Abstract
An elevator installation has a vertical elevator hoistway and a plurality of elevator cars individually movable therein. An elevator control system readies at least two of the elevator cars in the hoistway in an area of two mutually adjacent entrance areas. Thus, simultaneous loading/unloading of the elevator cars via the entrance areas is possible. The two elevator cars then travel to destination floors, the first elevator car traveling a distance which is at least as great as that traveled by the second elevator car.

A method of operating an elevator installation with a first vertical elevator hoistway and a plurality of elevator cars individually movable in the first hoistway comprising the steps of:
- a. readying at least two of the elevator cars in the first hoistway in two entrance areas of the first hoistway which are situated one immediately above the other;
- b. permitting simultaneous loading/unloading of the readied elevator cars via the entrance areas;
- and
- c. moving the readied elevator cars in the first hoistway from the entrance areas to individually assigned destination floors.
An elevator installation comprising:
- a first vertical elevator hoistway;
- a plurality of elevator cars which are individually vertically movable in said first hoistway;
- and
- an elevator control system for readying at least two of said elevator cars in the first hoistway in at least two entrance areas situated immediately above one another to enable essentially simultaneous loading/unloading of said readied elevator cars via said entrance areas, wherein after simultaneous loading/unloading said readied elevator cars are operated to travel to individually assigned destination floors.
