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.
