジンバル傾転用電動機14への入力電流をそのときの値で保持して、ジンバル傾転用電動機14による傾転を停止することで、吊荷50の旋回速度の上昇を抑える旋回速度制御手段15を設けた。【選択図】 図1
