As a direct neighbour of DK Recycling und Roheisen GmbH, HEIS processes the blast furnace slag that arises as a by-product of pig iron production. On a site covering 15,000 m², Liebherr dump trucks, material handling excavators and wheel loaders perform handling and loading operations.
Two TA 230 articulated dump trucks take cooled slag from DK and drop it in heaps. An LH 40 M material handling excavator then sieves out ferrous material using a magnetic separation system. An L 576 XPower wheel loader then loads the roughly sorted slag into a screening plant, where it is crushed and refined to different sizes.
Finally, trucks are loaded with the various grades of product before they sold as building materials and for the production of blasting abrasives. “Liebherr earthmoving machines boast excellent handling performance and low fuel consumption”, says Lars Haltermann, head of operations at HEIS.
Fuel efficient Liebherr wheel loaders ensure high customer satisfaction
What makes the XPower wheel loaders so fuel-efficient is their power-split XPower travel drive. At low speeds and short loading cycles, the hydrostatic drive does most of the work, while at higher speeds and uphill, the mechanical drive takes over. Together, the components always transmit 100 percent of the diesel engine power, with only the ratio between them changing.
This means the wheel loader operates with maximum performance and efficiency, regardless of the task. The result is fuel savings of up to 30 percent compared to conventionally driven wheel loaders. “Our XPower wheel loaders currently consume an average of 14 litres of fuel per operating hour when loading, and when feeding the screening and crushing plants”, says Haltermann.
Reliability and low maintenance
The XPower wheel loaders deliver maximum performance even on the toughest and most demanding jobs. The robust and durable components ensure a long service life for the machine. “In addition to the high quality and performance of Liebherr machines, we also appreciate the quick and easy maintenance of the XPower wheel loaders. This completes the overall package perfectly”, says Haltermann. The rear-opening electric bonnet allows safe and unhindered access to the whole engine compartment, resulting in less downtime and reduced costs.
