As it was working to develop a new power pack, one thing quickly became clear: if HAWE were to develop a completely new hydraulic power unit, it would not only have to surpass the characteristic values of the currently available units, but would also have to be forward-looking. This is how the INKA type came…

The big highlight for Bosch Rexroth at this year’s MinExpo held in September was its new Hägglunds Atom hydraulic motor. Smaller than traditionally offered over the years, the Atom was actually developed several years ago under a different name but at a much lower pressure rating, said Brian Howell, Hägglunds Sales Manager. But the market […]

Several important trends are affecting the world of fluid power and, specifically, hydraulic power units. According to Axel Schwerdtfeger, CTO of HAWE Hydraulik, based in Munich, Germany, one important area involves digitalization and connectivity in systems. Also, electrification of mobile machines is on the rise, and thus miniaturization and decentralization of power packs — bringing…

By Josh Cosford, Contributing Editor I’ll cut to the chase; the best days for the hydraulic vane pump are likely behind us but they’re not quite ready for extinction. Let me tell you why I feel this way. Just like much of technology from the early days of the twentieth century, the vane pump came […]

This new hydraulic motor allows the fan speed to be fully variable, providing a stable machine operating temperature range allowing the material handler…

The smallest of the Hägglunds hydraulic motors from Bosch Rexroth has been transformed. The Hägglunds Atom takes over from the existing Hägglunds CAb — supplying not only more revolutions per minute, but also far more power than motors of similar size. The result is a tiny, power-dense package suitable for mobile, marine and recycling applications. […]

HAWE Hydraulik supplements the series of axial piston pumps in the medium pressure range with the new type C40V as successor model for the type V40M.

Logging and timber harvesting machinery rely on load-sensing electrohydraulics for efficient, productive operation. Contributed by Carl Dyke, LunchBox Sessions In agriculture, like any other large-scale commodity, productivity and efficiency are keys to profitability and competitiveness. In corn harvesting, for example, it is not uncommon now to find harvesters with 2,000 hp and harvesting headers wider than […]

Germany-based Frey & Co. GmbH sought technology to replace the hydraulic system in its EasyISO2000 4000-kilonewton isostatic press. The original design of the EasyISO2000 4,000-kN press included a traditional hydraulic system for five axes that Frey had used for many years. However, the solution required customers to call frequently for Frey & Co. to provide…
