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.
