Cat® D8R Designed for Durability in Tough Applications, Operator Comfort and Safety, and Easy Routine Maintenance

Cat® D8R Designed for Durability in Tough Applications, Operator Comfort and Safety, and Easy Routine Maintenance

For Release In Africa, Middle East, CIS: March 2015
Release Number: 38PR15

Since 1935, the Cat® D8 crawler dozer has proved its mettle by taking on the most demanding applications in the most severe operating conditions—whether rock, desert sand, or extreme cold. The new D8R combines the rugged, built-in durability and reliability of its predecessors with features that further enhance operator safety and comfort, while simplifying routine maintenance.

The D8R’s new cab, with an integrated Roll-Over Protective Structure (ROPS) and enhanced visibility (especially to the sides of the machine), is quieter and more effectively pressurized to keep out dust for a cleaner operating environment. New pilot-operated controls for the implement hydraulic system reduce operator effort and provide more consistent, precise, and responsive operation.

Added convenience features include single-handle control for direction/range selection and tiller-bar steering that allows the D8R to work more precisely around structures, grade stakes, or other equipment. A redesigned instrument panel allows the operator to read analog-type gauges at a glance, and the Cat Electronic Monitoring System keeps the operator informed about machine operating conditions.

Serviceability, telematics, added value

For fast, simple routine maintenance, the D8R is designed with grouped service points, sight gauges, fast-fuel-fill capability, and easy access to the engine compartment. The machine’s modular design allows easy access to major power-train components for service or replacement, and individual radiator cores are quickly replaced. The net result is savings in cost and downtime.

The Product Link™ telematics system, working through the Caterpillar VisionLink® user interface, provides timely access to critical machine data, such as location, event codes and service hours.

For optimum customer value, the D8R is designed for more than one life. Cat Certified Rebuild and Remanufacturing options can extend the machine's useful life and further reduce lifetime owning and operating costs.

Premium features

Using the field-proven Cat 3406C DITA engine with a reliable mechanical fuel-injection system, the D8R has the power to move the most stubborn materials, and the engine’s Advanced Modular Cooling System delivers optimum cooling capacity with increased airflow to work in the most demanding environments. Available for the D8R are Desert and Waste Handler arrangements that are specially equipped to work more efficiently in these harsh environments.

With differential steering, the D8R maintains power to both tracks through turns, resulting in consistent blade loads and higher production, and the load-sensing hydraulic system, using a dedicated implement pump, continually adjusts hydraulic power for optimum efficiency.

In addition, the D8R’s undercarriage, with the Caterpillar elevated-sprocket design, is fully suspended to provide maximum ground contact, especially in uneven terrain, resulting in greater traction, less track slippage, better balance, and a smoother ride. The D8R is available in Standard and Low Ground Pressure (LGP) configurations, and can be equipped with a variety of blades including universal, semi-universal, and angle configurations. Please consult with your Cat dealer for models and configurations available in your area.
