The manufacturer says this improvement is delivered while using about the same amount of fuel, representing a significant fuel efficiency gain. It adds that, in lighter applications, customers can expect to see up to 11% fuel savings compared to doing the same work with the previous model.
The dozer features an all-new fully automatic transmission. Added blade capacity, increased power and steering performance, and a full range of technology options are said to help customers realise more productivity and a faster payback.
The semi-universal (SU) blade capacity has been increased by 19%. At 10.3m3, the SU blade finishes jobs in fewer passes. Optional patented performance cutting edges increase blade payload by up to 25% versus standard cutting edges, especially in hard/frozen ground or heavily compacted materials.
The powertrain continuously optimises the dozer for maximum power and greatest efficiency based on the load. Caterpillar says there is no need for the operator to upshift/downshift, so operators of varying experience levels can get the most from the dozer without having to manage gear shifts.
Powered by a Cat C15 ACERT engine, the new D8T offers 264 kW/359 DIN net horsepower. Drawbar power is increased by up to 13%.
The D8T is available in standard and low ground pressure (LGP) configurations, as well as purpose-built waste and stockpile arrangements. A variety of blades and track shoe types/widths allows each machine to be optimised for performance in specific applications.
