Decentralized hydraulics for micro excavators
Environmental restrictions and economic pressures have spurred greater interest in hybrid and electric off-road mobile machinery. According to researchers Tatiana Minav, Matti Pietola and Shuzhong Zhang of Aalto University in Espoo, Finland, in addition to well-established methods for energy saving in hydraulic systems, a promising concept is zonal or decentralized hydraulics—an approach first pioneered in […]
Lightweight piston accumulators used in hydraulic systems for hybrid powertrains
Hydraulic energy recuperation with hydraulic accumulators responds to demands for increasingly energy efficient and fuel-conserving solutions. Developers at Freudenberg Sealing Technologies have succeeded at significantly reducing the weight of high-pressure and low-pressure piston accumulators thanks to a special construction design and a new joining technology. Hydraulic accumulators are used to store braking energy in hybrid […]

Peapod grocery delivery adds hydraulic hybrid trucks to its fleet
Peapod, an online grocer, took delivery of its first two fuel efficient, hydraulic hybrid delivery trucks this month. The vehicles, existing Workhorse walk-in vans with GM gasoline engines and equipped with the Lightning Hybrids Energy Recovery System (ERS), are in service on the streets of Chicago and were partially paid for by the Drive Clean […]
Trends in construction machinery hydraulics
Hydraulics define the evolution of construction machinery. Article updated on April 15, 2016 with new text and images. If you asked my 20-year-old self to describe the typical day on a construction site, I’d probably have described the stereotypical scene: five guys standing around watching a sixth dig a ditch. Even if there was ever any truth to that […]
Are hydraulic hybrid vehicles the future of driving?
Today, with almost every major country joining the development race, the demand for fuel is on the rise and the need to look for alternative sources of fuel looms large. One area of research taken up by auto companies has been finding practical and efficient solutions to sources of fuel for vehicles. A couple of […]
