An elevator system (20) includes a safety device (50) strategically positioned within a hoistway to provide overhead or under car clearance during an inspection procedure, for example. An example safety device (50) includes a triggering member (56) that is selectively moved into a stopping position to engage a safety brake (42) for preventing movement of an elevator car (24) beyond a selected vertical position. The triggering member (56) is selectively moveable in an automated manner between a retracted position and a stopping position. When the triggering member (56) is in a retracted position, it has no effect on normal elevator system operation. When the triggering member (56) is in the stopping position, it provides for maintaining adequate clearance between an elevator car assembly and another surface or structure within an elevator hoistway.
