Abstract:
A braking system for an elevator system includes two or more braking surfaces located at an elevator car and frictionally engageable with a rail of an elevator system. One or more actuators are located at the elevator car and are operably connected to at least one braking surface of the two or more braking surfaces. The one or more actuators are configured to urge engagement and/or disengagement of the at least one braking surface with the rail to stop and/or hold the elevator car during operation of the elevator system. One or more braking guides are located at the elevator car to maintain a selected distance between the two or more braking surfaces and the rail.
