  • Patent number: 8028808
    Abstract: An assembly (30) controls the amount of downward movement of a counterweight (24) within an elevator system (20). By limiting the downward movement of the counterweight (24), a desired overhead clearance above an elevator car (22) can be maintained. One example includes at least one safety device (80, 84, 86, 88) on top of the elevator car (22) to provide an indication for when a holding member (34) should allow a stop member of the assembly (30) to move into a position to limit the downward movement of the counterweight (24). In one example, the stop member (32) moves into an employed position by the force of gravity and is manually moveable back into a retracted position when it is not needed. One example includes a guide member (60) that facilitates controlling the position of the stop member (32) when it is in the employed position.

  • Patent number: 7650969
    Abstract: 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.
