Abstract
An elevator assembly (20) includes braking devices (30) for controlling movement of an elevator car (22). A braking device (30) includes an electrical actuator (62) for controlling relative movement between a carriage (42) and a base (40) that is mountable on the elevator car (22). Relative movement between the carriage (42) and the base (40) results in at least one braking member (46) following a surface (60) on the base (40) for movement between a released position and a braking position.
