ASSEMBLING GUIDE PULLEY FOR STAGE APPARATUS

摘要

PURPOSE: A prefabricated pulley for stage setting is provided, which improves efficiency of work and portability by simplifying equipment for stage setting. CONSTITUTION: A prefabricated pulley for stage setting comprises: a plurality of block sheaves(120) in which a plurality of rotation prevention projections are perpendicularly projected in a radial direction, a plurality of insertion holes are formed between neighboring rotation prevention projections in a radial direction and which are axis-installed in a shaft; and an assembly sheave(12) in which a plurality of rotation prevention projections are perpendicularly projected from one side in a radial direction, a plurality of insertion holes are formed between neighboring rotation prevention projections in a radial direction, and a rotation prevention projection of a block sheave is inserted into the insertion hole.
