In the collection of hydraulic valve components, flow control valves are any device manufactured for the purpose of modifying the rate of fluid flow in a portion of a hydraulic circuit. Flow variability occurs through the adjustment of the effective orifice size inside the valve, and this is achieved through various techniques based upon the […]
Pure.Mobile position sensor kit for utility vehicles
Heat, cold, shock, vibration, water, mud or dust – modern mobile machines must work reliably under all kinds of conditions. To ensure this, the machines need sensors that record and provide data continuously even under the harshest conditions. To acquire and send this data, sensor specialist SIKO has developed Pure.Mobile technology and brought it onto […]
Liebherr’s strategy for electric mobile machines
Among mobile-equipment manufacturers, electrification — the concept of replacing diesel engines and traditional hydraulics with electric drives and batteries — is without a doubt a hot topic. But OEMs should consider both the financial and engineering ramifications before jumping in head first, according to Thomas Schulze, Drive System Application Engineer with Liebherr Components in Biberach, […]
MHP Series inductive linear position sensor for cylinders
Alliance Sensors Group, a div of H.G. Schaevitz LLC has expanded its in-cylinder position sensor product line to include the MHP-7 series linear inductive sensors. These compact inductive linear sensors were designed to be installed into the rear endcap of hydraulic cylinders for operation at pressures up to 5000psig. Their 1-inch hex aluminum or stainless steel housing […]
Smart hydraulics integral to automated dozing
Komatsu America, Rolling Meadows, Ill., recently introduced its Proactive Dozing Control logic, a fully-integrated dozing control system that lets operators perform auto-stripping, auto-spreading and high production dozing, as well as finish grading. Available on several units, Komatsu’s Proactive Dozing Control logic is built on the company’s existing intelligent machine control. The system uses Global Navigation […]
Report: Shift toward mechanization increases demand for hydraulic gear pumps
Worldwide sales of hydraulic gear pumps are likely to surpass 55,000 thousand units by end of 2020, according to a recent research study. Rising demand from a wide-range of industries, including agriculture and construction, continues to work in the favor of hydraulic gear pump manufacturers. A report on Hydraulic Gear Pump Market by Fact.MR claims […]
How do relief valves work?
By Josh Cosford, Contributing Editor It seems like a question with an easy answer, but you’d be surprised how often people ask, “how do relief valves work?” We in the fluid power industry take our knowledge for granted, but each and every one of us was at some point ignorant of literally every hydraulic component […]
Valve technology for enhanced control
Innovative application-specific valve concepts are one of the most important requirements for boosting productivity in mobile hydraulic applications, according to the engineers at Bucher Hydraulics, Remscheid, Germany. The company’s new modular SC12 proportional directional valve system, for example, offers responsive control behavior and low operating costs with consistently high machine availability. At the same time, […]
Smart sensor enhances material handling systems closed-loop control
Mobile equipment manufacturers are always striving to get the most out of their machines without overburdening the system with costly and complex mechanics. Moreover, performance expectations are not only shaping machine needs but also safety requirements. Consequently, this has driven many engineers to design closed-loop systems featuring electronic sensors as feedback devices. For example, manufacturers […]
How do I choose a joystick controller for my mobile machine?
By Josh Cosford, Contributing Editor A joystick is a type of lever used to control multiple valves or functions with a single control. It can be tilted fore and aft, and also left and right, but is often also equipped with electric or electronic buttons, switches or proportional rollers. So how do you choose a […]
