Danfoss targets excavators with new digital-hydraulics system

Danfoss Power Solutions claims to increase the productivity of excavators while reducing their fuel consumption by up to 15% by swapping out the machine's main hydraulic pump for a Digital Displacement pump, custom software and controller. The system - appropriately called Dextreme Swap - has been fitted to three 20-ton diesel-powered Volvo EC200 excavators in Ashcourt Group's fleet for field trials, in collaboration with U.K. Volvo dealership SMT.

“Our Dextreme Swap system is configured for installation directly into excavators without modification to the existing main control valve,” Leif Bruhn, head of Digital Displacement, Danfoss Power Solutions, told Truck & Off-Highway Engineering. “We offer a simple first step for OEMs to experience and validate the benefits Dextreme systems can bring from a control and integration standpoint.” Danfoss highlighted the Dextreme system at CONEXPO/IFPE 2023 (International Fluid Power Exposition) in Las Vegas.
