Abstract

A construction machine, in particular in the form of a crane, cable excavator or similar, comprising an electronic control device for controlling and/or detecting operating parameters, in addition to at least one drive device for moving a functional element, especially a load take-up means. The functional element of the construction machine is guided in the desired direction by the exertion of manipulation forces on the functional element, or on a component fastened thereto, or the functional element is moved manually in a designated direction, this motion then being assisted by the drives of the construction machine. If the functional element is manually pressed or pulled in a designated direction and/or rotated, or if this is at least attempted, these motion attempts are detected and converted into a corresponding positioning motion of the construction machine.
