Built to get the job done

A Cat C15 ACERT engine gives you the power and reliability you need to get the job done. Improved fuel economy over Tier 4 Interim/Stage IIIB/Japan 2011 (Tier 4 Interim) and efficient use of Diesel Exhaust Fluid (DEF) gives you excellent overall fluid efficiency.

Differential Steering

Differential Steering maintains full power to both tracks for best-in-class turning, even with a full blade load. When one track speeds up, the other slows down an equal amount, so you have better maneuverability and faster cycle times. You also get better load capacity, power and speed control in soft conditions because both tracks are powered during turns.

Load Sensing Hydraulics

Field-proven load-sensing hydraulics continuously adjust hydraulic power based on load to maximize your work tool efficiency.

Torque Divider

A single stage torque divider sends 70 percent of engine torque through a converter and the other 30 percent through a direct drive shaft so you get more power to the ground, more efficiently.

Cooling System

The radiator, Air To Air Aftercooler (ATAAC) and hydraulic oil cooler are packaged in a single plane, making cleanout easier. Durable, aluminum bar plate construction gives you superior heat transfer and corrosion resistance. Six fins per inch on the standard core allow debris to pass through and help reduce plugging.

In cooler conditions, the hydraulic demand fan reduces speed to conserve power, save fuel and decrease sound levels. An optional reversing fan is available for high debris conditions.

Advanced Productivity Electronic Control System (APECS)

The Planetary Power Shift Transmission uses integrated electronic controls to automatically modify shift points based on load and operating conditions. The result is smoother shifting overall, as well as greater benefits from Enhanced Auto Shift.

Enhanced Auto Shift

Enhanced Auto Shift is a standard feature that allows your operator to select the optimum ground speed for the job. It also helps you save fuel by automatically choosing the most efficient gear based on load.

Selectable Electro-Hydraulic Maps

Customizable E-H maps allow you to set the implement response/speed levels to match operator preferences and tailor the machine to individual applications.

Comfort and productivity

The latest D8T offers operators added comforts like a quieter cab, adjustable armrests and a heated/ventilated seat option. A seat belt indicator light helps remind you to work more safely.

A new color touch-screen display puts the machine’s programmable control features right at your fingertips. Control exterior lighting, activate the reversing fan and set productivity features like Autocarry™, Auto Rip and Enhanced Auto Shift. You can also access machine performance settings, diagnostics and much more. For complete information about functions and programming, please see the D8T Operation and Maintenance Manual.

Implement and Steering Controls

  • A single ergonomic handle with a thumb roller controls direction, turning, forward/reverse shifting and gear selection. Tiller style control helps you work more precisely in tight spaces.
  • Low-effort dozer lever with electro-hydraulic controls helps you work more comfortably and get precise work tool control. When equipped, single-handle convenience also controls functions like AccuGrade and Dual Tilt.
  • A ripper control with rigidly mounted hand grip provides firm support for the operator even when ripping in the roughest terrain.
  • Implement Lock-Out prevents inadvertent operation of hydraulic attachments when activated by the operator or automatically when the operator is not present.

Proven, integrated solutions

Emissions reduction technology on the D8T is designed to be transparent, with no action required from the operator. Regeneration runs automatically in the background while you work.

Aftertreatment Technologies

To meet the additional 80 percent reduction in NOx emissions required by Tier 4 Final/Stage IV/Japan 2014 (Tier 4 Final)/Korea Tier 4 Final emission standards, Caterpillar engineers added Selective Catalytic Reduction (SCR) to the already proven aftertreatment solution.

Diesel Exhaust Fluid

Selective Catalytic Reduction utilizes Diesel Exhaust Fluid (DEF), which can be conveniently refilled when you refuel. A gauge on the dash shows your fluid level. The D8T offers excellent fluid efficiency. Across a variety of applications, the D8T typically has used DEF at a rate of 2-3 percent of fuel consumption.

When the machine is turned off, a pump will automatically purge the DEF lines to help prevent the fluid from freezing in the lines and pump. A symbol on the dash and a light/symbol on the Ground Level Service Center indicate when the purge is complete and that it is safe to turn off the electrical disconnect. If the engine/aftertreatment temperatures are high, a delayed engine shutdown will activate automatically to cool the machine and then purge the lines. For complete aftertreatment information, please refer to your machine’s Operation and Maintenance Manual.

Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you’ll get more information and insight into your equipment and operations than ever before.

Cat Connect technologies offer improvements in these key areas: Equipment Management – increase uptime and reduce operating costs. Productivity – monitor production and manage job site efficiency. Safety – enhance job site awareness to keep your people and equipment safe.

LINK Technologies

LINK technologies wirelessly connect you to your equipment giving you access to essential information you need to know to run your business. LINK data can give you valuable insight into how your machine or fleet is performing so you can make timely, fact-based decisions that can boost job site efficiency and productivity.

Product Link/VisionLink

Product Link is deeply integrated into your machine, helping you take the guesswork out of equipment management. Easy access to timely information like machine location, hours, fuel usage, idle time and event codes via the online VisionLink user interface can help you effectively manage your fleet and lower operating costs.

GRADE Technologies

Cat Connect GRADE technologies help you hit target grade faster and more accurately. Finish jobs in fewer passes, and with less operator effort, saving you time and helping you increase profit.

Cat Slope Indicate

Cat Slope Indicate (Standard) displays machine cross-slope and fore/aft orientation on the primary monitor, helping operators work more accurately on slopes.

Cat Grade Control 3D

Cat Grade Control 3D (Optional) is a factory-integrated grade control system that enables operators to improve grading efficiency, accuracy and productivity. The system automates blade movements, reducing manual operator inputs by as much as 80 percent. Experienced operators can maintain peak efficiency levels throughout more of the work day, while less experienced operators can be more productive faster.

The integrated design moves the antennas to the top of the cab, eliminating masts and cables traditionally on the blade. 3D mapping of blade and tracks reduces the need for grade checkers and staking, enhances safety and reduces labor costs.

Cat Grade Control is used in fine grading and production dozing applications. Three operating modes – Rough Grade, Grade Protection, and Grade Control – enable consistent grades. Integrated, productivity enhancing features – Autocarry, Auto Blade Assist, and Automatic Ripper Control – turn the D8T into a high production dozing system.

Cat AccuGrade

AccuGrade (Optional) is a dealer-installed aftermarket grade control system that provides higher accuracy capabilities by adding laser, GPS and UTS technology when required. The factory AccuGrade Ready Option provides optimal mounting locations, brackets, and hardware and simplifies installation. Deep Integration optimizes machine and system performance to maximize productivity.

Tough from the inside out

The D8T is built on a tough mainframe designed to absorb high impact shock loads and twisting forces. A fully suspended undercarriage provides more ground contact, especially in hard, uneven terrain. Greater traction means less slippage, better balance and a smoother ride.

The elevated sprocket design helps protect major components from harsh impacts and provides a modular design that is convenient to service. The Tag-Link brings the blade closer to the machine for precision, lateral stability and constant breakout force, regardless of the blade height.

Bulldozers

High tensile strength steel, with a strong box-section design, stands up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability. Optional rock guards and deflector shields help protect cylinders. High-Capacity Universal, Semi-Universal and Angle Blades are available, as well as special blades for coal and woodchip stockpile applications.

Optional Dual Tilt improves load control and allows the operator to optimize the blade pitch angle for better balance and productivity. Tilt the blade forward for better penetration, then tilt back to increase carrying capacity. Auto Blade Assist is standard with Dual Tilt to increase efficiency and reduce operator workload.

Undercarriage

Heavy Duty undercarriage is standard and is well suited to aggressive applications like land clearing, side-slopes, or working in rocky or uneven terrain.

Optional SystemOne™ undercarriage is designed to work and wear as a system for longer life and lower costs in high abrasion and low to moderate impact applications.

A variety of track shoe types and widths are available to help you optimize your undercarriage for the type of work you do.

Rear Implements

To help match your dozer to the task at hand, you can outfit your D8T with a single-shank ripper, multi-shank ripper, winch, drawbar or rear counterweights.

Ask your Cat dealer for available options to help you optimize your machine for the work you do.
