Abstract: An elevator system includes a hoistway and an elevator car suspended in the hoistway via one or more suspension members. A counterweight is suspended in the hoistway via the one or more suspension members to balance operation of the elevator car. A machine is positioned at the hoistway to drive the one or more suspension members along the hoistway, driving motion of the elevator car and/or counterweight along the hoistway. A suspension member termination is supported at the machine, to secure an end of the one or more suspension members. A drive system for an elevator includes one or more elevator suspension members and a machine interactive with the one or more elevator suspension members to drive motion of an elevator car. A suspension member termination is supported at the machine to secure an end of the one or more suspension members at the machine.

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. The mechanism is moveable between a first position, in which the mechanism is not engaged with the other one of the panel and the member, and a second position, in which the mechanism is engaged with the other one of the panel and the member such that the panel is held in the closed position.

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: A landing floor door access system for an elevator system includes a door lock operably connected to a landing floor door, and a door lock controller operably connected to the door lock. The door lock controller is configured for non-contact communication with an access device such that communication between the access device and the door lock controller initiates a signal from the door lock controller to the door lock to deactivate the door lock. A method of accessing a hoistway of an elevator system, includes approaching a landing floor door of the elevator system, the landing floor door positioned at the hoistway, and initiating communication between an access device and a door lock of the landing floor door via non-contact interaction between the access device and the door lock. The door lock is deactivated via the non-contact interaction between the access device and the door lock.

Abstract: An elevator car for an elevator system includes a floor and one or more elevator car side walls. At least one elevator car side wall is configured to be linearly translatable at least partially across the floor from an operational position to a maintenance position to allow for inspection and/or maintenance of elevator system components from inside of the elevator car when the elevator car side wall is at the maintenance position. A method of operating an elevator system includes driving an elevator car along a hoistway, stopping the elevator car at a first selected location along the hoistway and linearly translating a side wall of the elevator car at least partially across a floor of the elevator car from an operational position to a maintenance position, defining a maintenance area between the side wall and the hoistway. Maintenance operations on elevator system components are performed from the maintenance area.
