PR 746 Litronic Liebherr PR 746 Litronic Specifications & Technical Data (2022—2026)

Improved performance with the aid of Operator Assistance Systems

Automatic Free Grade & Definition Grade blade control fitted as standard. The assistance systems help the driver to work more effectively and create clean grades quickly.

Optimum ease of use and working free of fatigue in the new cabin

The ergonomic joysticks, the new rear ripper Auto Lift function and the hanging inch pedal can be individually adjusted to suit the driver. The new 9" touch display is intuitive to use and has an impressive and significantly expanded functionality. The self-regulating automatic climate control offers a pleasant interior climate and facilitates efficient working.

Adjustment to match the individual driver through electronically controlled operating hydraulics

The response behaviour for all directions of movement of the front and rear equipment can be individually adjusted to the driver to maximise ease of use. New functions: Blade shaking and lifting of the rear ripper in the park position.

Intuitive 9-inch Touch Display

Clear overview of key machine parameters A wide range of driver-specific settings: Responsiveness of operating hydraulics Responsiveness of drive hydraulics Automatic ECO Mode. Speed reduction and engine shutdown Liebherr Operator Assistance Systems control platform: Liebherr Indicate: Real-time 3D position display Free Grade: Active fine grading support Definition Grade: Creating defined 2D surfaces

Free Grade – Blade Stabilisation

Creation of a formation level: flat surfaces, ramps, dams etc. Active blade stabilisation (longitudinal grade / cross slop) when grading Increased productivity with simultaneous time saving Improved quality with less experienced operators, less stress for professional operators Greater safety on the construction site as the driver can keep his eye on the job in hand

Electronic Pilot Control of the Operating Hydraulics

In comparison to conventional systems, electronic pilot control is less temperature dependent and enables precise operation and adaptation of the response behaviour. Electronic interface for assistance and grading functions (Free & Definition Grade) In addition, the electronic pilot controlled operating hydraulics facilitate energy efficient operation and minimise wear and tear on components.

Improved sound insulation in the cabin

Hydro-elastic bearings reduce the transfer of structure-born noise from the base machine to the cabin. The rigid connection through the pivot points to the base machine for tilting the cabin (for maintenance purposes) is decoupled for operation. Powertrain components optimised for sound and vibration absorption measures reduce disruptive frequencies for the driver.
