An elevator installation includes a first car and a second car, which cars are arranged on a car frame so as to be displaceable symmetrically in opposite directions. The elevator installation has an information carrier that is arranged along a region of travel of the first and second cars or of the car frame, a first sensor unit arranged on the first car, and a second sensor unit arranged on the second car. The first sensor unit and the second sensor unit are configured to read information from the information carrier, which information determines in each case an absolute position for the first car and for the second car. |
