Abstract: An exemplary elevator braking device comprises a brake housing. A plurality of rollers are supported by the brake housing. The rollers are arranged to be positioned on opposite sides of a guiderail. The rollers are selectively moveable between a first position in which the rollers are spaced apart a first distance and a second position in which the rollers are spaced apart a second, smaller distance so that the rollers engage and roll along opposite sides of the guiderail. At least one biasing member is supported by the brake housing. The biasing member is associated with at least one of the rollers and biases the associated roller toward the other roller in the second position. A plurality of braking surfaces are supported by the brake housing. At least one braking surface is associated with each of the rollers. Each braking surface engages a periphery of the associated roller that faces the side of the guiderail. Friction between the periphery of the associated roller and the braking surface provides a stopping force.

Abstract: The present disclosure relates generally to a selectively operable safety brake including a magnetic brake operably coupled to a rod and disposed adjacent to a metal component, the magnetic brake configured to move between an engaging position and a non-engaging position, said magnetic brake, when in the engaging position contemporaneously with motion of the machine, moving the rod in to thereby move the safety brake from the non-braking state into the braking state, and an electromagnetic component including a retention apparatus, the electromagnetic component configured to move the magnetic brake from the engaging position to the non-engaging position upon receipt of a resetting signal.

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.

Abstract: Magnet assemblies (700) for electromechanical assemblies of elevator systems are described. The magnet assemblies include a magnet (706) and first and second block assemblies (702; 704) arranged on opposite sides of the magnet (706). In some configurations, the block assemblies (702; 704) each include a respective friction engagement surface (714) and are formed of layers (708) of sheet metal, with a portion of the layers (708) having blade teeth that form a friction engagement surface (714) for engagement with a guide rail. In some configurations, each of the block assemblies (702; 704) are formed from powder metal sintering and include a monolithic tooth configuration configured to form a friction engagement surface (714) for engagement with a guide rail. In some configurations each of the block assemblies (702; 704) includes an abrasive coating configured to form a friction engagement surface for engagement with a guide rail.
