The Liebherr XPower L 550, L 556, L 566 and L 576 wheeled loaders are now available with an optional special tunnel package, including armoured glazing and other protection features to make them more robust underground.

In this version, the special soundproofed cab has ROPS and FOPS protection. For extra reduction of emissions the already Stage IV compliant engine is enhanced with a diesel particle filter.

When designing the tunnel package, Liebherr has made targeted improvements to machine durability to keep the machine working. A ‘pre-cleaner’ is used for preliminary cleaning of the engine’s intake air, which in tunnels is typically contaminated by dust and other particles. Steel piston rod protection prevents falling pieces of stone from damaging the tipping cylinder on the wheel loader’s lift arm. The light carriers for the driving headlights are made of steel and have a protective guard attached to them. The a/c-box is also made of metal. Tough anti-collision protection prevents damage to the engine hood and the engine compartment.

LED headlights provide lighting all around the machine and an acoustic reversing alarm alerts anyone about to be run over to get out of the way. Customers can specify the acoustic reversing alarm with an additional visual alert. A reversing camera comes as standard on all XPower wheel loaders, irrespective of whether they have the tunnel package.
