Abstract
An elevator system is provided including a hoistway having a plurality of landings. An elevator car is configured to move within the hoistway between the plurality of landings. A plurality of guide rails guide movement of the elevator car and a counterweight within the hoistway. Each guide rail includes a base and a blade. A machine assembly is mounted within the hoistway and includes a traction sheave rotatable about an axis. The traction sheave is configured to drive movement of the elevator car between the plurality of landings. At least one of the plurality of guide rails is arranged in an overlapping configuration with the machine assembly such that a plane defined by the base of the guide rail is parallel to the axis and intersects a portion of the traction sheave.
