Every type of hydraulic pump has a certain degree of delivery irregularity, causing pressure ripple in a system. Unfortunately, the fluid-borne pressure ripple can travel throughout a circuit and generate unwanted vibration and noise far from the pump. That can lead to problems ranging from excessively loud operation that is annoying to nearby workers to…

Classic hydraulic cylinders equipped with force-sensing elements allow precise and dynamic measurement of static and dynamic tensile and compressive loads. Indirect force-measurement via strain offers a smart alternative, according to engineers at Liebherr Components, Nussbaumen, Switzerland. Increasingly, mobile and industrial equipment manufacturers are focusing on sensor solutions and their efficient use in hydraulic cylinders. One […]

Offshore supply chain snarls, national-security concerns and the pandemic have all heightened the focus on domestic manufacturing capabilities. A new concept that is currently under development — metamorphic manufacturing — may usher in the capacity for local, flexible production that is especially suited for rapid and economical fabrication of small batch, complex, customized parts with…

Mobile and industrial hydraulics supplier Danfoss Power Solutions, Nordborg, Denmark, has launched its Aeroquip by Danfoss EC881 Dynamax hose. This two-wire braided hose reportedly offers higher reliability and extended service life versus similar products, reducing maintenance time, costs, and waste. EC881 hose is said to outperform standard EN 857 type 2SC hose specifications with a […]

Nearly 30 years ago, the late Bob Koski of Sun Hydraulics made a provocative presentation titled “Fluid Power Education – What went wrong?” He noted that every mechanical and electric engineer learns about electrical power actuation and motion control, but only about 5% of mechanical engineering graduates learn about fluid power actuation and control. The […]

Early in my engineering career, the fluid-power company where I was employed received a request from the U.S. Navy for seven hydraulic fittings made of the superalloy Inconel. Fulfilling the order would be a major headache. Purchasing a single bar of the exotic material, much of which would go unused, would be incredibly expensive. Add…

At last week’s 2022 Maha Fluid Power Conference at Purdue University, Chris Williamson of Danfoss presented Digital Fluid Power Systems: Challenges, Opportunities and “Critical Mass.” In his talk, he discussed some of the basics and offered his thoughts on the industry’s readiness for digital systems. Let’s start with the idea of critical mass, said Williamson.…

The 2022 Maha Fluid Power Conference was held last week at Purdue University. Katharina Schmitz, Director of the Institute for Fluid Power Drives and Systems (IFAS) at Germany’s RTWH Aachen University presented the opening keynote, “Sustainable Construction – New Challenges for Mobile Machinery.” Here are some of Dr. Schmitz’s key comments and takeaways that are…

Environmental regulations for road vehicles are becoming increasingly stringent, and one way to reduce CO2 emissions may be to eliminate mechanical V-belts or power take-offs from future commercial vehicles. Energy-efficient electrohydraulic systems, such as the latest Smart PowerPacks from Bucher Hydraulics, provide a viable alternative. Last year, the EU adopted a European Climate Law with […]

The world’s largest industrial technologies trade show returns to Hannover Messe May 30 to June 2. The Hannover Fair, considered by many to be the world’s foremost trade fair for industrial technology, will run May 30 to June 2 in Hannover, Germany. Its lead theme “Industrial Transformation” includes hydraulic and pneumatic technologies on display in…

Hydraulically powered unit is the first to cut rectangular tunnels in hard rock. Circular, full-face tunnel boring machines (TBMs) are well-engineered, proven pieces of equipment, and they’re considered the most efficient machines for mechanical excavation of tunnels in rock. But they are not often used in underground mining. That’s because mines generally require a flat […]

Mobile-equipment and controls manufacturers Ammann, Palfinger, Prinoth, Rosenbauer and TTControl, a unit of Hydac International, today announced their collaboration on application-oriented systems as part of the new Autonomous Operation Cluster (AOC). The multinational companies will jointly develop key technologies for autonomous operation elements for series production of mobile machinery functions and off-highway vehicles. The aim […]

Europe’s overreliance on imported natural gas from Russia has been a shocking wake-up call in light of Russia’s invasion of Ukraine. Last year, the European Union imported more than 400 million cubic meters per day of natural gas — almost 40% of the EU’s total gas consumption — mainly for power generation and heating. Europe…

The new directional control valve type ROLV from HAWE Hydraulik is a directional valve and shut-off valve in one. With a CETOP 3 standard connection pattern it can be integrated directly into valve banks as a flexible control block. Connection blocks for direct pipeline installation are also available. In use, the machine designer and plant…
