By Josh Cosford, Contributing Editor Do me a favor — stand up near a wall just out of arm’s length reach. Now raise your arm with your palm facing the wall and very slowly move toward the wall. Without yet touching the wall, tell me where the force comes from to move your body close […]

DGD Fluid Power releases next-generation CFT flow meters
DGD Fluid Power has released the next-generation of CFT flow meters. The advances are in the electronics and will give greatly improved response times, said Dale Dietel, President/CEO. Included are features that raise the operating temperature to approximately 250° F and the on-board option for field adjustability include outputs of either 0.5-4.5 V or 1-10 […]
Mobile machinery makers head to Munich for bauma 2022
Construction and mining machinery industry prepared for bauma 2022, set for October 24-30. bauma is preparing to open its doors in munich october 24–30 as the world’s leading trade fair for construction machinery, building material machines, mining machines, construction vehicles and construction equipment is expecting a very high level of participation. The event, which was […]
Sun Common cartridge valve cavities provide universal solutions across applications
Helios Technologies Inc. announced this week the newest program launch from one of its operating companies, Sun Hydraulics. Developed to offer cross compatibility solutions, Sun Common cartridge valves are reliable, universal solutions for a broad variety of hydraulic systems from highly demanding applications requiring multidirectional fluid flow to simpler, lower pressure requirements. The Sun Common […]
Avoid this one piston pump mistake
Hydraulic pumps are primarily designed to convert incoming prime mover energy into hydraulic energy, manifested as pressure and flow. The term hydrostatic refers to a state of pressure equilibrium, especially in a confined space. All traditional hydraulic applications are hydrostatic, and in most cases, if you shut down the pump, physical loads should hold fast […]
What are the different types of hydraulic valves?
By Josh Cosford, Contributing Editor Hydraulic valves, used in conjunction with actuators, help make hydraulics unique in its control of force, torque and motion. Valves govern the direction, pressure and flow of hydraulic fluid, enabling smooth, safe control of actuators. A valve’s purpose may be as simple as relieving pressure to protect your pump and […]
Sorting out auxiliary hydraulics for mobile machinery
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?
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?
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 […]
What type of flow divider is best for my application?
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 […]
