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 […]

Pioneering electrohydraulic cylinder increases equipment fuel efficiency
Volvo Construction Equipment and Finland’s Norrhydro have developed a digital hydraulic actuator that reportedly boosts productivity while radically cutting fuel bills and CO2 emissions in construction applications. If widely adopted, it could help the mobile-equipment industry meet its sustainability ambitions while at the same time revolutionize machine hydraulic performance. While the full details of the […]
Hydraulics in mining: safe and reliable
Eliminating downtime and ensuring safety in mining — two benefits hydraulics provides consistently. By Josh Cosford, Contributing Editor More than almost any other industry appropriating fluid power, mining is where safety sits front and center from design to execution. Surface mining enjoys bragging rights to some of the most massive machines ever manufactured by humans. […]
Hydraulics keeps things moving in material handling applications
Hydraulics goes a long way to improve the function, power, controllability and safety of material handling equipment. By Josh Cosford, Contributing Editor Material handling involves the moving, transporting, lifting, and dumping of products, components or bulk ingredients, and mostly within the production and distribution of finished goods. Much of the equipment used for material handling […]
Subsea Clamping Cylinder protects valuable offshore systems against premature wear
With the innovative Subsea Clamping Cylinder for fully automatic Bend Stiffener Connectors (BSCs), Bosch Rexroth is setting new standards in term of safety, reliability and economy. The system is designed for use for up to 25 years and is impressive with its high clamping forces, powerless holding operation, and easy installation with no need for […]
Hydraulics bring reliability and strength to waste management
Hydraulic cylinders and valves are common on refuse machinery, as they bring the rugged power for controlling, lifting, filling, compacting and dumping in the many types of refuse vehicles used. By Josh Cosford, Contributing Editor Waste management is an industry considered best operating in the wings, leaving the main stage orderly and immaculate. Sure, everyone […]
“Donut” actuator takes on rotary applications
Toroidal Ram Systems Ltd., based in Auckland, New Zealand, has developed a unique toroidal-shaped rotary actuator for use in high torque, heavy duty applications. The Torlite is said to be the world’s first curved-ram hydraulic actuator capable of angular rotations of up to 120°. How it works The Torlite operates similar in principle to simple […]
Oilgear looking to the future with new rotary actuators, pump designs
Naimesh Davé is the EVP and President of Oilgear, which is now part of TH Holdings. That company is the umbrella corporation for Oilgear, Texas Hydraulics, Hydromotion, and Precise Hard Chrome. I had the chance to chat with Davé and some of his engineering team last month about the company’s evolution and plans for the […]
Electrohydraulic linear actuators optimize force density and shock resistance
Thomson Industries Inc. has introduced an electrohydraulic actuator that has the strength of hydraulic cylinders but without their complex external assemblies or extensive fluid handling requirements. Thomson Warner Linear H-Track actuators move loads of up to 4,800 lb from a compact mounting envelope. The actuators are ideal for space-constrained applications requiring high load handling and […]
A disruptive sensor for intelligent hydraulics
The Liebherr LiView is an innovative position transducer for hydraulic cylinders that uses the piston itself as a sensing element. The adoption of electronic controls into mobile equipment has led to game-changing productivity enhancements — precision excavating and grading, remote maintenance capabilities and autonomous machine operation, just to name a few. But for such systems […]
