摘要

The method involves erecting the upper boom segment (1b) to a determined angle opposite to the horizontal, where the lower boom segment (1a) is erected, at the same time the upper boom segment is controlled depending on the crane projection. The upper boom segment is controlled, so that the projection remains constant during the erection and lies in a certain tolerance range. An independent claim is included for a crane with a crane controller.
