Rating the real performance of hydraulic pumps

January 8, 2021 By Mary Gannon

Innas engineers tested a number of hydraulic pumps and motors at both low and high speeds, with varying results. Hydraulic pump performance

Low- and high-speed tests show that pump and motor performance can vary widely, depending on the speed and pressure. That’s critically important in electro-hydraulic actuators and electric-motor drives. Contributed by Peter Achten and Robin Mommers, Innas BV, Breda, The Netherlands Hydraulic component manufacturers generally publish pump and motor data that reflect optimal performance under ideal […]

Rugged transporter handles Antarctic extremes

January 6, 2021 By Ken Korane

Prinoth’s Troll Panther vehicle carries vital supplies to remote Antarctic researchers.

An innovative design based on proven hydraulics and sophisticated controls ensured reliable and efficient performance. Prinoth Panther tracked vehicles are used on challenging worksites around the world. The rubber-tracked crawler carriers minimize damage to the underlying terrain thanks to their low ground pressure and superior stability while carrying payloads of up to 23 tons. They’re […]

Electrohydraulic actuators optimize seed depth

January 5, 2021 By Mary Gannon

The Thomson H-Track electrohydraulic linear actuator enabled Graham Electric to implement a compact, wireless electric seed depth management system that could pay for itself within the first year of operation.

Designers for heavy duty motion control applications have traditionally specified hydraulic cylinders for their high speed, heavy load handling and resilience. However, recent advancements that embed hydraulic technology within electric linear actuators have been delivering the benefits of hydraulics without common drawbacks. A prime example of this conversion has been the optimization of seed depth […]

Daman now offers thermal deburring for its manifolds

November 19, 2020 By Mary Gannon

Daman manifold thermal deburring of thread burrs

Daman Products now offers thermal deburring services for standard and custom manifold projects. Thermal deburring completely removes all burr particles to ensure manifolds are 100% free of burr contamination while replacing the previous manual deburring process that is known to cause employee stress and introduce the potential for human error. One of the most prevalent […]

You can’t get something for nothing

November 12, 2020 By Josh Cosford

A float trailer like this one was not able to lift the load required of it because of altered hydraulic pumps were not sized correctly.

I once had a customer call to request I visit them at their own customer’s site to help with a “breakdown.” I’m always down to help a customer, so I gladly paid a visit. Arriving on-site, many looming pieces of machinery greeted me in a heavy equipment yard. An excavator sat atop a float trailer […]

High-efficiency hydraulics for electrically powered machines

October 20, 2020 By Mary Gannon

Mobile machines of the future, powered by electric and hybrid drives, will demand more-efficient hydraulic components and systems. Fortunately, a number of designs that minimize losses are in the works.   

Flow-on-Demand systems enable energy-saving mobile drive technology. By Dierk Peitsmeyer, Product Portfolio Manager, Bucher Hydraulics, Klettgau, Germany The Paris Agreement is the landmark environmental accord that aims to address the negative impacts of climate change and substantially reduce global greenhouse gas emissions. Although the U.S. will formally withdraw from the Agreement on Nov. 4, nearly […]
