Sheave assembly for an elevator system

摘要

An elevator system includes guide rail mounted machine ( 16 ) and a sheave assembly ( 32 ) that accommodates a guide rail ( 38 ) within a hoistway. The inventive sheave assembly includes individual sheave portions ( 54 ) rotatable along a common axis. At least two of the sheave portions are spaced apart along a shaft ( 50 ) and a portion of the guide rail extends toward the axis beyond a plane formed tangent to the outside diameter of the sheave portions.
