Abstract:
An elevator system () includes an underslung car (). A plurality of load bearing members (-) are closer together behind the elevator car and spaced farther apart near a front of the elevator car (). A plurality of sheaves (-) are supported for vertical movement with the car and rotational movement relative to the car () such that the load bearing members (-) can be arranged in a 2:1 roping ratio and extend underneath the car (). A disclosed example includes sheaves (-) rotatable about sheave axes that are at oblique angles relative to corresponding edges of the elevator car ().
