Liebherr launches XPower wheel loaders in Europe

The latest XPower large wheel loaders with emission Stage IV / Tier 4f represent a milestone in the technological history of Liebherr wheel loaders. Due to the wide range of innovations, such as the power-split driveline installed as standard, Liebherr has subjected its new wheel loader generation to much tougher, more thorough and more extensive testing than ever before. Important main components, such as the innovative XPower driveline and the larger axles, were found to be particularly durable in testing over 70 000 operating hours. The load programme in the test phases included traditional back loading as well as customer-specific special operations. Liebherr deployed the XPower test wheel loaders in various quarries, and other industries.

Unique efficiency thanks

to power-split XPower driveline

Liebherr is installing the power-split XPower driveline as standard in its large wheel loader series. This ensures power and efficiency in the new Liebherr large wheel loaders. The XPower power-split transmission performs the same function as the traditional power-split transmission but with a greater level of efficiency. It combines two types of drive: the ­hydrostatic drive, the most efficient drive in short loading cycles, and the mechanical drive for long distances and driving up gradients.

With its innovative and efficient drive concepts, Liebherr has achieved a high level of efficiency in all areas where wheel loaders are used. XPower wheel loaders reduce fuel consumption by up to 30 %.

Full power at the quarry face:

test for the L 586 XPower

An L 586 XPower, fitted with a 5.5 m³ rock bucket with Liebherr tooth system, was tested in the quarrying industry by an international cement manufacturer that used it for extraction. Other standard quarrying equipment options, such as a foldable grille for the windscreen, were included on the machine to prepare it for its work at the rock face. The challenging test operation featured routes up to 400 m and inclines up to 30 %.

The benefits of the power-split driveline really came into effect under these conditions. The combination of the hydro­static and mechanical drive ensures that the wheel loader works efficiently on all operations, even on long routes and up hills. The L 586 XPower proved this to be the case in this special quarrying task. Despite the enormous load, the test loader only used around 22 litres of diesel per operating hour.
