Abstract: An illustrative example elevator assembly includes a first elevator cab and a second elevator cab. An H frame supports the first elevator cab and the second elevator cab. The H frame has a plurality of vertically oriented beams and at least one horizontally oriented beam extending between the vertically oriented beams. The at least one horizontally oriented beam is spaced from ends of the vertically oriented beams and the H frame does not have any horizontally oriented beam at either end of the vertically oriented beams. At least one linear actuator is coupled with the first elevator cab and the second elevator cab. The linear actuator is configured to selectively cause movement of the elevator cabs relative to the H frame.

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.
