Liebherr Crawler Loaders combine customer benefits such as performance, efficiency, reliability, comfort and security at the highest level. During tunnelling, the handling capacity of these crawler loaders is second to none. This is the result of the crawler’s unsurpassed agility, its power cycle and high degree of filling capacity of the loader buckets. Especially, where space is limited, the hydrostatic drive of the LR 614, LR 624 and LR 634 models pays off. Two independently operating drive units guarantee unlimited maneuverability for full power turns and counterrotation. The hydraulic...

Tunnel equipment for LR 624/LR 634 Engine air pre-cleaner The centrifugal force of the pre-cleaner removes dust particles before they reach the filter. Especially in dust-intensive use, e.g. in tunnels, the precleaner ensures pure air is drawn in. The system permits a longer life of the filter cartridge, helps to reduce wear and to increase the engine’s life expectancy. Reversible fan When working in an environment that is subject to excessive grime and mud, the self-cleaning feature of the reversible fan is activated. The reverse air flow will remove all particles attached to the inside of...

Front attachments Strong steel cutters and wear plates provide the necessary longer life guarantee, needed for working in tunnels. No matter if used for excavating, loading, grading or pushing, all the bucket versions provide excellent filling and penetration attributes. Standard bucket The standard bucket is the most frequently used front end attachment for crawler loaders. The shape and capacity of the bucket has been designed in a way that can be efficently used in any kind of material. Bolt-on adapters teeth and segments Create a smooth surface and increase the bucket capacity....

Rear attachments Rear bumper guards As a standard feature and in order to protect the rear of the vehicle from accidental collisions in tight spaces during tunelling. All Liebherr crawler loaders are equipped with bumper guards. At the same time, these bumper guards act as counterweight, which improves the loading capacity. 3-shank ripper The massive 3-shank ripper has extraordinary penetrating and ripping capabilities. Whilst being used in tunnelling, the rear ripper increases the versatility of the crawler loader. This makes loosening the upper ground surface layer easy and its removal...
