Abstract: An elevator system includes a car disposed in and constructed and arranged to move along a hoistway that includes a centerline and is defined by a stationary structure. A plurality of position sensors of a position detection assembly are configured to be stationary with respect to the stationary structure and are spaced along the hoistway. The plurality of position sensors are configured to measure a magnetic field characteristic associated with the car, and thereby provide continuous car position data to the elevator system.

Abstract: An elevator component separation assurance system includes a controller, and a brake controller. The controller includes an electronic processor, a computer readable storage medium, a safety motion state estimator, and a safety assurance module. The safety motion state estimator is configured to identify velocity and position of each one of a plurality of elevator components. The safety assurance module is configured to select a separation map from a plurality of pre-pre-programmed separation maps for each one of an adjacent component pair of the plurality of elevator components for initiating a Ustop that maintains elevator component separation. The brake controller is carried by each one of the plurality of elevator components, and is configured to actuate a secondary brake upon detection of a loss of communication with at least a portion of the controller.

Abstract: An illustrative example elevator rope tensioning assembly includes a tensioning sheave configured to guide movement of a compensation rope. A tensioning mass is coupled with the tensioning sheave to provide weight urging the sheave in a tensioning direction. A rail structure guides vertical movement of the tensioning mass. A frictional damper continuously resists vertical movement of the tensioning mass.

Abstract: A safety gear alignment system for an elevator system includes an elevator shaft and an elevator car having an interior region and disposed in and moveable within the elevator shaft. Also included is an upright structure operatively coupled to the elevator car, the upright structure defining at least one aperture. Further included is a safety gear member having a brake and a frame, the frame operatively coupled to the upright structure. Yet further included is at least one access region defined by the frame of the safety gear member, the access region accessible from the interior region of the elevator car and wherein measurement between the frame and a guide rail of the elevator shaft is made for alignment of the safety gear member relative to the guide rail.

Abstract: An elevator system includes a hoistway and an elevator car positioned in the hoistway and configured to travel along the hoistway. The elevator car includes an elevator car door. A door operator assembly is fixed in the hoistway at a landing floor and includes a sensor to sense presence of the elevator car at the landing floor; and a door operator mechanism to open both the elevator car door and a landing floor door when the sensor senses presence of the elevator car at the landing floor. A light source may be fixed at the hoistway and a light transmitter is positioned at the elevator car to gather light from the light source and output the light into an interior of the elevator car. A ventilation system may be fixed at the hoistway and is interactive with the elevator car to condition an interior of the elevator car.

Abstract: A system and method for monitoring a first wire rope and a second wire rope is provided. The first and second wire ropes each include a contact portion that contacts a sheave, a first end portion, and a monitored portion that extends between the contact portion and the first end portion. The sheave electrically connects the contact portions of the first and second wire ropes. The system includes a controller that is electrically connected to each of the first and second wire ropes to form a circuit with the monitored portions of the first and second wire ropes. The controller selectively applies a signal to the monitored portions of the first and second wire ropes and determines an electrical characteristic thereof. The controller uses the determined electrical characteristic to determine a condition of the first and second wire ropes.
