Abstract: An elevator car includes a car floor; a movable ceiling, which is pivotable between a normal operating position, in which the movable ceiling extends substantially horizontally and a maintenance position, in which the movable ceiling extends into an interior space of the elevator car; a working platform movably attached to the movable ceiling. The working platform is pivotable between a storage position, in which the working platform extends basically parallel to the movable ceiling, and a working position, in which the working platform extends transversely from the movable ceiling; and at least one foldable leg attached to the working platform. The at least one foldable leg is foldable between a storage configuration, in which the at least one foldable leg extends substantially parallel to the working platform, and a working configuration, in which the at least one foldable leg extends transversely from the working platform for supporting the working platform.

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 safety system (105) for an elevator system (100). The safety system (105) includes a plurality of sensors (120) and a controller (110). Each of the plurality of sensors (120) is configured to produce an override signal when a landing door (112a) to which the sensor is connected is opened by manual override. The controller (110) is configured to instruct the elevator system (100) to automatically enter a special operating mode when the override signal is received from one of the plurality of sensors (120).
