Added productivity and up to 10 percent fuel savings, delivering up to 18 percent better dozing efficiency than previous model D8T.
Move up to 13 percent more material per pass with the largest standard blade in the size class (10.3 m³).
Keep working, even in high temperatures, with increased cooling capability.
Push in second gear for more dozing productivity.
Save fuel with a hydraulic demand fan that reduces speed in cooler conditions. Optional reversing capability for high debris conditions.
Auto Shift automatically down shifts to the most efficient gear based on load, adding to overall fuel savings.
BUILT TO PERFORM
Cat C15 engine delivers more horsepower, with more than a decade of proven reliability in a wide range of working conditions.
More efficient power train, hydraulic fan and new radiator increase ambient capability up to 23 percent.
Purpose-built Desert Arrangement includes added cooling performance and more protection for working in extremely sandy or abrasive conditions.
Optional cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
Easier maintenance access with wider engine panel doors and optional bottom guard access panels.
Note: Comparisons to previous model D8T
OPERATOR COMFORT AND CONTROL
Optional electro-hydraulic controls reduce operator effort, improve precision and response, and enable Cat GRADE technologies.
Optional Liquid Crystal Display (LCD) places machine data, settings menus, grade control data and more conveniently in front of the operator (where available).
LCD display is rear-camera-ready for added safety.
TECHNOLOGY THAT PUSHES PROFITS
Standard Slope Indicate displays machine cross-slope and fore/aft orientation right on the main display.
Cat GRADE with Slope Assist™ automatically maintains pre-established blade position without a GPS signal
Versatile, scalable Cat AccuGrade™ is an optional dealer-installed grade control system. Choice of Laser, Global Navigation Satellite System (GNSS) or Universal Total Station (U TS) so you get the right level of accuracy to match your job requirements.
Product Link™ collects machine data that can be viewed online through web and mobile applications
Access information anytime, anywhere with VisionLink® and use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve security on your job site
BECAUSE UPTIME COUNTS
Cat dozers are designed with features like wide engine panel access doors to minimize maintenance and repair time.
Cab-mounted air conditioning condenser supports better system performance, improved engine cooling and serviceability.
Ecology drains help reduce spills during power train fluid changes.
Fast fuel system at ground level, with positive fuel shut-off, helps prevent fuel spillage/waste and speeds refueling for more uptime.
High-speed oil change attachment to help make servicing even faster.
When you need repairs, Cat dealers and our unmatched Caterpillar distribution network excel at getting you the right parts you need quickly.
Maximize your equipment investment with services like Customer Support Agreements, preventive maintenance programs and guaranteed maintenance contracts.
Remanufactured parts offer a lower cost replacement option.
Certified Rebuild gives a “second life” for your machine.
HANDLE THE DESERT HEAT
Equip your dozer for the demands of desert applications with features ideally suited to support machine performance and service life in extremely sandy or abrasive conditions, choose from these options:
Precleaner Turbine air intake system prevents nearly all of the heavier-than-air particles from entering the system, which results in longer air filter life, more efficient engine performance and decreased maintenance expenses.
Engine enclosure doors are solid at the bottom to help reduce the amount of sand carried into the engine compartment for improved cooling and reduced cleanout time.
Specially coated fan and radiator core protection help resist abrasion. Reversing function is disabled on the hydraulic demand fan.
Sealed bottom guard and added seals help keep fine abrasive particles out of components.
Bottom guard access panels facilitate cleanout without removing bottom guard.
Wear plates can be replaced to give you longer blade life when working in abrasive conditions.
Cab-mounted air conditioning condenser recommended to help improve system performance and aid serviceability.
