Features

PROVEN RELIABILITY

• Cat C15 engine delivers high performance across a variety of applications.
• Class-leading transmission technology with advanced productivity electronic control strategy (APECS) and electronic clutch pressure control (ECPC).
• Enhanced reliability through commonality and design simplicity, with long life to overhaul.
• Minimized impact of emission systems allows excellent response and power.
• Engine compression brake improves retarding response and increases retarding power for controlled descent of grades.
• Aftertreatment technologies reduce emissions, including reducing NOx emissions by 80%.

DURABILITY

• All structures and components are proven through extensive testing and customer experience.
• Suspension allows 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.
• Redesigned dump body provides reinforced top edge on side rail.

ACHIEVE GREATER PRODUCTIVITY

• High density power shift (HDPS) transmission is designed specifically for articulated trucks with nine forward/two reverse speeds and improved acceleration.
• Variable gearshift points are based on the operating conditions, reducing the use of torque converter drive and helping maintain ground speed during gear changes on grades.
• Advanced automatic traction control (AATC) decreases wheel slippage, delivering maximum traction and increased productivity.  Fully automatic with no operator action.
• Truck body dimensions and other specifications are an excellent match to Cat loaders and other loading equipment, resulting in fewer passes, increased production, and lower system costs.
• Optional body heat solution reduces carry back in specific applications.

BOOST FUEL EFFICIENCY

• Economy mode reduces fuel use without affecting productivity and can be engaged with a single button.
• Advanced Mechanical Electronic Unit Injector (MEUI™) system delivers increased injection pressures and more precise fuel rates.  These durable injectors enhance responsiveness while controlling soot.
• Innovative air-management systems optimize airflow and enhance power and fuel efficiency.
• Fully automatic retarder control helps prevent engine overspeed, preserves the machine without any operator intervention.

EASY, COMFORTABLE OPERATOR ENVIRONMENT

• Simple, intuitive control and display layouts allow operator to focus on safe machine operation, while maintaining productivity.
• Assisted hoisting control allows automatic tipping; full manual control can be selected.
• Combined hoist/transmission lever, exclusive to Caterpillar, places multiple controls on the transmission lever, incorporates park brake, and reduces operator interaction by as much as 50%.
• Standard air suspension seat designed to absorb shocks and enhance operator comfort during long shifts. For added comfort and climate control, an optional heated and cooled leather seat is available, offering multiple adjustments to suit individual preferences.
• Spacious cab with seats positioned for optimal operator and trainer visibility.
• High-performance HVAC system ensures optimal cabin temperature and air quality for operator comfort in all weather conditions. The advanced cooling system maintains ideal engine and transmission temperatures, even under heavy loads and extreme environments.
• Updated touchscreen display allows easy monitoring and adjustment of systems.
• Dedicated storage solutions for everyday items, ensuring convenience and organization, comfort and room for movement for the operator.
