To provide a posture change jig for changing a posture in a state where an object such as an arch timbering is suspended with a simple structure.SOLUTION: This posture change jig interposed between a crane and an object to change a posture in a state where the object is suspended comprises at least: a body 10; a first wire 20 moored from at least two points of the body 10 to a hook of the crane; a sheave 30 provided in the body 10; a second wire 40 moored at one end to the hook and wound at the midway on the sheave 30; a winch 50 to which the other end of the second wire 40 is connected to be wound up; and a third wire 60 provided in the body 10 to be able to suspend the object. The posture of the object suspended by the third wire 60 can be changed through rotation of the body 10 based on winding-up of the second wire 40.SELECTED DRAWING: Figure 1

    【課題】簡易な構造で、アーチ支保工などの対象物を吊った状態のまま姿勢変更を実現するための姿勢変更治具を提供する。【解決手段】クレーンと対象物との間に介在させて、対象物を吊った状態のまま姿勢変更させるための姿勢変更治具であって、本体部10と、本体部10の少なくとも二点からクレーンのフックに係留する第1のワイヤ20と、本体部10に設けたシーブ30と、一端をフックに係留し、途上をシーブ30に巻き掛ける第2のワイヤ40と、第2のワイヤ40の他端を接続して巻き上げ可能なウインチ50と、本体部10に設けて対象物を吊り可能な第3のワイヤ60と、を少なくとも具備し、第2のワイヤ40の巻き上げによる本体部10の回転によって第3のワイヤ60で吊った対象物の姿勢を変更可能とする。【選択図】図1
