How can quick couplings improve hose safety?
Hydraulic and pneumatic hose safety can be ensured by using quick-connect fittings or quick couplings that make a repeated connection and disconnection between fluid lines and the equipment they are attached to. Quick couplings are used in both hydraulic and pneumatic applications, and are designed for easy hand operation. These safety devices feature a male […]
A creative approach to mobile-hydraulic controls
Contributed by Adrian Feuz, Wandfluh AG In industrial applications, a superordinate PLC often takes on the coordination of processes and the control of individual components. With hydraulic functions, for example, position control of a hydraulic axis or pressure control of clamping or pressing actions are controlled by the PLC and corresponding electronics. In this case, […]
Fluid power and the age of digitization
Not too many years ago, one could still find a small number of IoT skeptics amongst fluid power professionals.

How is electro-hydrostatic actuation technology improving the global aviation industry?
In 2015, the UN’s Intergovernmental Panel on Climate Change predicted that, by 2050 the net carbon emission of the global aviation industry could reach as high as 15% from the existing 3.5%. In this context, many major aerospace manufacturers are pursuing the philosophy of more electric, fuel-efficient, green aircrafts. One of the many technologies which […]
Three-pump hydraulic circuit powers forest harvester
The new 8-wheel-drive 931XC (Xtreme Conditions) forestry harvester from Komatsu America, Chattanooga, Tenn., is reportedly built to deliver high performance, particularly on steep, rough or soft terrain.
