    摘要: An illustrative example embodiment of an elevator governor includes a rotatable governor mechanism, a tension sheave, and a tension frame associated with the tension sheave. The tension frame has a mass configured to bias the tension frame and the tension sheave under an influence of gravity. A damper is configured to resist vertical movement of the tension frame relative to a fixed surface in a first condition and to allow vertical movement of the tension frame relative to the fixed surface in a second, different condition.

    摘要: A safety brake system (40; 240) for use in a conveyance system. The safety brake system (40; 240) includes a guide rail (20) and a conveyance component moveable along the guide rail (20). The safety brake system (40; 240) includes a safety brake (42; 242), a linkage mechanism (56; 256) and an actuator (44; 144; 244) for the safety brake (42; 242). The safety brake (42; 242) is moveable between a non-braking position where the safety brake (42; 242) is not in engagement with the guide rail (20) and a braking position where the safety brake (42; 242) is engaged with the guide rail (20). The actuator (44; 144; 244) is configured to be mounted to the conveyance component and positioned between first and second ferromagnetic components. The actuator includes an array of magnetic components including a first magnetic component adjacent to and arranged between two second magnetic components.
