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.

Elevator rail

An elevator system, suitable both for normal operating situations and for emergency situations, includes an elevator car that can be displaced directly or indirectly within an elevator shaft, a guide means that is connected to the elevator car, a derailment protection device that is connected to the elevator car, and a guide rail that has a first subregion which works together with the guide means and is used to guide the elevator car along the guide rail, and that has a second subregion which works together with the derailment protection device. A clearance between the derailment protection device and the second subregion of the guide rail is large enough that the derailment protection device and the second subregion of the guide rail remain spaced apart from each other during the normal operating situations.
