PROBLEM TO BE SOLVED: To provide a winch lifting method and a winch lifting device for lifting and recovering a person needed to be rescued capable of easily and stably lifting an object drifting on a water surface with a lifting and recovering net.SOLUTION: A winch lifting method for lifting and recovering a person needed to be rescued that, by the rotation of a motor 15, moves a lifting and recovering net 17 in a lifting direction with respect to a water surface W1 through a wire 16 includes: a speed control mode for moving the lifting and recovering net 17 by performing speed control so as to control the motor 15 to be a predetermined speed; a first torque control mode for holding the lifting and recovering net 17 on the water surface W1 by performing torque control of the motor 15 so as to acquire torque output that can maintain the wire 16 in a tension state; and a second torque control mode for elevating the lifting and recovering net 17 in the water W2 by performing torque control of the motor 15 so as to acquire torque output smaller than the torque in the first torque control mode.

    【課題】水面上に漂っている物体を揚収ネットにより水面上から容易かつ安定に引き上げることができる要救助者揚収ウィンチ昇降方法及び昇降装置を提供する。【解決手段】モータ15の回転により索16を介して揚収ネット17を水面W1に対して昇降方向に移動させる要救助者揚収ウィンチ昇降方法において、モータ15を所定速度となるように速度制御することによって、揚収ネット17を移動させる速度制御モードと、索16を緊張状態に維持可能なトルク出力となるように、モータ15をトルク制御することによって、揚収ネット17を水面W1上に保持する第1トルク制御モードと、第1トルク制御モードにおけるトルクより小トルク出力となるように、モータ15をトルク制御することによって、揚収ネット17を水中W2で上昇させる第2トルク制御モードとを備える。【選択図】図1
