By Josh Cosford, Contributing Editor Hydraulic pumps convert mechanical energy into hydraulic energy, and it goes without saying every hydraulic system requires such a device to transmit controlled force to the actuators of your hydraulic machine. How you select a pump comes down to many factors but working through this guide will help you select […]

John Deere and the autonomous future
At last week’s Consumer Electronics Show in Las Vegas, John Deere put on an impressive hybrid press conference to announce its fully autonomous tractor. This isn’t some concept machine or a test vehicle. We’ve seen plenty of those over the years from OEMs; this is one that’s ready for large-scale production. The machine combines Deere’s […]
Doosan Bobcat unveils world’s first all-electric compact loader
Doosan Bobcat has introduced its new, all-electric Bobcat T7X compact track loader at the CES 2022 show in Las Vegas. The T7X is said to be the first machine of its kind to be fully electric and, according to company officials, offers the benefits of eliminating hydraulic systems, emissions and vibrations while providing cleaner, quieter […]
Why hydraulic efficiency is becoming critical
Given the heightened attention on climate change and growing regulatory attempts to rein in CO2 emissions, the push toward electrification of mobile equipment is gaining momentum. Mobile OEMs are in the infancy of a major transformation toward electric-powered systems, but success in large part hinges on more-efficient fluid power systems. Why does hydraulic efficiency matter? […]
Taking hydraulic troubleshooting one step at a time
Contributed by Steve Skinner, on behalf of Webtec LLC It’s probably fair to say that modern machinery is less prone to unexpected breakdowns than its counterparts of 30 or 40 years ago. This is due mainly to an increased emphasis on reliability engineering together with the availability of low-cost sensors, monitoring devices and digital communications. […]
How do directional seated valves operate?
In the most traditional sense, a directional control valve simply dictates the direction of hydraulic flow in some regard. The inline check valve is generally regarded as the most basic version of a directional valve, and simply allows flow in one direction while blocking flow in the opposing direction. Their advantage lies in their simple, […]
Versatile machines thanks to electronic pump controls
Manufacturers of mobile machines must decide whether to control their pumps using pressure, torque or swivel angle — and always have to accept compromises as a result. The same applies to numerous other hardware parameters which, once defined, stay the same throughout a machine’s service life. According to Simon Dreher, an excavator industry specialist with […]
How are ball valves used to ensure hydraulic safety?
By Josh Cosford, Contributing Editor In fluid power, safety is always a concern. Everyone understands the force capacity of hydraulic actuators (which explains why some YouTube hydraulic press channels have millions of subscribers). Indeed, a high-powered hydraulic press can make nearly any material appear no stronger than modelling clay. It’s wise to respect the power […]
Danfoss bullish about its merger with Eaton, sees the future as exciting
As it came up on the three-month mark for its acquisition of Eaton Hydraulics, I spoke with Eric Alström, president of Danfoss Power Solutions, about how the merger is going between the two companies and what the future holds. The conversation was positive, echoing the continued growth of the company that was highlighted over the […]
Swing-axle cylinders combine travel comfort with rigid work platform
Mobile machines have to meet widely differing requirements. To get to a job site, they need good off-road capability. While they are working, however, high rigidity and stability are essential. Add to that are increasingly demanding safety and environmental regulations. Swing-axle cylinders are built to fulfill all these requirements. According to engineers at Bucher Hydraulics, […]
