Abstract
An illustrative example elevator assembly includes a frame having vertically oriented beams and horizontally oriented beams connected to the vertically oriented beams. A first elevator cab is supported within the frame between the vertically oriented beams. A pantograph linkage includes a plurality of links. The pantograph linkage is supported on one of the horizontally oriented beams. The pantograph linkage is connected with the first elevator cab such that different positions of the first elevator cab relative to the frame correspond to different relative positions of the links. A second elevator cab is suspended by the pantograph linkage beneath the frame. The different relative positions of the links place the second elevator cab in different positions relative to the frame.
