SUMMER 2023┃7 Kleemann | Three solutions for environmentally friendly operation. An overview of concepts and application optionsThree solutions for environmentally friendly operation. An overview of concepts and application options Kleemann uses three different drive concepts that offer the best possible solution depending on the tasks at hand. Although electric drives score very well with regard to the CO2 footprint, in some situations a fuelsaving diesel drive is the better solution. E-DRIVE, D-DRIVE and H-DRIVE represent the variants diesel-electric, diesel-direct and diesel-hydraulic. E-DRIVE – emission-free thanks to electric drive The E-DRIVE concept offers two options: Diesel fuel or all-electric. All-electric operation is environmentally friendly: there are no CO2 emissions on site. A precondition for this is a good power infrastructure, which is often available in quarries or in larger recycling yards. D-DRIVE – the direct and powerful solution The diesel-directdrive D-DRIVE provides power directly from the engine to the crusher. In the last few years, it was possible to reduce consumption, for example, through the load-dependent fan drive of the new EVO2 Generation. With regard to the degree of efficiency, the diesel-directdrive has the edge and fuel consumption is significantly lower. H-DRIVE – for mobile screening plants The screening plants from Kleemann use an effective diesel-hydraulic drive. In this case, hydraulic pumps operate all machine parts such as screen, belts and drive system. The power requirements of the screens are considerably lower than a crusher – fuel consumption during operation is therefoare more favourable. Works News E Q U I P M E N T Road Widener — Road Widener LLC, a leading global manufacturer of road construction equipment, offers the patented FH-R material placement attachment, which provides contractors with 50% reduced labor at 1/5 of the cost of traditional self-propelled equipment. Additionally, the remote-controlled design of the attachment allows the operator of the host machine to control the attachment via remote control — enhancing safety by eliminating the danger of additional workers standing along the jobsite. The FH-R is a versatile solution for material placement, precisely dispensing topsoil, gravel, asphalt, limestone and more — all with an attachment compatible with common machines that contractors already own. “With the current Bipartisan Infrastructure Deal there is a renewed focus on repairing and reconstructing our nation’s roadways,” said Lynn Marsh, Road Widener president. “Now is the time to modernize our infrastructure, making it safer and more resilient. The FH-R allows contractors to get the job done more quickly and efficiently. Our two-step process eliminates the need for grading and sweeping by placing the material right where it needs to go the first time.” The remote-controlled attachment easily connects to most skid steers, compact track loaders, road graders and wheel loaders, operating off the host machine’s engine and hydraulics. It is available in left, right or dual dispensing configurations to take on any roadway around the world. The attachment streamlines a variety of tasks including backfilling, road widening, road shoulder repairs, remediation and aggregate placement. The material is poured into the hopper at the top of the FH-R and then precisely dispensed via remote control in adjustable lay down widths from 1 to 6 feet (.3 to 1.8 meters). The attachment dispenses up to 20 tons of material in under 10 minutes.
