Hanson Aggregates is one of the UK’s largest producers of construction materials producing aggregates, asphalt, ready mixed concrete and cement from over 300 locations across the UK. The Padeswood cement works in North Wales and many of the concrete batching plants in the area are supplied with material won from the company’s Cefn Mawr quarry just outside Mold in Flintshire which has been operational for over 100 years. The aggregate production side of the quarry, managed by Phil Davies, has recently invested in the first Liebherr L 586 XPower® wheeled loaders in the country. Launched at bauma 2016, the XPower® range of loaders employs Liebherr’s version of the Continuously Variable Transmission (CVT) to provide a fuel efficient and durable driveline alternative to traditional mechanical driveline systems. The system combines a split driveline that is both mechanical and hydrostatic. The hydrostatic drive is most efficient in short loading cycles whilst the mechanical drive is used for long distance driving or climbing gradients. The transmission automatically manages the interaction between the two drive types and is adjustable and continually mixing the ratio of the two drives without interrupting traction. The hydrostatic portion of the drive is higher when starting the loader and during loading duties. The mechanical element is greater at higher travel speeds. The combination of CVT transmission and Liebherr Power Efficiency (LPE) software allow for potential fuel savings of 30% over comparative models. The LPE software continuously monitors the engine, transmission and hydraulic system, as well as driver input, to ensure the loader is constantly running at optimal performance. The XPower® range has also benefitted from the introduction of new Tier 4 Final emissions compliant engines with the L 586 being fitted with a six-cylinder Liebherr engine, which delivers 354 HP at a maximum of 1800 RPM with maximum torque coming at a mere 1300 RPM. Unlike many designs of wheeled loaders, the Liebherr range does away with a large counterweight instead relying on the positioning of the engine to balance the machine. This has allowed Liebherr engineers to streamline the rear canopy and allows for simple and easy access to all major components. The large and hydraulically opening bonnet also doubles up as a sturdy working INDUSTRY NEWS
