The new Liebherr PR 736 dozer will be introduced to the American market during this construction equipment trade show in Las Vegas (USA). The PR 736 has an operating weight between 44,000 and 55,000 lb.
This 6th generation dozer has been newly designed for increased efficiency and for reduced fuel consumption and CO2 emissions.
The track assemblies have also been redesigned. In order to extend the operating life of the track and the sprocket, the drive sprockets are now of larger diameter with more teeth in mesh. When operating in abrasive surfaces, optional track assemblies with rotary bushings are available. In addition to being 100 % exchangeable, they prolong the replacement intervals for this specific type of work.
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 6th generation 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.
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.
