To provide a suspended load turning system capable of suppressing the swing in a turning direction of a suspended load and the twisting of a rope even when the suspended load suspended from a crane is turned around a vertical axis line.SOLUTION: A control device 20 of a suspended load turning system 1 includes a motor part 12 rotating a suspended load 3 around a vertical axis line 2c, and a clutch part 13 transmitting or cutting off the power of the motor part 12 to the suspended load 3. The control device derives a driving pattern of the motor part 12 and a switching timing of the clutch part 13 until a turning angle of the suspended load 3 reaches a target turning angle by using a mathematical model showing a turning movement of the suspended load 3 in the case where the clutch part 13 is in an ON-state or OFF-state.SELECTED DRAWING: Figure 2
【課題】クレーンから吊り下げられた吊り荷を垂直軸線周りに回動させる場合においても、吊り荷の回動方向の振れやロープの捻れを抑制できる吊り荷回動システムを開示すること。【解決手段】吊り荷3を垂直軸線2c周りに回動させるモータ部12及びモータ部12の動力を吊り荷3へ伝達または遮断するクラッチ部13を備えた吊り荷回動システム1の制御装置20は、クラッチ部13がオン状態である場合及びオフ状態である場合の吊り荷3の回動運動を表した数理モデルを用いて、吊り荷3の回動角度が目標回動角度に到達するまでの、モータ部12の駆動パターン、及び、クラッチ部13の切替タイミングを導出する。【選択図】 図2
