A safety brake system (40; 140; 240; 440; 540) for use in a conveyance system is provided. The safety brake system includes a guide rail (20) and a conveyance component moveable along the guide rail. The safety brake system comprises: a safety brake (46; 146; 246; 346; 446; 546) moveable between a non-braking position where the safety brake is not in engagement with the guide rail and a braking position where the safety brake is engaged with the guide rail; a linkage mechanism (54; 54c 154; 254; 354; 454; 554); and an actuator (52; 152; 252; 352; 452; 552) for the safety brake. The actuator is configured to be mounted to the conveyance component. The actuator comprises an electromagnet (56; 156; 256; 356; 456; 556) switchable between a first state and a second state; andan actuation component (58; 158; 258; 358; 458; 558) configured to move relative to the electromagnet from a first position when the electromagnet is in the first state to a second position when the electromagnet is in the second state. The linkage mechanism is coupled between the safety brake and the actuation component such that movement of the actuation component from the first position to the second position when the electromagnet is switched from the first state to the second state is transferred to the safety brake via the linkage mechanism, thus moving the safety brake into the braking position.
