Caterpillar’s newest addition to its dozer family – the D10T2 builds on the original D10T model and will replace its predecessor in the 70 tonne class.
Caterpillar says refinements in power train, automated controls and structures have been made to the original D10T to produce the newer version, resulting in higher productivity with better fuel efficiency, longer machine lifespan and better access for servicing purposes.
The new model features the latest load-sensing hydraulics technology which automatically adjusts implement hydraulic power to deliver the right levels of flow and pressure for the job at hand.
The result, Caterpillar says, is less fuel burnt and more power to move the machine ahead.
Another new feature which Caterpillar claims to improve fuel efficiency is the Enhanced AutoShift (EAS) which comes standard on all D10T2 models.
EAS improves fuel efficiency and productivity by automatically selecting the optimal gear and engine speed combination based on power train load and desired ground speed. This feature functions similarly to an automatic transmission.
Caterpillar has also built the D10T2 with larger structures such as a redesigned track roller frame for a longer machine lifespan.
The D10T2 comes with two engine options – either the U.S EPA Tier 4 Final emission standards compliant Cat C27 engine with ACERT technology or a U.S EPA Tier 2 compliant engine. Both engine configurations produce net power of 600hp in forward gears and 722hp in reverse gears.
According to Caterpillar, the D10T2 has about 20 per cent more power in reverse compared to its predecessor model.
A number of new, optional electronic systems that help lessen operators’ burden are available with the new model. These include an Autocarry system which provides automatic blade control during the carry segment of the dozing cycle by measuring ground speed and track slip with a Global Navigation Satellite System (GNSS) receiver.
Another optional feature is the Adaptive Load Select which enhances the Autocarry function by automatically adjusting blade load based on operating conditions.
An Automatic Ripper Control function, also optional, monitors speed with GNSS and automatically adjusts engine speed and ripper depth to minimise track slip.
Cat’s MineStar electronic system is now available in Terrain for Grading with Blade Control which automatically guides the blade to the desired design contours, The MineStar system enables an electronic site plan to be sent to the machine from the office in real-time, showing the operator where to cut and fill.
Caterpillar says the new machine is suited for a wide range of applications such as in mining, heavy construction and bulk materials handling.
