By Josh Cosford, Contributing Editor In the realm of mobile hydraulics, we must prioritize efficiency, reliability, and precision to remain competitive against other technologies. In many cases, hydraulic advancements come from partnerships with competing technologies, and one of the most important in recent years is Controller Area Network (can) networks. CAN networks revolutionize mobile hydraulics […]

Why use OHLAs for electric mobile machines?
Hydraulic motors and pumps with outward-extending shafts can be connected to various driven components, such as pulleys and gears. Overhung loads created by these connections can exert significant radial and axial forces on the hydraulic unit’s shaft and bearings. Overhung load adapters (OHLAs) provide support for these shafts, reducing the load on the internal bearings […]
Moog commits to innovation and continuity in pump production
Moog Inc. announces that the production of radial piston pumps will continue at the Böblingen site after the closure of the Nuremberg plant at the end of 2026. As Moog announced in September 2023, the current production facility for radial piston pumps (RKP) in Nuremberg will be closed by the end of 2026. In this […]
Flowcopter’s hydraulic UAV is ready for production
Flowcopter has successfully demonstrated its heavy-lift utility uncrewed aerial vehicle (UAV), the FC100, in outdoor flight trials at the UAS Denmark Test Center at Hans Christian Andersen Airport in Odense. The FC100 was born out of the need for robust, heavy payload uncrewed platforms with greater endurance in markets traditionally requiring helicopters, such as search […]
Pistol grip remote control provides ergonomically one-handed operation
Danfoss Power Solutions today announced the launch of its IK1-G pistol grip remote control. Designed for safe, reliable, one-handed remote operation of machine functions, the robust yet compact transmitter features optimized ergonomics, intuitive operation, and high configurability. The Danfoss IK1-G remote control is specifically designed for telescopic, service, and loader cranes, as well as tow […]
Innovation awards highlight mobile hydraulics
Intermat 2024, the major construction-equipment exhibition taking place this week in France, is hosting around 1,000 manufacturers of mobile machines, tools, accessories, controls and software. One highlight of the show is the Intermat Innovation Awards, which shines the spotlight on exhibitors’ equipment, products and services that contribute to progress in the construction and materials industries. […]
Bosch Rexroth launches drive systems for hydrogen filling station compressors
At Hannover Messe this week, Bosch Rexroth announced that it has developed a scalable portfolio of servohydraulic drives for compressors in the power range between 10 and 280 kW in partnership with others from the hydrogen industry. Hydrogen produced from renewable energies plays a key role in achieving global climate targets. It is a CO2-free […]
Will AI soon predict internal cylinder leakage?
Electrohydraulic actuators are standalone, self-contained systems that perform powerful tasks without external piping. They typically include an electric servomotor driving a hydraulic pump — often an axial-piston unit. Other components include a hydraulic cylinder, tank, valving and charging circuits. Because they are fitted with their own closed fluid circuit, they require only a small amount […]
Proportional valves make crane precision possible
Cranes lift heavy loads, and precise control of the lifting process is paramount for safety and efficiency. Proportional valves fine-tune the hydraulic pressure applied to the lifting mechanism so that operators can control speed and force while lifting and lowering. In 2021, Australian crane manufacturer Franna sought to improve the performance of its MAC 25 […]
When should you use hydrostatic pumps?
The term hydrostatic refers to the fundamental concept we hold dear in fluid power, which is that confined hydraulic fluid under pressure exists in equilibrium and balance. Although hydraulic fluid does no more than hold objects stationary without the active application of force through a pumping device, the concept is entirely different than hydrodynamics, which […]
