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.

Abstract: An elevator car (12) for an elevator system (10) comprises: at least one side wall (38); at least one movable panel (60) forming at least a portion of the at least one side wall (38). The movable panel (60) is movable between a maintenance position, in which the panel allows access to components (28, 30, 32) of the elevator system (10), and an operational position, in which the movable panel (60) prevents access to said components (28, 30, 32). The at least one movable panel (60) comprises at least one handrail element (64), the handrail element (64) including a locking mechanism (54) which is configured to selectively lock the movable panel (60) in the operational position.

Abstract: An illustrative elevator system includes an elevator car, a machine including a motor that provides a motive force for moving the elevator car along a travel path and a brake that resists movement of the elevator car, and a brake controller. The brake controller is configured to determine when the elevator car is within a selected range of at least one end of the travel path. The brake controller inhibits a delay in application of the brake when the elevator car is within the selected range and permits a delay in application of the brake when the elevator car is outside of the selected range.
