Abstract

The present invention relates to a tower crane with a load lifting means mounted on a hoisting cable, driving devices for moving several crane elements and traversing the load lifting means, and a control device for controlling the driving devices such that the load lifting means moves along a traversing path between at least two target points. The control device has a traversing path determining module for determining a desired traversing path between the at least two target points and an automatic traversing control module for automatically traversing the load lifting means along the determined traversing path.
