To provide a suspended load swing suppression device that suppresses the swing of a suspended load suspended from a crane to improve the work efficiency even when a work ship is oscillated by ocean waves.SOLUTION: A suspended load swing suppression device 1 includes a swing prediction system 11 predicting future-estimated swing of a work ship from the present time and a winch control system 12 that is connected to a winch 10 to control the rotation speed of the winch 10 based on a signal from the swing prediction system 11. The winch control system 12 includes an engine 25, an arithmetic unit 26 calculating the rotation speed of the winch 10 based on a signal from the swing prediction system 11, and a torque converter 27 controlling the rotation speed transmitted to the winch 10 via a deceleration mechanism 32 from a rotation shaft 25A of the engine 25 based on a signal from the arithmetic device 26. Therefor, the swing of the suspended load can be suppressed to improve the work efficiency even when the work ship is oscillated by ocean waves.SELECTED DRAWING: Figure 1

    【課題】作業船が波浪により動揺しても、クレーンから吊り下げられる吊荷の動揺を抑制して作業効率を向上させる吊荷動揺抑制装置を提供する。【解決手段】本吊荷動揺抑制装置1は、作業船の現時点から先の動揺を予測する動揺予測システム11と、ウインチ10に連結され、動揺予測システム11からの信号に基づいて、ウインチ10の回転速度を制御するウインチ制御システム12と、を備え、該ウインチ制御システム12は、エンジン25と、動揺予測システム11からの信号に基づいて、ウインチ10の回転速度を演算する演算装置26と、該演算装置26からの信号に基づき、エンジン25の回転軸25Aから減速機構32を経由してウインチ10に伝達される回転速度を制御するトルクコンバータ27と、を備えている。これにより、作業船が波浪により動揺しても、吊荷の動揺を抑制して作業効率を向上させることができる。【選択図】図1
