To solve the problems of conventional technology, that is to provide a hanging jig and hanging jig set, a lifting device, which can easily grip a suspended load as compared with the conventional technique without newly attaching a perforated locking tool, and a lifting method using the lifting device.SOLUTION: The hanging jig of the present invention includes a gripping body, an auxiliary body, and an upper connecting body. Of these, the right end of a left grip arm and the left end of a right grip arm are hinged, and the left grip arm and a left auxiliary arm are hinged. The right grip arm and a right auxiliary arm are hinged, and the left auxiliary arm and the right auxiliary arm are hinged to the upper connecting body, respectively. Then, when the upper connecting body is raised, the sandwiching angle composed of the left grip arm and the right grip arm becomes smaller, and a part of the gripping body is locked to a part of the suspended load inserted into an insertion space.SELECTED DRAWING: Figure 1 【課題】本願発明の課題は、従来技術が抱える問題を解消することであり、すなわち新たに有孔係止具を取り付けることがなく、しかも従来技術に比して容易に吊荷を把持することができる吊治具と吊治具セット、昇降装置、さらにこの昇降装置を用いた昇降方法を提供することである。【解決手段】本願発明の吊治具は、把持体と、補助体、上部連結体を備えたものである。このうち左側把持アームの右端と右側把持アームの左端はヒンジ結合され、左側把持アームと左側補助アームがヒンジ結合されるとともに右側把持アームと右側補助アームがヒンジ結合され、左側補助アームと右側補助アームがそれぞれ上部連結体にヒンジ結合される。そして上部連結体が上昇すると、左側把持アームと右側把持アームからなる挟角が小さくなり、挿通空間に挿通された吊荷の一部に把持体の一部が係止される。【選択図】図１
