A safety brake system (40; 240) for use in a conveyance system is provided. 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) comprises a safety brake (42; 242), a linkage mechanism (56; 256) and an actuator (44; 144; 244) for the safety brake (42; 242). The a 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 comprises an array of magnetic components comprising a first magnetic component adjacent to and arranged between two second magnetic components. The first magnetic component comprises one of a permanent magnet and an electromagnet and the second magnetic components each comprise the other of a permanent magnet and a electromagnet. When the electromagnet (66; 166; 266) of the first or second magnetic components is switched from the first state to a second state, the magnetic field between the array and the first ferromagnetic component is reduced and the magnetic field between the array and the second ferromagnetic component is augmented so as to move the actuator (44; 144; 244) from the first position to a second position against the second ferromagnetic component.
