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: 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 braking device is operable to aid in braking a hoisted object relative to a guide member. The braking device includes a mounting structure connected to the hoisted object, and first and second brake pads positioned on the mounting structure on opposing sides of a passageway through which the guide member extends. The first and second brake pads each include a contact surface that is operable to frictionally engage the guide member. The second brake pad engages the mounting structure in a manner that enables the second brake pad to move relative to the mounting structure between a non-braking position and a braking position. The braking device includes a brake initiator that is selectively operable to initiate movement of the second brake pad from the non-braking position toward the braking position by selectively actuating an actuatable portion of the brake initiator from a non-deployed position to a deployed position.

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.
