Abstract
An elevator system includes a hoistway having a plurality of hoistway doors. An elevator car and counterweight are provided in the hoistway. A drive motor is drivingly coupled to the elevator car and counterweight, and is located adjacent to either the top or bottom portion of a hoistway door so as to eliminate the need to provide a machine room above the hoistway ceiling.
