To suspend an object in a stable state.SOLUTION: A second grip and a connection part of a gripping unit 1401 are inserted into openings OP1,2 formed in an object WK from outside the object WK, and a second grip 142 and a connection part 143 of a gripping unit 1402 are inserted into openings OP2,2 formed in an object from outside the object WK. After the insertion, the orientations of the gripping units 1401 and 1402 are changed to transit from a first attitude allowing the second grip 142 to be taken out through the openings OP1,2 and OP2,2 to a second attitude not allowing the second grip 142 to be taken out through the openings OP1,2 and OP2,2. In this state, when a suspension tool 100 rises, the first grips 141 of the gripping units 1401 and 1402 are engaged with the openings OP1,2 and OP2,2 from outside the object WK to grip the object WK. The second grips 142 of the gripping units 1401 and 1402 are engaged with the openings OP1,2 and OP2,2 from inside the openings OP1 and OP2 to grip the object WK.SELECTED DRAWING: Figure 8
【課題】安定した状態で物体を吊り下げる。【解決手段】把持部1401の第2把持部及び接続部を物体WKに形成された開口OP1,2に物体WK外側から挿入し、把持部1402の第2把持部142及び接続部143を物体に形成された開口OP2,2に物体WK外側から挿入する。当該挿入後に、把持部1401,1402の向きを変えて、第2把持部142を開口OP1,2,OP2,2から取り出し可能な第1姿勢から、第2把持部142を開口OP1,2,OP2,2から取り出し不可の第2姿勢へと遷移させる。この状態から、吊具100が上昇すると、把持部1401,1402の第1把持部141が物体WK外側から開口OP1,2,OP2,2に係合して物体WKを把持する。また、把持部1401,1402の第2把持部142が開口OP1,OP2内部側から開口OP1,2,OP2,2に係合して物体WKを把持する。【選択図】図8
