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 […]
Overcoming the roadblocks to fluid power education
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 […]
Sorting out auxiliary hydraulics for mobile machinery
Understanding the hydraulic system is critical when choosing work tools and attachments for mobile machines. George MacIntyre and Ted Polzer, Product Managers, Case Construction Equipment, Racine, Wisconsin Skid steers and compact track loaders (CTLs) are two of the most useful pieces of mobile equipment, and adding attachments makes them all that much more versatile when […]
Electrohydraulics makes commercial vehicles more eco-friendly
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 […]
Novel tunnel-boring machine takes on mining with the help of hydraulics
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 […]
Off-highway industry group partners on autonomy
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 […]
Terzo announces partnership with Continental/Hydreco
Terzo Power Systems, headquartered in El Dorado Hills, California, designs and develops electrohydraulic pump systems for on- and off-highway mobile vehicles and industrial applications. The company has entered a partnership with Continental/Hydreco, leading manufacturers of mobile hydraulics, to build steering and electrohydraulic systems for global OEMs. Continental and Hydreco are both part of Duplomatic Motions […]
11 tips for best use of hydraulic attachments
In our recent post, “Auxiliary hydraulics: How to match attachments and machines,” George Macintyre and Ted Polzer of CASE Construction Equipment explained the fundamentals of auxiliary hydraulics, and how to best fit machines like skid steers and CTLs with hydraulic attachments like grapples, backhoes or brooms. Here are 11 more practical tips for any user. […]
Auxiliary hydraulics: How to match attachments and machines
Skid steers and compact track loaders (CTLs) are two of the most useful pieces of mobile equipment, tackling jobs ranging from construction and landscaping to brush cutting and snow removal. Adding attachments to the machines makes them all that much more versatile. In a recent CASE LIVE presentation, “Understanding Auxiliary Hydraulics and Attachment Settings,” product […]
Hydraulics takes a direct hit with all-electric Bobcat loader
Up until now, mobile electrification efforts were a shot across the bow of the hydraulics industry. Doosan Bobcat just hit it broadside. At this year’s CES 2022 in Las Vegas, the company premiered a new all-electric Bobcat T7X compact track loader, said to be the first machine of its kind to be fully electric and […]
