RBS Kiesgewinnung GmbH & Co. KG’s sand and gravel plant in Hamburg operates under wet conditions. A suction dredge extracts the sand and gravel mixture from the lake and wheel loaders then transport it to heaps for interim storage. This task will now be taken over by the new L 566 XPower®. During these activities, each Liebherr wheel loader deployed by this long-established Hamburg-based company turns over up to 3000 tonnes of sand and gravel per day.
Pre-purchase: XPower® prototype impresses during over 5500 hours of testing
During the intense development phase of the new XPower® large wheel loaders, RBS Kiesgewinnung GmbH & Co. KG was already testing a prototype of the L 576 XPower®, which the company’s experienced owner and managing director Andreas Buhk describes as “A very efficient and reliable wheel loader”. “During more than 5500 hours of testing, we did not experience a single failure", he adds, expressing his satisfaction with the new XPower® concept. The essential main components, such as the power-split driveline and the larger axles, have proved to be particularly robust. For Andreas Buhk, the positive test phase was a deciding factor in the purchase of the three new L 566 XPower® wheel loaders. Furthermore, he appreciates the direct contact with Liebherr: “This makes it possible to have the machines adapted to meet our precise requirements and preferences", he explains.
Liebherr XPower® driveline: maximum efficiency in sand and gravel plants
At the RBS Kiesgewinnung GmbH & Co. KG plant, the wheel loaders cover long driving distances. This is where the advantages of the emission Stage IV / Tier 4f compliant power-split Liebherr XPower® driveline come into effect. The power-split driveline combines a hydrostatic drive, which is ideal for short loading cycles, with a mechanical drive, which comes into its own on long routes and uphill. The combination of the two types of drive in a wheel loader ensures maximum efficiency whatever the operating requirements and offers exceptional fuel savings. “Even under the tough conditions in our sand and gravel plant, our new XPower® wheel loaders use up to 30 per cent less fuel per operating hour at full capacity than the previous model", says Andreas Buhk.
