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