    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: A sliding guide shoe for an elevator is provided including a base having a plurality of walls. A contact liner has a first side operably connected to at least one of the plurality of walls. A second side of the contact liner is configured to contact at least one surface on an elevator guide rail. The contact liner has a non-uniform thickness and is thereby configured to contact the at least one surface of the elevator guide rail over less than an entire surface of the second side of the contact liner.

    Abstract: An elevator position reference system (1) includes a hoistway (4) extending in a vertical direction and a position measurement tape (8) arranged in the hoistway (4) to extend in the vertical direction. An upper tensioning device (10) is connected to an upper end (20) of the position measurement tape (8) so as to apply a tensioning force (30) to the position measurement tape (8) in the upwards vertical direction. A lower tensioning device (12) is connected to a lower end (22) of the position measurement tape (8) so as to apply a tensioning force (32) to the position measurement tape (8) in the downwards vertical direction.

    Abstract: A locking system for an elevator car includes a moveable panel of the elevator car moveable between an open position and a closed position, wherein the open position provides access to a region external to the elevator car. Also included is a plate operatively coupled to an exterior surface of the moveable panel. Further included is a magnetic locking member operatively coupled to an exterior surface of a fixed panel of the elevator car in communication with an electrical member, wherein the plate exerts magnetic forces with the magnetic locking member, the magnetic locking member magnetically coupled to the plate in a first electrical condition of the electrical member to maintain the moveable panel in the closed position and decoupled from the plate in a second electrical condition of the electrical member to allow the moveable panel to be moved to the open position.

    Abstract: An elevator system includes a hoistway and an elevator car (12) suspended in the hoistway via one or more suspension members (46). A counterweight (22) is suspended in the hoistway via the one or more suspension members (46) to balance operation of the elevator car (12). A traction sheave (24) is located in the hoistway to drive the one or more suspension members (46) along the hoistway via traction with frictional contact between the traction sheave (24) and the one or more suspension members (46), thus driving motion of the elevator car (12) and/or counterweight (22) along the hoistway. One or more diverters (66) are positioned in the hoistway in operable contact with the one or more diverters (66). The one or more diverters (46) are configured and positioned to define a wrap angle (68) of the one or more diverters (66) about the traction sheave (24); the wrap angle (68) being between 180 degrees and 360 degrees.

    Abstract: A monitoring system for an elevator system to ensure a predetermined elevator shaft clearance is provided and includes an elevator car moveably disposed in an elevator shaft and guided along at least one guide rail, the elevator shaft having a top surface and a bottom surface. Also included is a counterweight moveably disposed in the elevator shaft. Further included is a position monitoring device monitoring a position of at least one of the elevator car and the counterweight relative to at least one of the top surface and the bottom surface. Yet further included is a braking device actuated to initiate a braking event in response to detection of the position of at least one of the elevator car and the counterweight being within a predetermined distance from one of the top surface and the bottom surface.

    Abstract: Elevator systems having a first guide rail and a second guide rail, an overtravel feature on at least one of the first or second guide rails, the overtravel feature located a first distance from a top surface of the respective guide rail, an elevator car moveable along the first and second guide rails, the elevator car including a car guidance element, and a control unit configured to perform an overtravel distance test. The control unit is configured to measure a second distance being a distance of travel of the elevator car between a landing position and a location of the overtravel feature, combine the first distance and the second distance to calculate a measured overtravel distance, and compare the measured overtravel distance with a predetermined overtravel setpoint.
