Abstract
An elevator installation may include at least one car that is displaceable in an elevator shaft; a first supply unit for supplying the car with energy, material, and/or data; and an interchange arrangement for interchanging the first supply unit to the car whereby the first supply unit is removed from or attached to the car during ongoing operation of the elevator installation. The interchange arrangement may be configured to remove and/or attached one or more supply units from the car during a regular door-opening cycle where the car stops at a floor of a building in which the elevator installation is installed. A duration of time required to remove the first supply unit from the car, or alternatively add the first supply unit to the car, is less than a duration of time required for a regular door-opening cycle.
