ELEVATOR SYSTEM WITH TEMPORARY HOISTWAY STRUCTURE AND METHOD FOR USE THEREOF

摘要

An elevator system in which a temporary hoistway is formed in an open air shaft of a building under construction. The hoistway members, which in turn support the guide rails, are connected to the building members in a manner that, upon forces being exerted on the guide rails, these forces are distributed to several levels of the building. The buffer assembly for protection against downward overtravel is connected to the rails and is movable upward as construction progresses. A method of using this arrangement to provide passenger elevator service into unaligned steelwork of a building under construction is also described.
