To provide an oscillation control device for a lifting machine that can control the oscillation motion of a load and transport the load in a stable state.SOLUTION: In an oscillation control device 4, the rotation axis directions of propellers 61P, 62P, 63P, and 64P of a thrust part 6 are orthogonal to the direction in which a wire rope 32 extends in lateral view. A total of four thrust parts 6 are installed in equal phase around a hook 33. A first thrust part 61 and a third thrust part 63, which are paired so as to sandwich the hook 33, generate thrust in opposite directions. A second thrust part 62 and a fourth thrust part 64, which are paired so as to sandwich the hook 33, generate thrust in opposite directions. Further, the thrust by the first thrust part 61 and the third thrust part 63 and the thrust by the second thrust part 62 and the fourth thrust part 64 generate rotational forces in mutually opposite directions. When applying translational force and rotational force to the hook 33, the thrusts of a maximum of three of the four thrust parts 6 are used.SELECTED DRAWING: Figure 2

    【課題】荷物の揺動運動を制御でき、荷物を安定させた状態で搬送することが可能となる揚重機の揺動制御装置を提供する。【解決手段】揺動制御装置4においては、推力部6のプロペラ61P・62P・63P・64Pの回転軸方向はワイヤロープ32が延びる方向と側面視において直交し、フック33を中心に計四つの推力部6が等しい位相で取り付けられ、フック33を挟み込むように対をなす第一推力部61と第三推力部63が互いに反対方向に推力を発生させ、フック33を挟み込むように対をなす第二推力部62と第四推力部64が互いに反対方向に推力を発生させ、更に第一及推力部61及び第三推力部63による推力と第二推力部62及び第四推力部64による推力が互いに反対方向に回転力を発生させ、フック33に対して並進力と回転力を付与する際には、計四つの推力部6のうちの最大三つの推力を利用する。【選択図】図2
