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).

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).

Abstract: An elevator car comprises a panel that is moveable between a closed position, in which the panel at least partially defines a sidewall of the elevator car, and an open position, in which an opening is provided in the sidewall to an area outside of the elevator car. A member is provided external to the sidewall and extends across at least a portion of the sidewall such that, when the panel is in the open position, the opening is spanned by the member. A mechanism is on one of the panel and the member.
