Abstract:
An elevator system includes a hoistway, the hoistway having a plurality of landing floors each landing floor having a landing floor door. One or more guide rails are located in the hoistway to guide one or more elevator system components along the hoistway. An absorber is located at a hoistway pit and is supportive of a guide rail of the one or more guide rails. The absorber is configured to absorb loads imparted to the guide rail due to vertical translation and/or compression of the hoistway. A method of supporting a guide rail of an elevator system includes locating an absorber in an elevator hoistway in operable communication with a guide rail of an elevator system. Vertically-acting loads are transmitted from the guide rail to the absorber via the absorber piston thereby increasing a fluid pressure in the housing chamber.
