Elevator cabs transferred horizontally between double deck elevators

摘要

Horizontally moveable elevator cabs (22, 23) are transferred from the upper deck of a first car frame (26) to the upper deck of a second car frame (27) and from the lower deck of the second car frame to the lower deck of the first car frame. Three elevator hoistways, each with a double deck car frame are controlled by computer routines. A rack and pinion horizontal motive means, for moving the cab from car frame to car frame is also briefly disclosed.
