An elevator system includes a hoistway defined by a surrounding structure. An elevator car and counterweight are located in the hoistway, and a drive motor is located between the elevator car and a sidewall of the hoistway. The drive motor drivingly couples and suspends the elevator car and counterweight via at least one flat rope or belt.

Adjustable double-deck elevator

An elevator is provided having a car, with a ceiling defined by a width and a depth, a counterweight, a plurality of ropes, a pair of first sheaves, a pair of second sheaves, and a pair of third sheaves. The car and the counterweight are connected by a plurality of ropes extending from the car to the first sheave, and then to the second sheave, then to the third sheave, and finally to the counterweight. The sheaves are positioned inside the hoistway, outside of the projected horizontal area of the ceiling of the car and therefore not directly above the ceiling in the hoistway.
