An illustrative example elevator assembly includes a first elevator cab and a second elevator cab. An H frame supports the first elevator cab and the second elevator cab. The H frame has a plurality of vertically oriented beams and at least one horizontally oriented beam extending between the vertically oriented beams. The at least one horizontally oriented beam is spaced from ends of the vertically oriented beams and the H frame does not have any horizontally oriented beam at either end of the vertically oriented beams. At least one linear actuator is coupled with the first elevator cab and the second elevator cab. The linear actuator is configured to selectively cause movement of the elevator cabs relative to the H frame.

A method for evacuating people with an elevator system. The method including identifying an evacuation mode in the elevator system; determining the amount of people in each building floor to be evacuated by a normal evacuation service of the elevator system and whether there exists at least one person to be evacuated who is entitled to a prioritized evacuation service; calculating an estimated evacuation waiting time for each floor to be evacuated by the normal evacuation service, wherein the calculation takes into account that the at least one person allowed to the prioritized evacuation service is evacuated first; and causing display of the estimated evacuation waiting time iii each building floor to be evacuated by the normal evacuation service.

Example embodiments relate to an elevator car, including a car spoiler at its top and/or bottom thereof, a car sling with a horizontal frame part on which at least one elevator cabin is supported, and at least one vertically extending spoiler element is located aside of the horizontal frame part. The spoiler element may have upper and lower flange portions, at least one of the upper and lower flanges being connected with elevator car parts located above and/or below of the frame part, and a vertically extending middle portion. The spoiler element may be arranged a distance from the frame part. An elevator car having this arrangement may reduce noise and provide better efficiency.

An elevator interface, communication, and control system including: a first elevator car configured to move through a first elevator shaft, the first elevator car including elevator doors configured to open and close; a first controller in electronic communication with the first elevator car; a conversion module in electronic communication with the first controller; and a first wireless access point in electronic communication with the conversion module through a hardwired connection, the first wireless access point being configured to wirelessly receive a first command from a first mobile computing device via a wireless protocol, wherein the first wireless access point is configured to transmit the first command to the conversion module, the conversion module is configured to transmit the first command to the first controller, and the first controller is configured to transmit the first command to the first elevator car.

A method of operating an elevator system includes: receiving an evacuation call from a first evacuation floor; determining an evacuation zone surrounding the first evacuation floor; determining a number of passengers on each floor within the evacuation zone; determining a set of adjacent floors within the evacuation zone that have a highest combined passenger number, the set of adjacent floors including a first adjacent floor and a second adjacent floor; and moving a multi-compartment elevator car to the set of adjacent floors with the highest combined passenger number, the multi-compartment elevator having a first compartment and a second compartment; wherein the first compartment arrives at the first adjacent floor and the second compartment arrives at the second adjacent floor when the multi-compartment elevator car arrives at the set of adjacent floors with the highest combined passenger number.

A method of installing an elevator system in a hoistway includes loading an elevator car with elevator system components for installation. The elevator car includes a first deck including one or more linear drive elements operably connected to a linear drive system at the hoistway and a second deck abutting the first deck, and separated from the first deck by a floor. The second deck is at least partially open at one side to allow access to the hoistway for installation of elevator system components in the hoistway. The elevator car is urged along the hoistway to an installation zone and the elevator system components are installed to the hoistway from the at least partially open second deck.

An adjacent safety configuration for an elevator includes a second pair of safeties displaced from a first pair of safeties by at least 0.1 seconds of travel time at a rated speed of the elevator. An adjacent safety configuration for an elevator including a second pair of safeties displaced from the first pair of safeties to provide a predetermined time period before the second pair of safeties pass over a point on a guide rail previously passed over by the first pair of safeties to permit the guide rail surface to decrease by a predetermined temperature. A method of spacing an adjacent safety configuration for an elevator system including de-rating a pair of trailing safeties with respect to a pair of leading safeties as a function of a rated speed of the elevator and a spacing between the pair of trailing safeties and the pair of leading safeties.

An elevator car includes a first floor for delimiting a transport space above it, and a second floor for delimiting a second transport space above it. One of the first and second floors is a displaceable floor, the elevator car being shiftable between a double-decker-state and a single decker-state by displacing the displaceable floor. A construction-time elevator arrangement and a method for elevator use during construction of a building, which implement the elevator car, are also disclosed.
