Tunnel construction is one of the most demanding civil engineering applications for construction equipment. Liebherr has a range of machines capable of working productively under the extreme conditions of a tunnel construction site. These include the XPower® L 550, L 556, L 566 and L 576 wheel loaders, which are now available in an optional tunnel version. The new tunnel package includes a number of features aimed specifically at optimising the robustness of these machines. This ensures high standards of safety and machine availability for tunnelling applications.
The new tunnel package for Liebherr wheel loaders includes a special soundproofed cab design that boasts a windscreen made of armoured glass. It also offers a roll over protection system (ROPS) and effectively protects machine operators from falling objects (FOPS), which is key in tunnel construction.
In the Stage IV / Tier 4f emission standards compliant XPower® wheel loaders, exhaust gas after-treatment is handled by the Liebherr SCR system. The tunnel package enhances this reliable system with the addition of a diesel particle filter, which minimises the emission of particles and contaminants in tunnels.
