Liebherr has updated its L 550 XPower and L 556 XPower wheel loaders to deliver more engine power, improve hydraulics and increase equipment performance.
The XPower wheel loaders are used primarily in industrial operations such as in waste disposal. Paper handling, bulky metal scrap and refuse slag pose a particular challenge to a fleet of machines.
“We remain in close contact with our customers and understand the tough conditions at landfill sites and recycling centres. With this in mind, we have purposefully invested in the performance and versatility of our two wheel loaders as part of our model updates,” said Mark Walcher, product manager at Liebherr-Werk Bischofshofen GmbH.
Both the L 550 XPower and L 556 XPower wheel loaders are now equipped with a power-split travel drive, installed as standard in all Liebherr XPower wheel loaders. By increasing the engine power on both models, the travel drive is even more powerful with consistent low consumption when accelerating or penetrating into material. According to Liebherr, the loaders maintain power when equipped with heavy protective devices or solid rubber tires for industrial operations.
As well, hydraulic performance has been improved, enabling dynamic lift and tip functions, regardless of the size or weight of the tool.
Structural modifications to the lift arms deliver higher breakout, holding and retrieval forces than before. As a result, operators are now able to efficiently manipulate challenging materials such as scrap metal, paper, compost and logs, particularly in the upper lifting range.
Four lift arm version
For the L 550 and L 556 XPower wheel loaders, Liebherr offers four lift arm versions in the form of z-bar kinematics and industrial kinematics both in standard and high lift configurations.
Customers can select the version that best meets their requirements at the time of ordering. Liebherr has overhauled all four versions of the lift arms as part of the model update, as well as reinforcing the steel construction.
The modified z-bar kinematics on the XPower loaders offers 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 has also overhauled the industrial kinematics of both wheel loaders. The industrial kinematics is tailored to industrial operations that frequently require operators to work with heavy working tools such as light material buckets, high dump buckets and log grapples. Furthermore, the industrial kinematics offers parallel guidance, which is ideal for operating forklifts.

The high lift version (one for both z-bar and industrial kinematics) has extended lift arms for increased reach and more productive loading at a great height.
The overhaul of the lift arms also increases the tipping load, which means that operators of the new XPower machines can work with larger buckets than before, and move more material in each loading process.
Liebherr has taken this as an opportunity to reconfigure the design of the buckets on both models. Consequently, customers can now more accurately tailor the individual modules and wear parts of the buckets to their needs at the time of ordering.
The fully automatic LIKUFIX quick coupler system, a feature usually found on Liebherr hydraulic excavators, is being made available for the wheel loaders for the first time. The LIKUFIX quick coupler system allows operators to safely and conveniently switch mechanical and hydraulic attachments and tools from inside the cab with the press of a button.
Additional equipment allows both XPower wheel loaders to be prepared for customer-specific requirements. In addition, a hydraulic quick coupler with optimized visibility is also available, as well as a range of assistance systems, including active personnel detection at the rear with a new braking assistant, designed to increase safety in day-to-day operations.
The L550 XPower wheel loader features an operating weight of 18,550 kg, a 222 hp engine, a tipping load of 12,500 kg and a bucket capacity of 3.4 cubic metres.
The L556 XPower has an operating weight of 19,600 hp, a 13,750 kg tipping load, 249 hp engine and a 3.7 cubic metre bucket capacity.
