• Delivering better fuel economy with minimized maintenance costs while providing the same great power and response.

Advanced Mechanical Electronic Unit Injector (MEUI™-C) Injector

Advanced MEUI-C injector platforms deliver increased injection pressures and more precise fuel rates. These durable injectors enhance responsiveness while controlling soot.

Innovative Air Management

All Cat engines feature innovative air-management systems that optimize airflow and enhance power, efficiency and reliability.

Cat NOx Reduction System (NRS)

The NRS captures and cools a small quantity of exhaust gas, then routes it back into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Aftertreatment Technologies

The aftertreatment solution utilized for Tier 4 Final and Stage V products is the next evolutionary step for Cat engines with ACERT Technology. To meet the additional 80 percent reduction in NOx emissions required by Tier 4 Final and Stage V emission standards, Caterpillar engineers only needed to add one new system to the already proven aftertreatment solution in use, Selective Catalytic Reduction (SCR).

Diesel Exhaust Fluid (DEF)

Cat engines equipped with an SCR system inject Diesel Exhaust Fluid (DEF) into the exhaust to reduce NOx emissions. DEF is a precisely mixed solution of 32.5 percent high purity chemical grade urea and 67.5 percent de-ionized water.

Engine Compression Brake

The engine compression brake improves retarding response and increases retarding power for controlled descent of grades.

Transmission – Class Leading Transmission Technology

See more

The CX38B Cat High Density Power Shift (HDPS) nine-speed forward, two-speed reverse transmission, designed specifically for articulated trucks, features Advanced Productivity Electronic Control Strategy (APECS) and Electronic Clutch Pressure Control (ECPC) that deliver smooth gear changes with improved acceleration and higher productivity.

• Speed hold/limiting function allows the machine speed to be limited in 1 km/h or 1 mph steps to conform to site speed restrictions.

• Gearshifts are configured to maintain direct drive lock-up, and reduce dropping into converter drive. Decreasing the use of torque converter drive aids in maintaining ground speed and gradeability.

• Variable gearshift points are used based on the operating conditions, which also aid in maintaining ground speed during gear changes on grades.

Automatic Features – Ease of Use, Improved Performance

See more

Advanced Automatic Traction Control (AATC)

Proactive application of the inter- and cross-axle differential locks is ‘on-the-go’ and fully automatic. The operator does not have to think about when and where to engage either diff lock. Sensors monitor the machine and wheel speeds, enabling instant response in high rolling resistance conditions. Operation is seamless and smooth, eliminating wheel slip for maximum traction and therefore productivity. Clutches are automatically disengaged when ground conditions allow, maximizing efficiency when steering or when on uneven ground. AATC reduces tire and driveline abuse, eliminating machine inefficiencies caused by improper manual operation of the differential clutches and reducing the cost of premature tire replacement.

Automatic Retarder Control (ARC)

Fully automatic retarder control removes the need for any operator interaction. As with AATC, a number of machine operating aspects are monitored. The system can help towards eliminating engine overspeed yet gives the flexibility of manual speed adjustment, if necessary.

Assisted Dumping System

Tipping of the dump body can be done automatically with the new Assisted Hoisting Control. Full manual control is also possible.

Hill Assist

Hill Assist reduces potential ‘roll-back’ on grades. If an operator stops the machine on a grade, when taking the operator’s foot off the service brake pedal, the machine will automatically hold the service brakes to prevent machine from rolling backwards.

Waiting Brake

Waiting brake applies the service brakes when neutral gear is selected, allowing quick and easy control of the machine at the load or dump area.

Ease of Operation – Designed for Operators, by Operators

See more

Control Layout

The new cab is designed to make all aspects of machine operation as simple as possible for every operator. The controls and gauges are easy to read and straightforward to use, allowing the operator to focus on safe machine operation while maintaining productivity.

Combined Hoist/Transmission Lever

Unique to Cat articulated trucks, the combined hoist/transmission lever provides easy, intuitive control of gears and hoist functions.

The new assisted hoist system gives improved control to the operator, allowing for faster cycle times and less control movements.

Offering both automatic and manual options, the system gives operators flexibility to choose their preferred method of control. When using the automatic system to tip a load, when flicking the switch to the ‘raise’ position, the machine neutralizes the transmission, applies the service brakes and hoists the body to maximum angle at the required engine rpm. When flicking the switch to the ‘lower’ position, the machine will automatically lower the body and place it in float. Both raise and lower functions feature automatic speed reduction and cushioning of the body at the limits of its movement, reducing forces that could otherwise cause shock loads.

Automatic use can reduce operator interactions by up to 50 percent, compared to the previous model, depending on the site tipping procedure. Also incorporated into the lever are waiting brake, transmission hold, machine speed limiter and parking brake selection. This gives operating a more automotive feel. No separate park brake switch is now needed; you just push the lever into park.

Dashboard

The newly styled and updated dash puts all controls within easy reach of the operator. It features LED illuminated rocker switches for easy use in all operating conditions. The fit and finish delivers an automotive feel with the industrial strength you would expect from Caterpillar.

Touchscreen Display

The updated touchscreen dash mounted display allows the operator to monitor and adjust various levels of machine performance and conditions, as well as machine warning categories. These include configuration settings, operator and machine totals, service information, various machine status parameters, machine payload information (when fitted), stability assist, and the video feed from the camera.

Bluetooth® Stereo Connectivity

Make and receive hands free calls via the optional Bluetooth equipped stereo with clearer quality due to the quieter cab and upgraded speakers.

Spacious Two-Person Cab

The large open cab offers a comfortable working space for both the operator and an additional person (e.g. training purposes). The second seat is fully padded with a backrest and a wide, retractable seat belt for a secure and comfortable ride. Positioned adjacent to the operator, the forward facing seat gives the trainer a clear view of the instrument panel, controls and the road ahead.

Increased and Improved Storage

A new large side storage box is heated or cooled by the heating, ventilation, and air conditioning (HVAC) system depending on operator preference. New additional storage is now also available under the second seat. Twin cup holders and multiple storage spaces have also been introduced to help give operators an uncluttered workspace.

Air Suspension Seat

The new air suspension seat gives an increased range of adjustments over previous offerings including fore/aft isolation, which dramatically reduces horizontal vibrations and jolts. This provides a greater number of operators with the ability to tailor their seating position for a more comfortable working day.
