New gen loaders with ?X? appeal

A new generation of large wheel loaders – Liebherr’s XPower series – is now on the Australian market. 

From a technology standpoint, the XPower series has already received accolades as a potential “game changer” for the earthmoving market. The XPower was the 2016 recipient of both the prestigious European Red Dot and iF Product Design awards. Previous recipients of these awards have included Kleemann, Sandvik Construction and Volvo Construction Equipment.

{{image2-a:r-w:200}}During product development, Liebherr identified four core requirements for the new loader series: fuel efficiency, power output, robustness and comfort. These principles influenced the design, unifying functionality and aesthetics. Liebherr also sought to encourage an operator/machine interaction that facilitates efficient, safe and productive operation.

The modern ergonomic cab design provides the operator with a maximum level of comfort, enabling him/her to concentrate on accurate operation without fatigue, and increasing safety and productivity. The control lever, which is built into the operator’s seat as standard, allows precise and sensitive control of the machine. The expansive glass surfaces – and the design of the engine hood which has been optimised for viewing – provide enhanced all-round visibility. This ensures maximum safety for people, the machine and the load. The most important points for daily maintenance can be seen at a glance in the XPower’s access area. Quick and safe control saves time and money.

Liebherr’s four core principles have, according to the company, been subsequently proven in extensive tests and trials, amounting to 80,000 hours in a variety of applications. In quarrying operations, the XPower wheel loaders – comprising the L 550, L 556, L 566, L 576, L 580 and L 586 models – have demonstrated a high handling capacity. The XPower generation can use standard buckets that are between 0.2m3 and 0.5m3 larger, depending on the model. The standard bucket volume varies between 3.2m3 for the L 550 XPower and 6.5m3 for the L 586 XPower. This enables machine operators to move more material with each loading cycle. To further improve operational productivity, Liebherr has reinforced the lift arm and optimised the lever ratio. The revised Z-bar linkage results in breakout forces up to 20 per cent higher than those of previous machine generations.

Power-split drive

The XPower promises more efficiency and maximum output in all areas of the quarry pit, regardless of short and long distances or flat ground and even inclines. This is possible through the innovative power-split transmission, which combines the best of the hydrostatic and mechanical concepts.

The hydrostatic driveline is the most efficient type of drive for loading operations over short
distances. The mechanical drive is the most powerful and
efficient option for travelling over long distances and driving up gradients. It is variable and continuously adapts the mixing ratio of the two drive paths automatically.

Thanks to the power-split drive, the wheel
loader is always optimally powered to ensure maximum productivity. It offers fuel savings of up to 30 per cent, compared with conventionally driven wheel loaders. In addition, there is minimal tyre wear and hardly any brake wear. At maximum handling capacity and efficiency, this reduces operating costs significantly, further increasing profitability.

The XPower wheel loaders promise maximum
performance in the toughest, most challenging
conditions in surface mines. The XPower’s
components are designed to be extremely
rugged and low wear which ensures reliability
and a long machine life. Every loader is fitted
with stronger axles than the previous machine

In addition to the axles, Liebherr has reinforced
other core components such as the hydraulic
cylinders, and continues to develop and manufacture key components in-house or in partnership with premium manufacturers. This assures components are of a consistently high quality.

Another innovation is the SCR technology
which has been developed for diesel engines
by the Liebherr Competence Centre. SCR enables all XPower wheel loaders to meet the Euro Stage IV/Tier 4f emission regulations, achieving up to 2000 hour
service intervals between oil changes. This simple,
reliable and highly effective emission reduction
system has fewer components and auxiliary
consumables than conventional diesel particle filter systems. Diesel particle filters and exhaust
gas recycling, for example, are no longer required with SCR technology.

As SCR technology does not require filter regeneration, high exhaust gas temperatures are avoided, thereby significantly reducing the risk of fire. This improves the system’s reliability and increases machine availability.

The full XPower series was launched in Australia in July.
