    Abstract: An elevator car comprises one or more side walls (4a) defining an interior space for accommodating passengers and/or cargo, and a support frame positioned above the interior space. A working platform (12) is suspendably connected to the support frame and moveable between a stowed position, above the interior space, and an operational position, suspended within the interior space. The working platform (12) comprises at least one stabilizing member (14) and the at least one stabilizing member (14) comprises a first engagement portion (22). At least one side wall (4a) comprises a second engagement portion (6) such as a handrail. When the working platform (12) is in the operational position, the first engagement portion (22) is configured to engage with the second engagement portion (6) so as to stabilize the working platform (12) in the operational position.

    Abstract: An elevator system (100) includes an elevator car (102) that is configured to travel along a guide rail (104), and a braking assembly (116) coupled to the elevator car (102). The braking assembly (116) is configured to selectively operate in a disengagement mode that allows the elevator car (102) to travel along the guide rail (104), and an engagement mode that inhibits the elevator car (102) from traveling along the guide rail (104). The electronic braking assembly controller (128) is in signal communication with the braking assembly (116) and is configured to generate an electronic braking signal that activates the engagement mode of the braking assembly (116). When the engagement mode is activated, the elevator car (102) decelerates without exceeding a predetermined g-force (g) threshold regardless as to whether a load applied to the elevator car (102) changes such that the elevator car (102) is stopped at a floor landing (106).

    Abstract: An elevator position reference system and a method of monitoring building settlement using such a system. The elevator position reference system includes a hoistway extending in a vertical direction. The system also includes a first position measurement tape extending vertically along a portion of the hoistway and an upper tensioning device, connected to an upper end of the first position measurement tape so as to apply a tensioning force in the upwards vertical direction. A lower end of the first position measurement tape is fixed within the hoistway. The system also includes a second position measurement tape extend vertically along at least some of said portion of the hoistway and a lower tensioning device, connected to a lower end of the second position measurement tape so as to apply a tensioning force in the downwards vertical direction.

    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: The present disclosure relates to an elevator control system (1), comprising an elevator control device (2) for operating an elevator car (12) which is adapted to be operated within an elevator shaft (18), and an inspection control station (3) configured to communicate with the elevator control device (2) for operating at least one function of an elevator system (10) in an inspection or maintenance operation mode, and configured for attachment at a storing location (71,72) of the elevator system (10), wherein the storing location (71,72) is at the elevator car (12) or within the elevator shaft (18) or in proximity of the elevator shaft (18). The inspection control station (3) is adapted to be detachable from the storing location (71,72) and configured to operate as remote inspection control station when detached from the storing location (71,72) through wireless communication with the elevator control device (2), and is configured to be movable and operable in the inspection or maintenance operation mode from inside and outside of the elevator car (12) and within the elevator shaft (18). The disclosure also relates to an elevator system (10) comprising such elevator control system (1).
