Cab and Controls

Productivity, safety, comfort

Operator Environment

The D5R features an isolation-mounted, pressurized cab that reduces noise and vibration. Large, single pane windows offer good views all around the machine for maximum productivity and enhanced job site safety. The Comfort Series seat features fully adjustable positioning and armrests to provide a comfortable platform when working on steep grades or slopes. Heating and air conditioning vents evenly distribute airflow within the cab. The cab is pre-wired for a radio, equipped with two speakers, an antenna and a radio mount recessed in the headliner. The D5R also features an Open ROPS Canopy (featured right) that offers good views all around the machine and a fully adjustable Comfort Series seat. Gauges and warning lights on the in-dash instrument cluster are easy to read, even in direct sunlight. The Cat Monitoring System Display gives operators and service technicians easy access to operating and maintenance information. The system provides three levels of warning and system monitoring so the operator can stay informed and still concentrate on the job.

Dozer and Ripper Controls

All D5R controls are ergonomically designed for low-effort and ease of operation. The dozer and ripper control levers feature Electro-hydraulic for added operator comfort and precise control.

Throttle Rocker Switch

With the touch of a finger, the rocker switch activates high or low idle. A decelerator pedal gives the operator full control of engine speed when the rocker switch is in the high idle position. Engine speed can also be easily set in any range between high and low idle by simultaneously using the decelerator pedal to set the desired speed and pressing the throttle switch in for three seconds.

Steering and Transmission Control

The operator uses a single handle control to perform all direction and gear selection. The tiller bar control allows the operator to work more precisely in close areas around structures, grade stakes and other machines. Differential Steering provides the finest modulation in the industry.

Work Tool Lock-Out Switch

The work tool lock-out valve prevents inadvertent operation of the hydraulic work tool attachments for added safety.

Engine

Power and reliability

Caterpillar is one of the world’s leading engine manufacturers. Every component of a Cat® engine is carefully designed to maximize durability and reliability. Precise controls optimize power and fuel efficiency while reducing emissions. Modular design and advanced electronic diagnostics enhance the engine’s serviceability.

ACERT Technology

The D5R features a Cat C6.6 engine with ACERT™ Technology. A series of Caterpillar innovations provide advanced electronic control, precision fuel delivery and refined air management, resulting in outstanding performance and lower emissions. To help customers work within expanding global regulatory requirements, the C6.6 engine with ACERT Technology can reach equivalent EPA Tier 3 or EU Stage IIIA emissions levels.

ATAAC

The air-to-air aftercooler (ATAAC) - part of the advanced air management system - brings cool air to the engine. This increases life, reduces emissions, and helps maximize fuel efficiency.

Fuel Delivery

Multiple injections where fuel is introduced in the combustion chamber in a number of precisely controlled micro-bursts. Injecting fuel in this way allows for precise shaping of the combustion cycle directing the injectors to deliver precise quantities of fuel at exactly the right times during combustion.

Cat Advanced High Efficiency Oil Filter

Advanced oil filters provide outstanding contamination control for a much cleaner running engine. The advanced filtration is accomplished without the shorter change intervals often required with other brands.

Cooling System

The all new cooling system includes engine radiator, Air-to-Air After Cooler (ATAAC), and hydraulic oil cooler. Engine radiator consists of two units of bar plate cooler, which are connected at the top with hose. The aluminum bar plate construction provides improved durability to debris plugging, abrasion and corrosion resistance.

Power Train

Powerful efficiency

The power shift transmission and differential steering are matched with the C6.6 engine to deliver outstanding power and reliability. The integrated system efficiently puts more power to the ground, utilizing more of the available horsepower, so you get more done with less.

Differential Steering System

Differential steering puts you on the leading edge of productivity by maintaining power to both tracks while turning. When one track speeds up, the other slows down an equal amount. Maneuverability - especially with large blade loads - is improved, as well as cycle times in other applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes because both tracks are powered during turns. A single tiller bar controls all directional and speed functions for ease of operation.

Planetary Power Shift Transmission

The transmission includes three speeds forward and three speeds reverse, featuring thick, large diameter, high capacity, oil-cooled clutches. These clutches provide higher torque capacity and increase service life. Modular transmission and differential slide into rear case for servicing ease, even when a ripper is installed. An oil-to-water cooler provides maximum cooling capacity, and forced oil flow lubricates and cools clutch packs for maximum clutch life.

