PROBLEM TO BE SOLVED: To provide a lifting device capable of being returned to a condition where next hanging load work is possible automatically when hanged down as well as of correcting a position of that hanging load to a horizontal state easily and exactly on lifting a hanging load such as a container etc by a crane.SOLUTION: Several cables which has a definite length to have an upper end hanged by a crane and to couple a lower end to both ends of the hanging load detachably, a correction mechanism 3 which has a liquid pressure cylinder 4a arranged in these cables to extend the piston rod 4a3 to correct an inclination of the hanging load to a horizontal state when the hanging load hanged by a crane inclines and a tension spring 8a which is always attached to the liquid pressure cylinder 4a in a direction where the piston rod 4a3 is retracted and makes the piston rod 4a3 return to an original position when there is no load of the hanged load are provided.SELECTED DRAWING: Figure 2

    【課題】クレーンによってコンテナ等の吊荷を吊り上げる際に、その吊荷の姿勢を簡単、且つ正確に水平状となるように補正することができると共に、吊り下ろした際に、自動的に次の吊荷作業が可能な状態に復帰させることができる吊荷の吊り上げ装置を提供する。【解決手段】上端をクレーンによって吊支させ、下端を吊荷の両端部に着脱自在に連結する一定長さを有する数本の索条と、これらの索条に設けられてクレーンにより吊り上げた吊荷が傾いた際に、そのピストンロッド4a3を伸長させて吊荷の傾きを水平状態に補正する液圧シリンダ4aを有する補正機構3と、上記液圧シリンダ4aに、そのピストンロッド4a3を収縮させる方向に常時付勢して吊荷の荷重が無くなった時に上記伸長しているピストンロッド4a3を元の位置に復帰させる引張りスプリング8aを設けている。【選択図】図2
