Zusammenfassung:PROBLEM TO BE SOLVED: To obtain a hoisting jig preventing shaking movement at moving time and rotating motion at lifting time. SOLUTION: In a hoisting jig, three sheaves 20 are movably mounted in three positions separated with the sheave 20 serving as each vertex of an almost regular triangle and in a single adjacent position in a main body 10, and a rope 4 is respectively wound to these three sheaves 20. In this way, when the rope 4 is placed in a position with three support parts serving as each vertex of almost a regular triangle, a rotating motion is prevented at lifting time, and when the three support parts of the rope 4 are placed in a single adjacent position, shaking movement is prevented at moving time.
