Caterpillar launches new D8T dozer designed to deliver greater productivity

Global Mining Review,

Caterpillar’s recently released D8T dozer is designed to move more material in less time, at a lower cost per tonne, for a faster return on equipment investment. The bulldozer features an all-new fully automatic transmission, delivering up to 18% more productivity without consuming more fuel, as well as unprecedented ease of operation. Added blade capacity, increased power and steering performance, and a full range of technology options help customers realise more productivity and a faster payback.

Move more material, use less fuel

The new D8T moves up to 18% more material per hour than the previous model, while using about the same amount of fuel, representing a significant fuel efficiency gain. In lighter applications, customers can also expect to see up to 11% fuel savings compared to doing the same work with the previous model.

Much of the productivity gain comes from a new Caterpillar-designed fully-automatic 4-speed transmission. The powertrain continuously optimises the dozer for maximum power and greatest efficiency based on the load. 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. The added gear and seamless lock-up clutch engagement ensure smooth shifting.

The semi-universal (SU) blade capacity has been increased by 19%. At 10.3 m3, the largest SU blade in the size class 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.

Powered by a Cat C15 ACERT™ engine, the new D8T offers class-leading 264 kW/359 DIN net horsepower. Drawbar power is increased by up to 13%. A 10% increase in steering torque, fully automatic transmission and differential steering combine to provide best-in-class steering performance under load.  

Save maintenance, time and money

Like all Cat dozers, the D8T is designed for easy routine maintenance with features such as grouped service points and a ground level service centre. New cartridge fuel filters, longer engine oil service interval and standard programmable automatic reversing fan help save maintenance time. The new optional heavy duty extended life undercarriage – Cat HDXL with DuraLink™ – offers up to 25% more wear life in abrasive conditions to help reduce maintenance time and overall cost. More robust structures provide the added durability to handle the increased weight and productivity.

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.
