The venerable vane pump – is it still relevant?
By Josh Cosford, Contributing Editor I’ll cut to the chase; the best days for the hydraulic vane pump are likely behind us but they’re not quite ready for extinction. Let me tell you why I feel this way. Just like much of technology from the early days of the twentieth century, the vane pump came […]
Compact excavator features advanced hydraulic controls
The R2-series E88 compact excavator from Bobcat comes with several new advanced features to provide high power and lift capacity and extra productivity. The machine has a 14% increase in over-the-side lift capacity, as compared to the previous generation. The E88 comes equipped with dual-flange track rollers, integrated counterweight, extra machine weight and added track […]
Hydraulic “Infinite” cylinder upgrades timber logistics
The Hydraulic Infinite Linear Actuator offers a new way to generate mechanical linear motion. Contributed by Magnus Landberg, Landberg Solutions AB and Magnus Sethson, Linköping University, Linköping, Sweden In the forestry industry, robust and power-dense hydraulics have long played an important role in successful and cost-effective operations. Today, there is also a trend towards larger timber […]
Precision is key in agricultural machinery
The use of GPS technology, coupled with the power and precision of hydraulics, ensures modern farming success. By Josh Cosford, Contributing Editor It’s challenging to find an industry older than agriculture. Humans have been farming for over twelve millennia based on current estimates, making agriculture easily more mature than all other industries outside of carpentry. […]
LunchBox Sessions and FPW take to YouTube Live again
Last year, Fluid Power World partnered with the experts at Lunchbox Sessions to promote special, free YouTube Live training sessions to bring accessible fluid power training to the world during lockdown. And although many people are back at work, there is always a need for quality education on hydraulic systems, so we are continuing this […]
Hydraulic cylinder repair: Metric in an Imperial world
By Josh Cosford, Contributing Editor We live in a global village where local preferences seem to matter less, and acceptance of unfamiliar ideas more widespread than ever. Thirty years ago, the idea of metric bolts, nuts, threads or other objects measured in round numbers was cringe-worthy, especially in the manufacturing space. Many found it annoying […]
What is the best raw material for hydraulic cylinder repair?
By Josh Cosford, Contributing Editor When your customer’s cylinder arrives on your dock for repair, how often do you consider raw material when you quote the overhaul? Probably very little. Most hydraulic cylinders are manufactured from a combination of 1018/1020 cold rolled steel for the “square” components such as flanges, heads and caps. Piston rods […]
Load-sensing gets it done in forestry
Logging and timber harvesting machinery rely on load-sensing electrohydraulics for efficient, productive operation. Contributed by Carl Dyke, LunchBox Sessions In agriculture, like any other large-scale commodity, productivity and efficiency are keys to profitability and competitiveness. In corn harvesting, for example, it is not uncommon now to find harvesters with 2,000 hp and harvesting headers wider than […]
When should you use rotary actuators?
Rotary actuators, in many cases, are a hybrid of linear and rotary actuators. Of course, in the fluid power realm, linear and rotary actuators are more affectionately referred to simply as cylinders and motors, respectively. A cylinder creates linear force when pressure acts up its piston’s surface area, while a motor creates rotational force when […]
