Parker launches cloud-based solution to track solar panels
Parker Hannifin has launched its new SCOUT Cloud Software and SensoNODE Gold Sensors, which provide a wireless, remote monitoring solution. By monitoring the pressure levels of the solar panel tracking system’s hydraulic loads, end users can calculate how much extra pressure is being put on the panels. That information helps them identify individual panels that […]
New hydrostatic function modules with DRC software from Bosch Rexroth
During the engineering and design configuration of hydrostatic travel drives, vehicle manufacturers have to comply with the applicable Machinery Directives as soon as they plan to market construction machinery in Europe. Bosch Rexroth assists in reducing the cost for manufacturers, as the company has already carried out risk analyses according to relevant standards for an […]
Dana Rexroth introduces new versions of R2 hydromechanical variable transmission
Dana Rexroth Transmission Systems has introduced a short-drop version of the R2 hydromechanical variable transmission (HVT), with pre-production testing by original-equipment manufacturers expected to begin by the end of this year. The short-drop version of the HVT R2 is ideal for a range of material-handling, pushback, and forestry applications. Featuring a modular configuration with a redesigned transmission case that reduces input/output […]
Fluid power drives mega dozer
The PR 776 is the world’s largest hydrostatic crawler tractor. Crawler dozers are designed for tough mining, quarry, and construction operations. And like other equipment at these sites, the machines continue to get bigger as producers demand ever-increasing productivity at lower costs. As such, Liebherr, with U.S. headquarters in Newport News, Va., recently unveiled the PR […]
