An elevator installation includes an elevator cage with a support construction carrying the elevator cage, wherein the support construction has two beams. Mounted on each beam is a positioning arrangement on which a sensor is positioned, which is part of a load measuring device, wherein the positioning arrangements have material structures. The sensors detect a change in spacing of the material structures from one another, wherein this change in spacing is caused by a change in loading of the elevator cage. Signals of the sensors are processed in an evaluating unit and a signal representing the loading is used in an elevator control.
