Piston pumps and motors have been on the market for many years, and they are arguably one of the most important components in many hydraulic circuits. The basic design behind a conventional piston pump usually has seven or nine pistons that convert mechanical torque into oil pressure. In a piston motor, the process is reversed. […]
Hydraulic hybrid cuts fuel consumption
Volvo’s new EC300E hydraulic hybrid excavator will make its debut on the North American market at ConExpo-Con/Agg 2020 in Las Vegas. Its performance is based on straightforward technology that stores hydraulic energy from machine motions in an accumulator, and then reuses it to supplement subsequent actions. The hydraulic hybrid assist system is 100% Volvo-engineered, said […]
Screw-in cartridge valves optimize hydraulics
As mobile-hydraulics engineers constantly aim to pack more capabilities into less space, custom screw-in cartridge manifolds can be an excellent option in many applications, according to officials at Cross Co., Greensboro, N.C. The products can address many needs of the machine builder, including small package size, design flexibility, and simplified plumbing and routing. And they […]
Modular pumps offer numerous control options
The LH30VO Series 20 of hydraulic pumps from Liebherr Components complements the company’s existing portfolio of hydraulic pumps in the medium pressure range. It is based on a modular system that can be adapted flexibly to customer requirements and enable various applications in mobile and stationary hydraulics. The swashplate-type axial-piston unit features a compact housing […]
Novel circuit boosts machine efficiency on Forwarder2020 project
European researchers recently wrapped up the three-year Forwarder2020 project, which aimed to develop a next-generation forwarder that’s more efficient, productive and environmentally sustainable than anything currently in use. Engineers are now reporting preliminary findings from lab tests and field trials, with encouraging results. Forwarders are articulated vehicles that carry felled timbers from the woods to […]
Hydraulic travel drive controls tire pressure
Controlling the tire pressure of crop harvesters has numerous advantages, due to different vehicle handling characteristics whether operating on roads or in fields. To address the need, Bosch Rexroth introduced the GFT 8150 TIS (Tire Inflation System), which enables dynamically optimized tire pressure in machines, at Agritechnica 2019 in Hannover, Germany. The new GFT 8150 […]
Fluid power shines with Agritechnica awards
Agritechnica, one of the world’s largest trade fairs for agricultural technology, opened this week in Hannover, Germany. According to organizer DLG (German Agricultural Society) the show is expected to attract more than 450,000 attendees from 130 countries over its seven-day run. One highlight is the announcement of this year’s Innovation Awards, a competition open to […]
Mobile IoT system harnesses machine and fleet data
Engineers at Cross Co., a supplier of fluid power components, systems and controls based in Greensboro, N.C., have developed Cross Mobile IoT. The hardware and software system connects vehicles through a sophisticated — and easy to use — cellular gateway, according to company officials, to improve fleet efficiency, reduce costs and help equipment manufacturers generate […]
Advanced hydraulics powers forest-friendly machine
Forwarder2020 project focuses on efficiency and sustainability. Forests are essential. They’re a major source of building materials and biomass for renewable energy, supply the air we breathe, prevent soil erosion and protect watersheds, promote biodiversity and offer countless recreational opportunities. And they play a critical role in CO2 capture and climate-change mitigation. For all these […]
