An elevator car defines an interior space for accommodating passengers and/or cargo. The elevator car comprises a working platform and a tension member, wherein the working platform is moveable between a stowed position, above the interior space, and an operational position, within the interior space using the tension member. and A support member is arranged to support the working platform, from below, when the working platform is in the operational position.

An elevator system includes a hoistway; and an elevator car () disposed in and drivable along the hoistway, the elevator car including: an elevator car door (); an elevator door motor () operably connected to the elevator car door to selectably open and close the elevator car door; and a door motor brake () disposed at the elevator car door and selectably engageable with the elevator door motor to prevent operation of the elevator door motor thus preventing undesired opening and/or closure of the elevator car door.

A hoistway access system for an elevator includes an access switch positioned at a selected landing floorof an elevator and operably connected to a controller. A remote controlled lockis located at landing doors of a landing floor providing access to a hoistway pit, 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.

Elevator system hoistway access control

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.

A multi-use interface for use in an elevator includes an input device to receive input and a selection device associated with the input device, the selection device to select between an operation mode and a service mode, wherein the operation mode allows the input device to receive a standard elevator function input, the multi-use interface generating a standard elevator function output in response to the standard elevator function input, and the service mode allows the input device to receive a service function input, the multi-use interface generating a service function output in response to the service function input.

Elevator operation and service panel

A car mounted governor () for an elevator system includes an overspeed pulley () 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 () passes around the overspeed pulley. The car mounted governor further includes a free pulley () configured to be secured to the elevator car with the governor cable routed over the free pulley. A tensioning device () is located at the free pulley and is operably connected thereto to maintain a select tension on the governor cable.

A hoistway door locking system includes an elevator shaft. Also included is an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Further included is a plurality of locking mechanisms, at least one of the plurality of locking mechanisms being located at each of the plurality of access openings, wherein each of the plurality of locking mechanisms is operable between a locked condition and an unlocked condition, and wherein only a single locking mechanism may be in the unlocked condition at a specific time, the unlocked condition occurring upon alignment of the elevator car and the respective access opening having the single locking mechanism.
