The latest Cat D6N dozer features greater ease of operation, a 10 to 15 percent boost in fuel efficiency, and an increase of up to 10 percent in productivity compared to the previous model, according to the company. It is is powered by a Tier 4-Final Cat C7.1 ACERT engine rated at 166 net horsepower and has a number of advanced technologies as standard equipment.
Cat Grade Control Slope Assist helps operators more easily achieve the required mainfall and slope orientation of the blade by automatically maintaining pre-established blade angles for the grade. Cat Stable Blade complements the operator's blade-control input for attaining higher quality finish grades quicker and with less effort. Cat Slope Indicate displays machine cross slope and mainfall (fore/aft orientation) on the primary monitor, helping operators work more accurately on slopes with no special equipment required.
Fuel-efficiency gains result primarily from the D6N's new transmission with a lock-up clutch torque converter that selects the drive mode best suited to the application, Cat says. The transmission provides the performance of direct drive with the ease of operation of power shift.
The standard Enhanced Auto Shift system, combined with the lock-up-clutch control, allows operators to select the optimum ground speed for the load being moved, resulting in further fuel savings. In addition, an electronically controlled, variable-speed demand fan automatically adjusts its speed to conserve engine horsepower and fuel, and reduce sound levels.
