Sorting out auxiliary hydraulics for mobile machinery

June 23, 2022 By Ken Korane

the recently introduced case tv620b ctl comes with a standard high-flow auxiliary hydraulic system.

Understanding the hydraulic system is critical when choosing work tools and attachments for mobile machines. George MacIntyre and Ted Polzer, Product Managers, Case Construction Equipment, Racine, Wisconsin Skid steers and compact track loaders (CTLs) are two of the most useful pieces of mobile equipment, and adding attachments makes them all that much more versatile when […]

How do hydraulic brakes work?

June 20, 2022 By Mary Gannon

Standard and custom hydraulic brake packages from Twiflex are designed to meet the static holding and dynamic (emergency) stopping duty requirements of many types of applications, including elevators, ship loading gantry cranes, escalators, metal mill ladle cover hoists, amusement rides, conveyors, cold steel mills, ski lifts and more.

Braking systems take advantage of the textbook offerings given by hydraulics — power, controllability and safety. Hydraulic brakes are fairly simple on the cover, requiring a hydraulic pump and a brake actuator. Vehicle braking systems may get by with only what are essentially two cylinders, one at the pump and the other at the brake. […]

Are hydrogen fuel cells the future for mobile machines?

June 17, 2022 By Mary Gannon

Adaptation of the active pre-chamber in Liebherr’s H966 and H964 engines has demonstrated that heavy-duty engines can be operated with hydrogen.

Prioritizing decarbonization is, without doubt, one that most countries agree with almost pure unanimity. Here, in the U.S., the Biden administration has a goal to eliminate carbons from the electric grid system by 2035. Globally, most countries are on similar timelines. But, looking ahead to 2050, there doesn’t seem to be a clear path forward […]

By Josh Cosford, Contributing Editor Flow dividers provide a unique solution to a specific problem in hydraulic applications — splitting flow while limiting its tendency to take the path of least resistance. Without a flow divider, any time you wish to split flow to two or more downstream subcircuits, the path with the lowest pressure […]

How Gemco is working around supply shortages for its linear position sensors

May 26, 2022 By Mary Gannon

Gemcos CT959 linear position sensor housing for hydraulic cylinder

A wide range of industries is showing significant supply chain issues. However, the Michigan-based manufacturer of Gemco linear position sensors, AMETEK Factory Automation, has proven they can still deliver in a timely manner. In the past couple of years, an increasing supply shortage due to various factors has caused manufacturing and on-time delivery issues. On […]

Electrohydraulics makes commercial vehicles more eco-friendly

May 5, 2022 By Ken Korane

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

May 4, 2022 By Mary Gannon

Omni Powertrain Electrohydraulic pump drive

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

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 […]

What is pressure compensation in a hydraulic system?

April 7, 2022 By Mary Gannon

Pressure compensated flow controls

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 […]
