Abstract

An elevator system (20) includes a counterweight (24) that has a buffer member (40) that travels with the counterweight (24). A locking member (52) secures the buffer member (40) in a first position where a first length of the buffer member (40) extends beyond an outer edge (34) of the counterweight (24). The buffer member is selectively moveable into a second, retracted position relative to the counterweight (24) to allow a greater range of motion. Placing the buffer member (40) in an extended position provides overhead clearance above an associated elevator car. Placing the buffer member (40) in a retracted position provides a full range of motion of elevator system components.
