MOTEUR
Comfort and productivity
BENEFITS AND FEATURES
An updated cab, with an Integrated Roll Over Protection Structure (ROPS), gives operators greater all around visibility to enhance safety and productivity. It offers a quieter interior, with improved pressurization to help keep dust out for a cleaner operating environment. The redesigned instrument panel is easy to read, showing fuel level and engine RPM, as well as temperature levels for power train oil, hydraulic oil and engine coolant. The Cat Electronic Monitoring System keeps the operator informed about machine operating conditions. Three-level alert indicators monitor coolant flow, coolant temperature, engine oil pressure, transmission oil temperature, alternator low voltage and transmission/hydraulic oil filter restriction.
Implement and Steering Controls All D8R controls are ergonomically designed for low-effort and ease of operation.
- The operator uses a single handle control to perform all direction and gear selection for ease of operation. The tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines.
- New pilot hydraulic implement controls reduce operator effort and offer more consistent, precise and responsive operation.
Built to get the job done
BENEFITS AND FEATURES
Engine A powerful Cat 3406 diesel engine allows the D8R to doze through tough material. This field proven mechanical engine also features a modular design for ease of service.
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.
Planetary Power Shift Transmission The proven mechanical transmission features three speeds forward and three speeds reverse. Large diameter, high capacity, oil-cooled clutches provide higher torque capacity and increase service life. Modular components offer easy service access.
Load Sensing Hydraulics Field-proven system senses the load and continuously adjusts hydraulic power to maximize your efficiency. A dedicated implement pump ensures adequate available hydraulic power.
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.
Cooling System The Advanced Modular Cooling System has excellent cooling capacity with increased air flow, allowing the machine to work in the most demanding environments. Two-pass cooling increases the relevant surface area for maximum cooling capacity. Individual radiator cores can be quickly replaced for ease of service.
Tough from the inside out
BENEFITS AND FEATURES
Structures The foundation of every Cat dozer is a rugged mainframe built to absorb high impact shock loads and twisting forces. Castings add strength to the main case and equalizer bar saddle. The pivot shaft runs through the mainframe and connects the roller frame for independent oscillation. This provides strength, and allows the machine to better follow ground contours for maximum traction and operator comfort. The D8R features the tag-link design to mount the blade closer to the machine for excellent maneuverability, balance and blade penetration. The tag-link provides solid lateral stability and eliminates the need for diagonal bracing.
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 landfill 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.
Rear Implements Single and multi-shank adjustable parallelogram rippers are made to penetrate tough material fast and rip thoroughly for use in a variety of materials. Single-Shank ripper depth can be adjusted from the seat using an optional pin puller. An optional push block provides additional weight when needed for tougher conditions. Multi-Shank rippers tailor the tractor to the material by using one, two or three shanks. Rear counterweights optimize balance for backing up steep slopes or increasing performance in heavy dozing applications. The D8R can also be outfitted with a winch. Please see your Cat dealer for available options to suit your applications.
Undercarriage The elevated sprocket design helps protect major components from harsh impacts and provides a modular design for convenient service. A fully suspended undercarriage provides more ground contact, especially in hard, uneven terrain. Greater traction means less slippage, better balance and a smoother ride. An optional non-suspended undercarriage is available for working in low to moderate impact abrasive conditions. Sealed and Lubricated Track is standard on the D8R. The Cat Positive Pin Retention system is designed for high-impact and high load applications. The exclusive Caterpillar design locks the link to the pin to ensure internal lubrication between track pin and bushing is maintained. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components for reduced owning and operating costs.
When uptime counts
BENEFITS AND FEATURES
Ease of Service Simple mechanical systems support easy maintenance. Engine, cooling system, power train and undercarriage components are modular, designed for easy repair or maintenance access. The D8R is designed to make daily inspections and routine maintenance more convenient. Service points are grouped and ground-level sight gauges let you inspect fluid levels at a glance. Optional fast-fill fuel and engine oil attachments help you get back to work more quickly.
