Abstract
The present invention relates to a mobile crane boom having a self-sufficient energy supply arranged on it for supplying hydraulic energy to at least one hydraulic load arranged on the mobile crane boom. The supply of the hydraulic load arranged on the mobile crane boom is therefore not carried out by means of a hydraulic unit arranged on the revolving superstructure of the crane, which provides the hydraulic energy to each hydraulic load via hoses, but by means of a hydraulic unit which is arranged in the upper reaches of the mobile crane boom or in the area of the linkage of any second boom section. By arranging the hydraulic unit directly on the boom, the hoses normally required for supplying the hydraulic loads can be eliminated.
