Abstract

An elevator system which utilizes a plurality of independently moving cabs in each elevator shaft. The lower cabs are connected to spatially separated counterweights in order to prevent interference between cables, pulleys and counterweights. The top cab may be connected to one or two counterweights by connection points on the roof of the cab. The cabs are mounted on tracks, to guide each cab through the elevator shaft. The system includes a motor attached to each of the cabs by lift cables to facilitate the independent movement of all cabs. Existing buildings can be retrofit for compatibility with the present invention. A system and method for controlling the motions of all cabs comprising determining and selecting an optimal cab and a best hoistway range to service passenger requests.
