Abstract
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.
