Economy With their low fuel consumption and low service and maintenance requirement, the crawler loaders make a real contribution to your economic success: Increased economy from the reduction of costs per operating hour. Efficiency in series Low fuel consumption The load sensing working hydraulics, the highly efficient hydrostatic drive unit, and the constantly low nominal speed of the Liebherr diesel engine combine to guarantee low fuel consumption.

Reliability Liebherr crawler loaders are designed for longevity. Parts that are subjected to considerable stress are produced from high-strength materials, while critical components are well protected. The result is maximum reliability and availability. Liebherr quality Everything under one roof The machines are developed, tested and built at the Liebherr production plant in Telfs (Austria). This ensures the highest quality of the entire process and of all components from the manufacturer.
