Novel tunnel-boring machine takes on mining with the help of hydraulics

May 2, 2022 By Ken Korane

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 […]

Swing-axle cylinders combine travel comfort with rigid work platform

November 8, 2021 By Ken Korane

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, […]

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

July 6, 2021 By Mary Gannon

The Fendt Momentum planter from AGCO is the most agronomically advanced planter available worldwide and is designed to consistently place every seed at the optimum depth and spacing while minimizing compaction and eliminating pinch rows. Seeding machines like these rely on the power and precision of fluid power.

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. […]

Hydraulic cylinder repair: Metric in an Imperial world

May 27, 2021 By Mary Gannon

Imperial versus metric ruler

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?

May 13, 2021 By Mary Gannon

adobestock_333592786-piston-rod-stock cylinder repair raw material

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 […]

By Josh Cosford, Contributing Editor When well cared for, hydraulic cylinders should last decades. So long as they were designed for their application — meaning they perform within the bounds of their environment — there should be no reason for damage or wear outside of regular use. The mount, rod and raw material should have […]

What are the most common hydraulic cylinder piston rod problems?

January 26, 2021 By Mary Gannon

common hydraulic Cylinder piston rod problems

By Josh Cosford, Contributing Editor It would help if you never underestimate the importance of your cylinder rod. The rod is not just the object transmitting the force from the cylinder’s piston but also the interface between that cylinder and your machine. Before you can correctly select and then design the piston rod, you must […]
