Abstract: An elevator system includes one or more rails fixed in a hoistway and an elevator car configured to move through the hoistway along the one or more rails. The system includes one or more braking systems having one more braking surfaces secured to the elevator car and frictionally engageable with one or more rails of the elevator system. One or more actuators are operably connected to the one or more braking surfaces configured to urge engagement and/or disengagement of the one or more braking surfaces with the rail to stop and/or hold the elevator car during operation of the elevator system.

Abstract: A device for a friction force provider for an emergency safety actuator for an elevator is disclosed. The friction force provider may include a housing having a first end and an opposing second end, where the first end may define an opening. The friction force provider may further include a primary magnet positioned within the housing and configured to move between an armed position and a working position. The primary magnet may be configured to create a force on a rail of an elevator system in the working position and be held within the housing in the armed position.

Abstract: An exemplary elevator guiderail includes a metal sheet bent into a configuration that establishes at least one mounting portion configured to facilitate mounting the guiderail within an elevator hoistway. At least one guiding portion is configured to guide movement of an elevator car along the guiderail. The metal sheet includes an exterior surface treated to resist corrosion. A cover over at least some of the guiding surface has an exterior that is different than the exterior surface of the metal sheet. The cover is configured to establish a coefficient of friction to facilitate brake engagement with the cover for resisting movement of an elevator car along the guiderail.
