Decentralized energy-saving hydraulic concepts for mobile working machines

First author:
Johann Lodewyks, Lucerne University, CC Mechanical Systems, Switzerland

The high price of batteries in working machines with electric drives offer a potential for
investment in energy-saving hydraulic systems. The decentralized power network
opens up new approaches for hydraulic- and hybrid circuits. In addition, the regeneration
of energy can be used at any point of the machine. For the example of an excavator
arm drive with a double cylinder two compact hydraulic circuits are presented, which
relieve a central hydraulic system.
