Innovation, our key to performance

Hydrostatic travel drive system

The Liebherr hydrostatic drive system distinguishes itself among dozers in its class. Its high efficiency spans the entire vehicle speed range, resulting in minimal fuel consumption and low CO₂ emissions. Unlike traditional systems, the hydrostatic drive eliminates components such as torque converters, multi-ratio transmissions, service brakes, and steering couplings.

This innovative design optimises performance while minimising environmental impact!

Advantages:

Smooth and continuous speed adjustment
Consistent power stability
Precise control and easy navigation
Quick response with simple joystick inputs
Reliabale braking system

LiReCon

The Liebherr Remote Control System will revolutionise daily work routines for Crawler Dozers. Using the Liebherr teleoperation stand and high-resolution video signal, this system opens up completely new horizons: ranging from flexible remote control to exploiting areas of operation that are difficult to access. It improves safety and increases comfort and productivity, particularly when working in hazardous environments.

Advantages:

Unrivalled operating comfort
The safest operating mode
Optimising operating times

Operator assistance systems

Liebherr's generation 8 dozers offer exceptional driving comfort and performance with advanced assistance systems.

The "Free Grade" system actively stabilises the blade for precise levelling.

"Definition Grade" enables 2D surface modelling without a rotating laser, using a reference point. Automatic blade lowering ensures easy accuracy over long distances. "AutoBladePitch" enhances performance by automating blade movements for loading, carrying, and spreading.
