An elevator shuttle includes a plurality of elevator hoistways (14, 19, 24) which overlap, the elevator car frames (13, 21, 25) traveling in each hoistway including two decks per cab being carried by the car frame, plus an extra deck on car frames (20) in other than the highest (24) and lowest (14) hoistways. This allows cabs (C) traveling simultaneously, upwardly, in three or more hoistways to pass cabs (A, B) simultaneously traveling downwardly in those hoistways. The cabs may be loaded and unloaded while in the hoistway (Figs. 1, 13, 21) , or while in off-hoistway landing areas (Fig. 28). Embodiments include one cab per hoistway and two cabs per hoistway; three hoistways and four hoistways. <IMAGE> |
