Dr. Alan Beaulieu of ITR Economics gave his usual entertaining and fact-filled talk at the National Fluid Power Association’s annual International Economic Outlook Conference this month. Beaulieu stressed that despite all the fervor, the economy unfolded in a predictable manner — and the economy is bigger than Washington, D.C. He pointed out that the average […]
Customization enhances pressure switch functionality
Pressure switches are often considered commodity items. But for many mission-critical or demanding applications, including high-pressure hydraulics, aerospace, pharmaceuticals and more, a switch may require a custom mechanical design or electrical features that go beyond what commercial off-the-shelf switches can offer. In fact, with a little extra engineering, users can boost a switch’s performance and, […]
Shift in Motion: An innovative propulsion system for mobile machines
Manufacturers and operators of today’s mobile equipment often want a machine that does double duty: provides high tractive effort in the working mode and high maximum velocities when operating in the transport mode. These drivetrain requirements can be met through a wide array of traditional technological concepts, ranging from simple manual transmissions (shifted at standstill) […]
Danfoss wheel loader solutions uplift machine and operator performance
Danfoss Power Solutions is now offering differentiating wheel loader solutions and subsystems, which are proven at our global Application Development Centers (ADCs). The wheel loader subsystem solutions are developed and tested under real-world conditions at our ADCs and are proven to increase productivity and uptime while lowering total cost of ownership by improving efficiency. Our […]
New-generation valve actuation
Proportional hydraulic valves are key components in mobile agricultural and construction machines, as they control motion for a wide variety of functions via cylinders and hydraulic motors. Electrohydraulic actuation is often used to control valve main-spool movement. For lower flows two solenoids can directly actuate the spool, but such arrangements result in high hysteresis and […]
Hall-effect transducers ensure correct axle width to match crop row spacing
When the planting season begins, farmers will plant different crops at different row widths, requiring the sprayers to match the row width by running wheels between the plants and not over them. In the past, changing the axle width was a time-consuming task, as users would have to jack up one wheel of a tractor/sprayer, […]
Load-holding valves ensure safety in mobile equipment
Load holding valves from Valvole America are available in a very wide range of cartridges or assembled into valve blocks. They secure the last commanded position of an actuator by preventing fluid from escaping work chambers, with “zero” leakage. They ensure low leakage when closed, with less than 5 drops/min when the valve closed with […]
What does pressure really mean?
Pressure is simply the force applied perpendicular to the surface of an object per unit area over which that force is distributed. However, there are many ways to reference and identify pressure, which is largely dependent upon the application. In many applications, there is a common misconception that all pressure measurement needs to be absolute. […]
Danfoss to acquire wireless remote control technology company
Danfoss has announced the agreement to acquire the Remote Control business, currently owned by the Spanish company Ikusi, a player in the field of telecommunication networks and wireless remote controls. The Remote Control business of Ikusi includes equipment and technologies for wireless operation and control of truck-mounted cranes, winches, off-road machines, and other applications. The […]
Building a world-class hydraulic pump
Understanding what can go wrong ensures that hydraulic pumps get built right. Every OEM says it wants quality, but the reality is that machine builders can choose from countless hydraulic components that vary widely in performance and price—from cheap, “throw-away” parts to high-quality and, more-expensive, products that are built to last. How does an engineer […]
