Abstract

Horizontally moveable elevator cabs A-E are transferrable between the car frames (72) of two elevators HI, LO in adjacent hoistways which extend between at least three levels (GND, MID, SKY) of a building, and between the car frames and landings L, R at said levels. The vertical movement of cars in the hoistways is synchronized, and transfer of elevator cabs between landings and car frames is simultaneous.
