Environmental regulations for road vehicles are becoming increasingly stringent, and one way to reduce CO2 emissions may be to eliminate mechanical V-belts or power take-offs from future commercial vehicles. Energy-efficient electrohydraulic systems, such as the latest Smart PowerPacks from Bucher Hydraulics, provide a viable alternative. Last year, the EU adopted a European Climate Law with […]

Electrohydraulic pump drive for low voltage systems
Omni Powertrain Technologies has a new electrohydraulic pump combination. The unit was developed for low voltage mobile applications and is ideally suited for the needs of hybrid equipment builders facing spatial constraints. The system includes a Flo-Torq gear pump packaged with an axial flux motor and controller from Omni’s Magelec subsidiary. The overall package length […]
Novel tunnel-boring machine takes on mining with the help of hydraulics
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 […]
Terzo introduces its more powerful Hydrapulse F3 electrohydraulic pump system
Terzo Power Systems has introduced its most powerful product to date, the Hydrapulse F3. Designed to handle the largest electrification applications in the commercial trucking, mining, and off-highway markets, the Hydrapulse Frame Size 3 (F3) offers next level power density with all the proven features and options of the Hydrapulse line. Terzo’s solutions make it […]
What is pressure compensation in a hydraulic system?
By Josh Cosford, Contributing Editor Pressure compensated pumps, pressure compensated flow controls or even just straight-up pressure compensators – these terms are thrown around constantly. But unless you’re a hydraulic specialist, you may not know what these are, let alone what they do. Of course, you’ve probably heard of systems analysts and cartographers too, but […]
Sure Grip Controls expands miniature thumb controls product line
Sure Grip Controls Inc. (Sure Grip) announces the expansion of its portfolio of miniature thumb controls. Complementing its extensive line of joysticks, handles, switches, control electronics and other components, Sure Grip has added SIL 2/PLd compatible versions of its miniature thumb controls. The new redundant configurations increase Sure Grip’s already broad range of configuration options […]
New cartridge flow transmitter revolutionizes hydraulic flow monitoring
Dale Dietel always knew there could be a better way to understand hydraulic system flows. Tired of the frustration born from the lack of easy flow monitoring, he invented his technology to provide continuous flow monitoring of all hydraulic functions — the world’s first Cartridge Flow Transmitter (CFT), from DGD Fluid Power. The CFT offers […]
How do hydraulic clutches work?
By Josh Cosford, Contributing Editor A clutch is a mechanical device that disconnects a driveshaft from its input shaft, pausing output torque. Clutches — hydraulic or otherwise — often use friction to engage the input and output ends of the assembly. The friction material is not unlike the compound employed by vehicles for their brake […]
11 tips for best use of hydraulic attachments
In our recent post, “Auxiliary hydraulics: How to match attachments and machines,” George Macintyre and Ted Polzer of CASE Construction Equipment explained the fundamentals of auxiliary hydraulics, and how to best fit machines like skid steers and CTLs with hydraulic attachments like grapples, backhoes or brooms. Here are 11 more practical tips for any user. […]
Auxiliary hydraulics: How to match attachments and machines
Skid steers and compact track loaders (CTLs) are two of the most useful pieces of mobile equipment, tackling jobs ranging from construction and landscaping to brush cutting and snow removal. Adding attachments to the machines makes them all that much more versatile. In a recent CASE LIVE presentation, “Understanding Auxiliary Hydraulics and Attachment Settings,” product […]
