Cat has developed an automatic transmission for bulldozers that leads to a fuel saving of 20% in heavy work. In lighter work and fine-grading applications, the new D6T’s 4-speed, power-shift transmission with an integral lock-up clutch saves up to 30% in fuel consumption.
The new feature also makes for easier operation, with the operator only required to set the desired ground speed, while the transmission sets the optimal gear and engine speed to match the job site conditions.
An additional gear between the first and second ranges provides a smoother shifting experience and maintains power to the ground during load changes. It also allows the machine to remain in the most efficient gear for an increased amount of time.
The new dozer is powered by an EU Stage IV-certified, Cat C9.3 Acert engine with a power rating (ISO 9249/SAE J1349) of 161kW.
A choice of grade-control technologies are also available to best equip the vehicle for the job at hand, including: slope assist that automatically maintains the blade position, without requiring additional hardware or a GPS signal; a slope indicator that helps operators to work more accurately on slopes; a stable blade function that speeds up finishing grades; plus a grade-control system that provides three-dimensional guidance for production dozing and fine-grading.
In addition to these technologies, a Cat product link telematics system integrated into the D6T provides information such as location, hours, fuel usage, idle time and diagnostic codes that can be easily accessed through the online VisionLink interface.
