Liebherr updated two models in its XPower large wheel loader series – the L 550 XPower and L 556 XPower – and made them available in the U.S. and Canada.

According to Liebherr, it reinforced the XPower lift arms and overhauled the working hydraulics. Innovations also include increased tip load, breakout force and engine power.

The L 550 XPower and L 556 XPower are equipped with the power-split travel drive, installed as standard in all XPower wheel loaders. By increasing the engine power on both models, Liebherr says the travel drive is even more powerful with consistently low consumption, such as when accelerating or penetrating into material.

Also, an increase in performance in the working hydraulics enabled dynamic lift and tip functions, irrespective of the size or weight of the working tool. Structural modifications to the lift arms paved the way for higher breakout, holding and retrieval forces, Liebherr adds.

Features

Liebherr offers four lift arm versions in the form of z-bar kinematics and industrial kinematics – both in standard- and high-lift configurations.

The modified z-bar kinematics on the L 550 and L 556 offer strength in the lower lifting range and higher breakout forces than before. The maximum force is produced when, for example, the bucket or attachment is working close to the ground and breaks material out of a pile. This is an important feature when picking up and loading rocks, gravel or construction debris, Liebherr says.

Additionally, the overhaul of the lift arms increased the tip load, meaning operators can work with larger buckets than before and move more material in each loading process.

Liebherr reconfigured the design of the buckets on both models, as well. Now, Liebherr says customers can more accurately tailor the individual modules and wear parts of the buckets to their needs at the time of ordering.
