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 […]
Differential lock valves improve fuel efficiency and control
For decades, spool-type flow dividers have proven themselves well in the differential locks of hydraulic traction drives. In recent years, however, the demands of mobile machine operators have risen to a new level. For example, market requirements now include: • More intuitive operation. • Better vehicle control, particularly when driving under difficult conditions. • Optimization […]
Editron electric converter receives agricultural engineering distinction
Danfoss Power Solutions’ Editron EC-C1700B-420 electric converter has been named a Davidson Prize winner in the annual AE50 Awards program, highlighting its value to the agricultural machinery industry. The American Society of Agricultural and Biological Engineers and the Association of Equipment Manufacturers presented the award to Danfoss on Friday, March 1, at the Commodity Classic […]
The promise and pitfalls of electric construction machines
For the last eight years engineers at Suncar AG, Zurich, Switzerland have been developing electric construction machines, and they offered some insights at the recent Future of Electrification 2024 conference, hosted by the Zapi Group. In a presentation titled “The all-electric construction machine,” Stefan Schneider, Suncar’s managing director, discussed progress on the road to electrification […]
Raising mobile machine efficiency via advanced electrohydraulics
There is heightened interest in optimizing the performance of mobile machines with electrohydraulic solutions, in particular with the coming need to transition from conventional machines to electrified zero-emission machinery. That’s according to Dr. Steffen Mutschler, Director Sales & Product Management Electrification of Mobile Machines at Bosch Rexroth. In a presentation, Empowering Optimal Performance with Electro-Hydraulic […]
Lightweight hydraulic low-speed, high-torque motors
FluiDyne Fluid Power announced the newest addition to its motor product line: the FM4 series motor, which is now available in stock alongside the FM1, FM3, and FM50/51 models. The FM series geroter gear set and spool valve flow distribution make these hydraulic motors compact, highly efficient, and perfect for low-speed high-torque applications. Whether you’re […]
