Benefits & Features


    • Every Cat engine equivalent to Tier 2/Stage II is equipped with a combination of proven electronic, fuel, air and aftertreatment components. The right technologies fine-tuned for the right applications result in:
    • Proven electronic, fuel, air and aftertreament components for peak performance, longevity and emissions control.
    • Improved fuel economy.
    • Reduced maintenance costs.
    • 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 optimizes airflow, power, efficiency and reliability.
    • The 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.* Gear shifts are configured to maintain direct drive lock-up and minimize dropping into converter drive to maintain ground speed and gradeability.
    • Large capacity torque converter ensures maximum power delivered to drive train.
    • Engine compression brake improves retarding response and increases retarding power.


    • Advanced Automatic Traction Control (AATC) proactively applies inter- and cross-axle differential locks ‘on-the-go.’ Operators are freed from this function to concentrate on driving/loading/dumping. 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 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 lost machine efficiencies caused by improper manual operation of the differential clutches and reducing the tire wear.
    • Automatic Retarder Control (ARC) automates the retarder for the operator. Like AATC, a number of machine operating aspects are monitored. If required, the engine compression brake is engaged automatically to control machine speed when descending a grade. The system can help towards eliminating engine overspeed, improving safe machine operation and reducing cycle times, yet still having the flexibility of manual control if needed.
    • New Assisted Hoisting Control automates the dumping function. Flick the new body raise/lower switch and the machine will apply the service brakes, switch the transmission to neutral and raise the body at the required engine rpm. Lowering the dump body is done the same way, flick the switch and the machine will lower the body and place it in float.


    • All three axles promote stability using oscillating a-frames with lateral tie rods. Operate at productive speeds with confidence while virtually eliminating impact loads on truck components.
    • The front suspension oscillates controlled by large-bore, low-pressure cylinders to assist in a smooth ride. An A-frame with lateral tie rod controls sideways movement and aids stability.
    • The rear suspension features a walking beam and long-life suspension mounts optimizing ride and load retention.
    • New fully enclosed wet disc brake systems inside of axles keeps contaminants out extending machine life and ensuring uptime.
    • Hill assist reduces potential 'roll-back' on grades. If an operator stops the machine on a grade, when taking his foot off the service brake pedal the machine will automatically hold the service brakes on for a number of seconds to prevent the machine from rolling backwards.
    • 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.


    • Spacious cab delivers comfort all shift long and is 7dB quieter than prior model.
    • Unique combination hoist/transmission lever is intuitive and enhances cycle times with fewer control movements.
    • Trainer/passenger seat is fully padded with wide, retractable seat belt for security and comfort.
    • New large side storage box is heated/cooled by the HVAC system.
    • Air-suspension seat offers greater comfort, with a greater range of adjustments. Fore/aft isolation dramatically reduces vibrations and jolts. Every operator will find a adjustments to ensure comfort and control all shift long.
    • Standard cooling/heating system ensures comfort in all conditions.
    • Optional four-point seat belt is available to help operator stay in position and comfortable in rugged terrain.
    • Integrated, wrap-around dash means all gauges and controls are easy to monitor and access. Automotive feel with Caterpillar's renowned industrial strength.
    • The updated touch screen dash mounted display allows the operator to monitor and adjust various levels of machine performance and condition, 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 rearview camera.
    • Optional Bluetooth™ entertainment system allows operator to stay in hands-free phone contact.


    • Box section front frame absorb is stiff to handle torque loads. Frame design decreases stress at the hitch and optimizes suspension geometry.
    • Rear frame features twin-box construction minimizing stress points and enhancing service life.
    • The articulating hitch provides the truck with steering articulation, and the oscillation ensures all-wheel ground contact in rough terrain.
    • Field proven two-piece hitch construction features a durable cast steel head bolted to a hard wearing forged steel tube.
    • Dump body design provides a large target area for consistent high-load carrying capacity increasing productivity. Diverging flow when dumping aids material flow out of the body maximizing productivity and avoiding carry-back.
    • The output transfer gear distributes drive to the tractor and trailer and includes a wet clutch differential lock for optimum traction in poor underfoot conditions.
    • The full power hydraulic brake system actuates enclosed, oil-immersed, multi-disc, multi-plate brakes with independent front and rear circuits and accumulators. This dual-circuit, all wheel braking system provides the braking performance required to support maximum productivity.
    • The parking brake is located on the center axle in an elevated position, it is spring applied and hydraulically released.


    • Cat Product Link wirelessly connect you to your equipment, giving you valuable insight into how your machine or fleet is performing. The system tracks location, hours, fuel usage, productivity, idle time, and diagnostic codes through the online VisionLink user interface so you can make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
    • Cat Production Measurement brings payload weighing to the cab to help optimize job site efficiency and productivity. Operators can view real-time load weights on the integrated display and know precisely when target is achieved, while cab-mounted external payload lights on all four corners signal the loader operator when to stop, reducing the risk of machine overloading. Operators can track daily productivity from the cab, with quick access to truck payload weights, loads and cycle counts, and daily totals; or remotely via LINK technologies.
    • Cat Detect with Stability Assist warns the operator if machine is approaching a pre-set angle during operation; when driving and tipping. If using the assisted hoist, the machine will stop hoisting the body and give an audible and visual warning. The system monitors angles of tractor, trailer and grade independently. This increases operator awareness of machine stability during operation. All tractor and/or trailer rollover events are logged and reported via VisionLink.


    • Caterpillar design, manufacturing and customer service help ensure peak performance and uptime.
    • Long service intervals keep your machine operating.
    • Lubrication points are grouped near the hitch for fast, easy routine maintenance.
    • Universal joints are sealed and lubed for long life.
