Advantages and Features

PROVEN RELIABILITY

        
  • Cat C13A engine delivers proven reliability across a variety of applications.
    •     
  • Terrain-based throttle control smooths throttle input over rough terrain to improve ride quality.
    •     
  • Enhanced reliability through commonality and design simplicity with long life to overhaul.
    •     
  • Minimized impact of emission control system allows excellent response and ample power.
    •     
  • Engine compression brake improves response and increases retarding power for controlled descent of grades.

EXPAND YOUR CAPABILITIES

        
  • The truck can eject and spread the material while moving, reducing additional spreading and dozing equipment. “On-the-go” ejecting results in faster cycle times.
    •     
  • Ejecting the load without raising the body maintains machine stability, allowing load dispersal on inclines, side slopes, and in very soft underfoot conditions, especially on landfill sites.
    •     
  • The truck can eject in areas with reduced overhead clearance, such as around overhead lines or in tunneling and underground operations.
    •     
  • The body design virtually eliminates material sticking to the body, which increases productivity, improves fuel efficiency, and lowers cost per ton.
    •     
  • The ejector blade is made from high-strength steel and uses technology similar to that proven in Cat wheel tractor-scrapers.
    •     
  • A three-stage, high-speed, double-acting cylinder is specifically designed for horizontal mounting and smooth load ejection.

LONG TERM VALUE AND DURABILITY

        
  • All structures and components are proven through extensive testing and customer experience.
    •     
  • Advanced suspension allows for greater speed over rough terrain, while softening impact loads.
    •     
  • Front suspension oscillates ±6 degrees for a smooth ride.
    •     
  • Frames are designed to handle torque loads, decrease hitch area stress, and optimize suspension geometry.
    •     
  • Frames are robot-welded for maximum durability.
    •     
  • Directional shift protection protects the powertrain when quickly moving from reverse to forward or forward to reverse.

ACHIEVE GREATER PRODUCTIVITY

        
  • Advanced Automatic Traction Control (AATC) decreases wheel slippage, delivering maximum traction and productivity. Fully automatic, no operator action.
    •     
  • Automatic Retarder Control (ARC) manages the retarder without any operator interaction. Fully automatic, 100% of the time.
    •     
  • Assisted Hoisting Control allows automatic ejecting of the load.
    •     
  • Combined eject/transmission lever, exclusive to Caterpillar, places multiple controls on the transmission lever, incorporates park brake, and reduces operator interaction by as much as 50%.

POWERFUL EFFICIENCY

        
  • Economy mode reduces fuel use without affecting productivity and can be engaged with a single button.
    •     
  • This machine design improves fuel economy with minimized maintenance costs and the same great power and response.
    •     
  • Advanced Mechanically-Actuated Electronically Controlled Unit Injection (MEUI)™-C injector platforms deliver increased injection pressures and more precise fuel rates.

WORK IN COMFORT

        
  • Tilt and telescopic steering column designed for operator comfort and control. This adjustable column allows drivers to fine-tune the steering wheel position for optimal ergonomics, especially during long shifts or rough terrain operations.
    •     
  • Simple, intuitive control and display layouts allow the operator to focus on safe machine operation, while maintaining productivity.
    •     
  • Spacious cab with seats positioned for optimal operator and trainer visibility.

TECHNOLOGY THAT GETS WORK DONE

        
  • Integrated systems give you the ability to make timely, fact-based decisions to maximize efficiency, improve productivity, and lower costs.
    •     
  • Product Link™ system connects to each machine wirelessly, allowing you to monitor location, hours, fuel use, productivity, idle time, and diagnostic codes.
    •     
  • Improved payload technology allows operators to view real-time load weights on the integrated display. Updated software and sensors provide accurate data.
    •     
  • External payload indicator lights alert the loader when to stop, reducing the risk of machine overloading.
    •     
  • Stability Assist software reports information via online VisionLink™, increasing awareness of machine history if a rollover has occurred.

BUILT-IN SAFETY FEATURES

        
  • Unique safety feature Dynamic Roll Protection supports rollover prevention and works in parallel with the already successful Cat Detect with Stability Assist, reducing downtime and safety repairs from machine rollover events.
    •     
  • Operator-presence detection system applies parking brake if gear is engaged and operator is not seated.
    •     
  • In-cab tertiary switch allows operator to bring the machine to a safe stop in the unlikely event of both main and secondary brake circuits failing.
    •     
  • Hill Assist reduces potential rollback on grades.
    •     
  • Auto Wait Brake applies the service brakes when neutral is selected and button is pressed, allowing quick and easy control of the machine while dumping and loading.
    •     
  • Ground-level fuel fill tank.
    •     
  • Integrated payload lights [when Cat Payload Monitoring (CPM) option is fitted] with wide angle beam lights on all cab roof corners provide clear visibility to loading tool operator and site controllers.
    •     
  • Secondary steering activates automatically if low pressure is sensed in primary system.

LOWER MAINTENANCE COSTS

        
  • Durable design and easier servicing mean maximized uptime and reduced service costs.
    •     
  • Universal joints are lubricated for life, eliminating any greasing during the product lifetime.
    •     
  • Coolant formula improves component life by reducing corrosion.
    •     
  • Entire machine is designed for greater ease of maintenance with side-tilting cab, electrically raised hood, access panels, and data connector.
    •     
  • Extended service intervals for the engine and transmission: 1,000 and 2,000 hours, respectively. Doubled from previous models and resulting in lower total cost of ownership.
    •     
  • Durable flexi fender reduces the risk of permanent damages and reduces repair costs.
