Abstract
Elevator cabs A-C move upwardly through three or more contiguous overlapping hoistways 38-40 in the upper decks of double deck car frames 41-43, and move downwardly through the hoistways in the lower decks (or vice versa). To switch between decks, the cabs are offloaded from the hoistways into auxiliary elevators 50, 51 at the terminal ends of the shuttle, and are moved to be adjacent to the other deck by the auxiliary elevator and loaded thereon for the trip in the opposite direction. A second embodiment has additional auxiliary elevators 64, 65 and additional cabs D, E so that loading and unloading of passengers do not delay movement of the cabs in the hoistways.
