To provide a lifting tool that can be handled excellently and prevent damage to the lifting tool and an object to be conveyed.SOLUTION: There is provided a lifting tool for hoisting an object T to be conveyed with a straight hole S formed on a top surface, comprising: a lift part 2 to be lifted; a wedge shaft part 3 connected to the lift part 2 and having a diameter expanded part 23 that expands in a direction away from the lift part 2; a composite anchor part 4 having a plurality of anchor members 31 disposed around the diameter expanded part 23; and a ring member 6 for binding the plurality of anchor members 31. When the wedge shaft part 3 moves relative to a lifting direction, the diameter expanded part 23 pushes each anchor member 31 outward in a radial direction and presses a bore wall of the straight hole S with an outer peripheral surface of the composite anchor part 4.SELECTED DRAWING: Figure 2

    【課題】取り扱いが良好で、吊り具及び搬送物の破損を防ぐことができる吊り具を提供する。【解決手段】上面にストレート孔Sが形成された搬送物Tを吊り上げる吊り具であって、吊り上げられるリフト部2と、リフト部2に接続され、リフト部2から離間する方向に向けて拡径する拡径部23を備えたくさび軸部3と、拡径部23の周囲に配置された複数のアンカー部材31を有する複合アンカー部4と、複数のアンカー部材31を束ねるリング部材6と、を備え、吊り上げる方向にくさび軸部3が相対移動すると、拡径部23によって各アンカー部材31が径方向外側に押し広げられ、複合アンカー部4の外周面でストレート孔Sの孔壁を押圧することを特徴とする。【選択図】図2
