Low- and high-speed tests show that pump and motor performance can vary widely, depending on the speed and pressure. That’s critically important in electro-hydraulic actuators and electric-motor drives. Contributed by Peter Achten and Robin Mommers, Innas BV, Breda, The Netherlands Hydraulic component manufacturers generally publish pump and motor data that reflect optimal performance under ideal […]

Rugged transporter handles Antarctic extremes
An innovative design based on proven hydraulics and sophisticated controls ensured reliable and efficient performance. Prinoth Panther tracked vehicles are used on challenging worksites around the world. The rubber-tracked crawler carriers minimize damage to the underlying terrain thanks to their low ground pressure and superior stability while carrying payloads of up to 23 tons. They’re […]
Electrohydraulic actuators optimize seed depth
Designers for heavy duty motion control applications have traditionally specified hydraulic cylinders for their high speed, heavy load handling and resilience. However, recent advancements that embed hydraulic technology within electric linear actuators have been delivering the benefits of hydraulics without common drawbacks. A prime example of this conversion has been the optimization of seed depth […]
Fluid power’s green evolution
All indications are that mobile and industrial systems of the future will be more automated and more digitally connected. And many experts contend future systems will also increasingly be low-carbon and electrified. Some construction equipment OEMs, for example, are committed to autonomous control and cloud-based maintenance systems, and next-generation machines that reduce the environmental impact […]
Pioneering electrohydraulic cylinder increases equipment fuel efficiency
Volvo Construction Equipment and Finland’s Norrhydro have developed a digital hydraulic actuator that reportedly boosts productivity while radically cutting fuel bills and CO2 emissions in construction applications. If widely adopted, it could help the mobile-equipment industry meet its sustainability ambitions while at the same time revolutionize machine hydraulic performance. While the full details of the […]
Ametek releases new Gemco 959CT linear displacement transducer
Automation of machinery is a primary focus in many industries, due to three main factors: the global health situation, an economy under pressure, and improving technology. With the release of the new Gemco 959CT linear displacement transducer (LDT), Ametek Factory Automation places itself on the frontline of a wave of new automation products. Gemco’s 959CT […]
Daman now offers thermal deburring for its manifolds
Daman Products now offers thermal deburring services for standard and custom manifold projects. Thermal deburring completely removes all burr particles to ensure manifolds are 100% free of burr contamination while replacing the previous manual deburring process that is known to cause employee stress and introduce the potential for human error. One of the most prevalent […]
You can’t get something for nothing
I once had a customer call to request I visit them at their own customer’s site to help with a “breakdown.” I’m always down to help a customer, so I gladly paid a visit. Arriving on-site, many looming pieces of machinery greeted me in a heavy equipment yard. An excavator sat atop a float trailer […]
Ultra-large excavator has high-efficiency hydraulics
Hitachi Construction Machinery plans to add the EX2000-7 ultra-large hydraulic excavator to its line of mining machinery. The redesigned unit, slated for introduction next year, is based on the current EX1900-6. The model reportedly will feature an entirely new hydraulic circuit that reduces fuel consumption by up to 19% with no loss in productivity. Powered […]
High-efficiency hydraulics for electrically powered machines
Flow-on-Demand systems enable energy-saving mobile drive technology. By Dierk Peitsmeyer, Product Portfolio Manager, Bucher Hydraulics, Klettgau, Germany The Paris Agreement is the landmark environmental accord that aims to address the negative impacts of climate change and substantially reduce global greenhouse gas emissions. Although the U.S. will formally withdraw from the Agreement on Nov. 4, nearly […]
