Advantages and Features

Latest Features

Machine Setup Simplification
        
  • At the touch of fingertips and navigating user-friendly icons, the latest operator oriented User Interface (UI) maximizes uptime and gets crews to work without delay. From re-ordering work tool lists to creating new work tool combinations as needed, operators can quickly set up machines and easily access information.
    •     
  • The interface allows operators to maintain accuracy and makes the most of every second of their shift. Adding the ability to input couplers and attachments into the system makes setting up work tool combinations highly efficient by significantly reducing calibration time. It also eliminates the need to measure up again when changing Cat® work tool attachments and makes it manageable for a single person to check and adjust for bucket wear.

Cat Payload and Advanced Payload*     
        
  • Cat Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Advanced Payload is a system upgrade that offers expanded features and capabilities, including custom tags, daily totals, and electronic ticketing. Combine Payload with VisionLink™** to analyze jobsites and individual assets for remote management of production targets and key metrics.

*Payload technologies are not legal for trade.
**VisionLink subscription required. 

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area. Build Number: 08D.

High Performance with Low Fuel Consumption

        
  • High fuel efficiency ensures more work per unit of fuel.
    •     
  • The C13 engine and electrohydraulic system will power through all different types of material.
