Liebherr Presents New Generation 6 Dozer

Liebherr's new Generation 6 PR 736 dozer has an operating weight between 44,000 and 55,000 lb (20,000 and 25,000 kg). TheGeneration 6 dozer has been newly designed for increased efficiency and for reduced fuel consumption and CO2 emissions.

This model features an electronically-regulated travel drive with an integral eco-function. When the operator chooses between high-performance potential and maximum economy, the system automatically selects the optimal setting for economical operation of all travel-drive components.

Proactive power control is another Generation 6 innovation. Travel drive settings adjust automatically when the operator selects a different level of speed by the joystick, which prepares the power train for higher performance demands. In addition to fast response, this new dozer offers increased performance potential.

To simplify the use of automatic machine control systems, Liebherr supplies pre-installation kits for leading manufacturers’ systems. The automatic machine control system provides the operator with accurate guidance in order to maintain consistent grading quality.

Like all Liebherr dozers and loaders, the PR 736 features a hydrostatic transmission. This efficient driveline keeps the engine speed at a constant level of performance. Power train components and Liebherr’s intuitive engine management system match perfectly in order to achieve high efficiency and lower fuel consumption.

The new PR 736 is equipped with several features that expedite and simplify service procedures. These include centrally located maintenance points, access flaps and engine compartment doors that open to a wide angle. The machine’s tilting cab is standard, and an optional radiator that can be swung out for cleaning is available.

The new PR 736 has exceptionally long maintenance intervals for operating fluids. Depending on the nature of the work, and provided that regular quality checks are being performed, the hydraulic fluid interval can be as long as 8,000 hours of operation.

The standard Liebherr fleet management system LiDAT provides an accurate, efficient overview of essential servicing work, warning messages, the machine’s position and actual consumption data and filling levels. Depending on the customer needs, the data is updated several times a day and can be retrieved when needed by means of a web browser. An automatic alarm function can also be selected in the event of a machine leaving its predetermined zone or if a critical operating situation arises.
