Zusammenfassung: | An elevator system includes a safety device strategically positioned within a hoistway to provide overhead or under car clearance during an inspection procedure, for example. An example safety device includes a triggering member that is selectively moved into a stopping position to engage a safety brake for preventing movement of an elevator car beyond a selected vertical position. The triggering member is selectively moveable in an automated manner between a retracted position and a stopping position. When the triggering member is in a retracted position, it has no effect on normal elevator system operation. When the triggering member 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. |
