Abstract: A hoistway access system for an elevator includes an access switch positioned at a selected landing floor 34 of an elevator and operably connected to a controller 46. A remote controlled lock 48 is located at landing doors of a landing floor providing access to a hoistway pit 36, and is operably connected to the controller. A safety actuation system is operably connected to an elevator car and operably connected to the controller. The controller is configured to command a drive system to drive the elevator car to an upper location when the access switch is activated, to define a selected safety volume in the hoistway defined by the hoistway pit and the elevator car, command engagement of the safety actuation system to stop and hold the elevator car, and command the lock to unlock when the safety actuation system is engaged, thereby allowing access to the hoistway via the landing doors.

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.

Abstract: A safety system (105) for an elevator system (100) which includes a hoistway (104), an elevator car (102) and a plurality of landing doors (112a-f). The safety system (105) includes a first safety chain (120), a second safety chain (125) and a controller (110). The first safety chain (120) is configured to produce an even landing signal and the second safety chain (125) is configured to produce an odd landing signal. The controller (110) is configured to automatically instruct the elevator system (100) to enter a special operating mode when the production of the even landing signal and the odd landing signal indicates that the elevator car (102) is located at an even landing and an odd landing door is open, or that the elevator car (102) is located at an odd landing and an even landing door is open.

Abstract: A car mounted governor (12) for an elevator system includes an overspeed pulley (38) configured to be secured to an elevator car of an elevator system. The overspeed pulley is configured to detect an overspeed condition of the elevator car via a rate at which a governor cable (42) passes around the overspeed pulley. The car mounted governor further includes a free pulley (40) configured to be secured to the elevator car with the governor cable routed over the free pulley. A tensioning device (64) is located at the free pulley and is operably connected thereto to maintain a select tension on the governor cable.
