To provide an oscillation reduction sling guide system capable of reducing the oscillation of a suspending cargo caused in a dynamic lift off.SOLUTION: The oscillation reduction sling guide system for reducing the oscillation of a suspending cargo of a crane, includes an arithmetic unit calculating an offset distance that is an amount of outward deflection from a rotation center on a horizontal plane on a head end of a boom caused by a load of the suspending cargo when the suspending cargo is suspended to a target position from the ground surface by winding up a rope by using a dynamic model of a crane. The arithmetic unit presents a position on the horizontal plane when the suspending cargo is horizontally moved by the offset direction toward the rotation center from the position on the horizontal plane of the mass center as an oscillation reduction sling position that should be a position on the horizontal plane of the head end of the boom before the slinging.SELECTED DRAWING: Figure 10

    【課題】地切り時に発生する、吊り荷の揺動を低減することができる減揺玉掛ガイドシステムを提供する。【解決手段】クレーンにおける、吊り荷の揺動を低減するための減揺玉掛ガイドシステムは、クレーンの力学モデル用いて、ロープを巻き上げて吊り荷を地面から目標位置まで吊り上げたときの吊り荷の荷重によるブームの先端の水平面における回転中心から外側へのたわみ量であるオフセット距離の計算を行う演算装置を備え、演算装置は、吊り荷の質量中心の水平面における位置から回転中心の方にオフセット距離だけ水平移動させたときの水平面における位置を玉掛前のブームの先端の水平面における位置とすべき減揺動玉掛位置として提示する。【選択図】図10
