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.
