Method for erecting a lift installation

The invention relates to a method for centring a lift cabin in a lift installation, wherein the lift installation comprises a self-propelled lift cabin. At least two driven friction wheels are in each case pressed against each of two opposing guide surfaces of a first guide rail track and of a second guide rail track to drive the lift cabin, a first rotational speed of the friction wheels which act on the first guide rail track, and a second rotational speed of the friction wheels which act on the second guide rail track being adjustable independently of one another. The first guide rail track lies in a first plane and the second guide rail track lies in a second plane, extending substantially parallel to the first plane. A centre point of the lift cabin in a centred state is located on a central plane extending in parallel to the first and second planes. When a deviation of the centre point from the centre plane is detected, the first rotational speed and/or the second rotational speed are modified in such a manner that the centre point moves towards the centre planes upon a movement of the lift cabin along the travelway.
