LIEBHERR is updating its L 550 XPower and L 556 XPower wheel loaders to boost performance levels.
The manufacturer revealed it has reinforced the lift arms and overhauled the working hydraulics. Further innovations include increased tip load, breakout force and engine power.
The two models are used primarily in applications such as waste disposal.
“We remain in close contact with our customers and understand the tough conditions at landfill sites and recycling centres,” said Mark Walcher, product manager at Liebherr-Werk Bischofshofen GmbH. “With this in mind, we have purposefully invested in the performance and versatility of our two wheel loaders as part of our model updates.”
Both loaders are equipped with the power-split travel drive. By increasing the engine power, Liebherr said the travel drive is ‘even more powerful with consistently low consumption’. An increase in performance in the working hydraulics, meanwhile, has enabled ‘dynamic lift and tip functions, irrespective of the size or weight of the working tool’, the firm added. Structural modifications to the lift arms are said to have enabled higher breakout, holding and retrieval forces
For the L 550 and L 556 XPower loaders, Liebherr offers four lift arm versions in the form of z-bar kinematics and industrial kinematics both in standard and high lift configurations. The manufacturer has overhauled all four versions of the lift arms as part of the model update, as well as reinforcing the steel construction.
The tip load has increased, meaning operators can work with larger buckets and move more material in each loading process. Liebherr explained it has taken this as an opportunity to reconfigure the design of the buckets on both models, with customers able to more accurately tailor individual modules and wear parts to their needs.
The fully automatic LIKUFIX quick coupler system is being made available for the L 550 XPower and L 556 XPower machines for the first time. The system allows operators to switch mechanical and hydraulic attachments and tools from inside the cab.
