Economical
Crawler excavators from Liebherr guarantee maximum productivity. The opti-
mum interplay of hydraulics and electronics means that individual movements
and superimposed movements alike can be carried out particularly efficiently.
And, perhaps last but by no means least, the perfect harmonisation of all the
components means that energy expenditure during operation can be kept to an
absolute minimum.
Economic use around the clock
Engine The Liebherr engine delivers full power even at
low speeds. It is equipped with direct injection,
turbocharger and intercooling and has an excellent
torque characteristic with high power reserves.
Automatic idling Fuel consumption and emission levels can be
reduced thanks to this selectable feature: when the
excavator is not moving or in operation, the engine
speed is automatically reduced to idle.
Service orientated Safe, non-slip steps and ergonomically positioned
handles ensure safe access to all maintenance
parts. All necessary maintenance work can be car-
ried out quickly and cost-effectively thanks to the
clever design.
Top technology for maximum profitability
Electronic engine speed
sensing control
This regulating system causes an efficient conversion
of the engine output in hydraulic performance – which
results in better utilization of the available engine
power. The result: higher digging forces, shorter cycle
times and lower fuel consumption.
Liebherr Tool-
Management-System
A unique range of digging tools and quick coupler
modules guarantee an economical advantage for
jobs with frequent tool changes. Based on years
and years of field experience, all components of the
Liebherr Tool-Management System originate from
its own research and production.