Structures

Rugged design for maximum service

The foundation of every Cat dozer is a rugged frame built to absorb high impact shock loads and twisting forces. The frame has a reinforced saddle and a welded front cross-member. Both add strength to the frame to better handle lateral and twisting forces. The pivot shaft is bolted to the mainframe and connects to the rear roller frames to allow independent oscillation. The pivot shaft distributes impact loads throughout the case, reducing bending stresses on the case. This design eliminates alignment problems and the need for diagonal braces on the roller frames. The track roller frames are welded and box-section in design, which provides strength and resistance to bending and twisting with added reinforcement where operating loads are the highest. The pinned equalizer bar gives the roller frames the ability to oscillate up and down to better match ground contours for maximum traction and operator comfort. Bolted end pins offer longer life and reduce downtime with improved serviceability and reliability. Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer component life. Modular power train components make it quick to remove and repair the transmission, final drives, steering differential or brakes. Modular undercarriage components simplify service. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components. This reduces owning and operating costs, and saves raw materials and natural resources.

Undercarriage

Proven productivity

Since its ground-breaking introduction in 1978, the Cat elevated sprocket undercarriage arrangements allow optimized balance for best possible performance in each application. This is a field-proven design that offers outstanding machine performance and longer component life. Ground and implement shock loads are transferred to the mainframe to protect final drives, axles and steering components from harsh impacts for longer component life. The elevated sprocket design gives the operator excellent sight lines to the blade, sides and back of the machine. However, machine center of gravity remains low, offering excellent stability, balance and traction. Modular power train components make it quick to remove and repair the transmission, final drives, steering differential or brakes. Modular undercarriage components simplify service. Lifetime lubricated idlers and track/carrier rollers provide the ability to re-use internal components and rebuild or reshell components. This reduces owning and operating costs, and saves raw materials and natural resources.

Heavy Duty Undercarriage

Standard Heavy Duty undercarriage components are designed for extended wear life in abrasive conditions and high impact applications like forestry, side-slopes, or working in rocky or uneven terrain. Heavy duty track is designed for enhanced penetration. The leading and trailing edges of each track shoe overlap the adjacent shoe to increase durability and component life. Two (2) Undercarriage Arrangements are available:
  • XL arrangement - More track positioned to the front provides a balanced machine for general duty and fine grading applications.
  • LGP arrangement - Specifically designed to work in soft or wet conditions. Wide track shoes, long track frames, and a wider machine gauge increases ground contact area and reduces ground pressure for improved stability requiring flotation in swampy conditions.

Track Shoes

Moderate Service and Extreme Service track shoes are available to help optimize the machine based on its most frequent applications. Proper track shoe selection helps minimize wear for optimal undercarriage life - especially in high impact or highly abrasive conditions.

Work Tools

Equipped for the job

Load Sensing Hydraulics

Field-proven, load-sensing, electronic controlled hydraulics respond to operating requirements by automatically and continually adjusting hydraulic power to maximize work tool efficiency.

Cat Blades

Blade designs feature a strong box-section design, made from steel with high tensile strength to stand up to the most severe applications. Heavy moldboard construction and hardened bolt-on cutting edges and end bits add strength and durability.
  • Semi-Universal Blade - designed for superior load retention and penetration in tightly packed materials. Ideal blade for use in construction applications where penetration of material is required as well as retention to carrying and spreading loads.
  • Angle Blade - Can be positioned straight or angles 25 degrees to either side manually. Designed for side casting, pioneering roads, backfilling and cutting ditches.
  • Power Angle and Tilt Blade - Can be positioned in variable angles from the operator’s station.

Multi-Shank Ripper

Serviceability

Stay up and running

Cat machines are designed with serviceability in mind. Modular components, easy access to regular service points and features that enable quicker diagnostics all add up to less maintenance time and more time on the job.

Cat Monitoring System

The D5R features a monitoring system that provides feedback to operators with easy-to-read gauges and warning lamps that allows the operator to concentrate on the job at hand. With the use of a Cat Electronic Technician (ET), your Cat dealer can determine historical performance parameters of the machine. The Cat Monitoring System is designed to:
  • Reduce downtime
  • Provide warning feedback on operational events
  • Provide feedback on machine performance events

Scheduled Oil Sampling (S·O·SSM) Analysis

Monitor machine health and identify key maintenance needs before they lead to downtime through Cat Scheduled Oil Sampling. Cat machines feature live sampling ports for the engine oil, power train hydraulics and coolant. Cat oil sampling offers accurate analysis using tests designed by Caterpillar for Cat products, as well as knowledgeable interpretation of the results.

Built to be Rebuilt

Major components on the D5R are built to be rebuilt, extending the useful life of the machine. Machine and component rebuilds save money, and offer a sustainability element by saving raw materials and natural resources. See your Cat dealer to learn more about rebuild options.
