To provide a lifting tool used for lifting and moving heavy objects and loads by crane, especially a lifting tool with a release function that enables the operator to easily perform a release function of the lifting tool from a remote position after lifting and moving, and to simplify the structure.SOLUTION: A lifting tool with a release function comprises a hook portion 10 on which a suspension wire 2 to hang a heavy object or load is hooked, a connection metal fitting 20 which is rotatably connected to a base portion 11 of the hook portion 10 and to which a connection wire 6 on the crane side is hooked, and a latching portion 30 that is rotatably connected to the base portion 11 of the hook portion 10, and that is engaged from above to a tip portion 12 of the hook portion 10, and functions as a latch for the suspension wire 2 hung on the hook portion 10 by closing an opening portion 13 between the base portion 11 and the tip portion 12 of the hook portion 10. On the outer surface closer to the base portion 11 of the hook portion 10, a string mooring portion 16 is provided to engage a string 40 that operates the hook portion 11 in a direction that moves the tip portion 12 of the hook portion 10 away from the latching portion 30.SELECTED DRAWING: Figure 1
【課題】クレーンによる重量物や荷の吊り上げ移動に用いる吊り具であって、特に吊り上げ移動後に、作業者が離れた位置から吊り具の開放操作を容易に行え、合わせて構造の簡素化を図ることが可能なリリース機能付き吊り具を提供する。【解決手段】重量物や荷に掛けられる吊りワイヤ2が掛止されるフック部10と、フック部10の基部11に回動可能に連結され、クレーン側の連結ワイヤ6が掛止される連結用金具20と、フック部10の基部11に回動可能に連結され、フック部10の先端部12に上方から係止され、フック部10の基部11と先端部12の間の開口部13を閉じることにより、フック部10に掛止された吊りワイヤ2の外れ止めとして機能する外れ止め部30を備え、フック部10の基部11寄りの外面に、フック部10の先端部12を外れ止め部30から離間させる方向にフック部11を回動操作する紐40を係止させる紐係止部16を設ける。【選択図】図1
