Abstract
An elevator rail guides moving bodies of an elevator system. The moving bodies serve in particular as a car for the transport of people or goods or as a counterweight. The elevator rail has more than one guide contour including a guide contourthat interacts with a guide shoe such that in a first horizontal direction, a relative horizontal movement between the guide contour and the guide shoe is delimited at least on one side, and such that in a second horizontal direction, perpendicular to the first horizontal direction, a relative horizontal movement between guide contour and the guide shoe is delimited on both sides. The elevator rail has a hollow cross section bordered in a closed manner. The elevator rail has at least three of the guide contours that are formed on the outer surface of the elevator rail.
