Reinforced lift arm for more productivity
With an annual output of 1 million tons, productivity is a top priority for the Stolz company. The wheel loaders are in operation for 250 days per year, up to 10 hours per day. On a daily basis, they more around 2,000 tons of volcanic slag (lava, basalt). Lava is light raw material with a high degree of density which stores moisture and then slowly releases it again. The reinforced Z-bar linkage of the L 580 XPower wheel loaders is the perfect choice for the volcanic bulk material of the Stolz company and offers up to 20 percent more breaking force than the previous generation.
The loading capacity is also supported by the installation location of the components. Liebherr installs heavy components, such as the engine, at the very rear. This shifts the centre of gravity towards the rear of the wheel loader, so that there is no need for additional counterweight. This ideal weight distribution results in high tipping loads and an increased handling capacity per operating hour.
A strong partnership between the two family-run companies
Just like the Liebherr company group , the Stolz company is also a family-run company and is now in its third generation since its foundation in 1953. Executive and operations management have been taken over by Dieter Stolz's sons. Rene Stolz is the director and Roman Stolz is responsible for operations management. In their own processing plants, the Stolz company produces roofing and recultivation substrates, among others. Company owner Dieter Stolz is very satisfied with quality delivered by Liebherr. "A good relationship between dealer and customer is always very important. But the high availability of the Liebherr technicians was also an important decision-making factor for me," Dieter Stolz explains.
The trust placed in the Liebherr brand clearly shows on the plant premises. Apart from the four new L 580 XPower®, there are also two L 586 wheel loaders, an L 580, an L 508 Compact, four R 974 caterpillars, two more R 934 and 936 caterpillars and a PR 734 crawler tractor in use on site.
