Abstract
An illustrative example elevator system includes a frame, a first elevator cab, a second elevator cab, and a plurality of sheaves associated with the first and second elevator cabs, respectively. A suspension assembly suspends the first and second elevator cabs within the frame. The suspension assembly has two ends in a fixed position relative to the frame. The suspension assembly includes a positive drive load bearing member along a first portion of a length of the suspension assembly and at least one other second load bearing member. A machine includes a drive sprocket that moves the positive drive load bearing member to cause movement of the first and second elevator cabs relative to the frame.
