Abstract: An at least partially automated method for planning installation of elevator components in an elevator shaft delimited by shaft walls includes the steps: recording the course of the shaft walls; determining positions of door openings in the shaft; establishing a target course of a guide rail depending on the positions of the openings; and establishing target positions of the elevator components automatedly depending on the established guide rail target course. Adjustable ones of the elevator components have a part fixable to the shaft wall and a part movable in an adjustment range relative to the fixable part. Target positions of the movable parts are established for the adjustable components. An automated check is carried out to determine whether, when the movable part is positioned at the target position, the adjustment range is sufficient to fix the fixable part to the shaft wall and the results are output for further processing.
