Abstract: An electronic safety actuation device for braking an elevator car includes a safety brake movable between a non-braking position and a braking position, a first electronic safety actuator operably coupled to the safety brake via a first link member, and a second electronic safety actuator operably coupled to the safety brake via a second link member. Operation of the first electronic safety actuator applies a force to the first link member to move the safety brake from the non-braking position to the braking position. Operation of the second electronic safety actuator applies a force to the second link member to move the safety brake from the non-braking position to the braking position.

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: Magnet assemblies for electromechanical assemblies of elevator systems are described. The magnet assemblies include a magnet and first and second block assemblies arranged on opposite sides of the magnet. In some configurations, the block assemblies each include a respective friction engagement surface and are formed of layers of sheet metal, with a portion of the layers having blade teeth that form a friction engagement surface for engagement with a guide rail. In some configurations, each of the block assemblies are formed from powder metal sintering and include a monolithic tooth configuration configured to form a friction engagement surface for engagement with a guide rail. In some configurations each of the block assemblies includes an abrasive coating configured to form a friction engagement surface for engagement with a guide rail.
