Abstract:
An elevator system (20) includes an underslung car (22). A plurality of load bearing members (32-38) are closer together behind the elevator car and spaced farther apart near a front of the elevator car (22). A plurality of sheaves (40-44) are supported for vertical movement with the car and rotational movement relative to the car (22) such that the load bearing members (32-38) can be arranged in a 2:1 roping ratio and extend underneath the car (22). A disclosed example includes sheaves (40-44) rotatable about sheave axes that are at oblique angles relative to corresponding edges of the elevator car (22).
