Volvo Construction Equipment (Volvo CE) has won the Volvo Technology Award 2021 for its Common Pressure Rail Hybrid system for excavators.
The Volvo CE team from Sweden and South Korea has worked closely with Norrhydro in the research project, building on an idea that was born from academic collaboration.
Norrhydro’s Patented system, NorrDigi®, uses a multi-chamber digital hydraulic actuator that improves system efficiency that much of a machine’s hydraulic system can be discarded or downsized.
Currently, this innovation has evolved into a practical solution and customer trials in the field are in action. Volvo CE expects this unique electro-hydraulic solution to be available in the excavator market in a near future. The new technology will significantly improve fuel efficiency and performance while cutting down CO2 emissions. In the breakthrough system architecture, all the machines’ work functions are connected to hydraulic energy storage allowing new approaches to reduce energy losses in hydraulics.
