The PR 736 crawler tractor has been designed for increased efficiency and reduced fuel consumption and CO2 emissions.

This Liebherr crawler tractor offer an operating weight of 23.4 tonnes. The front of the machine is equipped with a six-way blade with internal push frame which provides a blade capacity of 4.6 m³, and the rear of the machine is equipped with a three-shank rear ripper. The undercarriage on the LGP version that is being presented has lubricated chains that are 711 mm in width. In addition, the version on show is equipped with a set-up kit for GPS machine control.

The Generation 6 models feature an electronically regulated travel drive with an integral eco-function. The driver can choose between high performance potential and maximum economy; the system automatically selected the most favourable settings for economical operation of all travel-drive components.

Proactive power control is another innovation. When a higher level of thrust is selected at the joystick, this influences the control management of the travel drive settings actively and prepares the power train for the higher performance demand. As well as responding more rapidly, the machines offer a definite increase in performance potential. Like all Liebherr crawler tractors and loaders, the PR 736 has hydrostatic transmission. This efficient driveline keeps engine speed at an almost constant level. The power train components and Liebherr’s intelligent engine management are ideally matched together for high efficiency and low fuel consumption.

To simplify the use of automatic machine control systems, Liebherr supplies ex-factory preparation kits for leading manufacturers’ systems; these kits are also available for Generation 6 models. Automatic machine control can maintain consistent high grading quality; less time is needed for preparation or subsequently, and data are memorised automatically.
