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.

An improved hoistway access detection system including three safety chains, one for monitoring door position on the even numbered floors, one for monitoring door position on the odd numbered floors, and one for monitoring the position of the pit door, wherein an elevator car is slowly moved to the alternate floor upon detection and subsequent closure of an open pit door and any landing door.
