Abstract
The present invention relates to a mobile work machine, in particular to an excavator, that comprises an undercarriage having a tracked chassis, a rail mounting, or a wheeled chassis, a superstructure having an attachment fastened thereto, and a slewing ring that rotatably connects the undercarriage and the superstructure to one another. The work machine is characterized by a decentralized energy supply and/or by a decentralized supply network, preferably a DC supply network, and a slip ring for transferring electrical energy between the superstructure and the undercarriage.
