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*
          
    • Cat Payload provides operators with on-the-go weighing to help them hit load targets and avoid overloading, underloading, or misloading materials. Combine Payload with VisionLinkTM** to analyze jobsites and individual assets for remote management of production targets and key metrics.

    Swing Assist
          
    • Swing Assist automatically stops machine swing at operator-defined preset points. Simply swing to the desired stopping point and activate using the machine monitor or a preset joystick button. As you get closer, the machine will automatically decelerate and not allow swing past the set point. Swing Assist helps you hit more repetitive swing targets to help reduce fuel use and improve cycle times.

    *Payload technologies are not legal for trade.
    **VisionLinkTM 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: 07E

High Performance

          
    • The C7.1 engine can run on biodiesel up to B20 and meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 and Korea Tier 4 Final emission standards with an aftertreatment system that requires no maintenance or downtime.
      •     
    • Match the machine to the job with three power modes - Power, Smart, and Eco. Smart mode automatically matches engine and hydraulic power to working conditions, helping provide maximum power when needed and reducing power when it isn't to save fuel.
      •     
    • The advanced electro-hydraulic system helps provide the optimum balance of power and efficiency while giving you the control you need.
      •     
    • Available SmartBoom™ lets the boom freely travel up and down without using any pump flow so operators can focus on stick and bucket work.
      •     
    • Valve priority helps put hydraulic pressure and flow where you need it.
      •     
    • Program and store your preferred power mode and joystick settings using your Operator ID. The machine will automatically remember your selections.

Integrated Cat® Technologies

          
    • Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material – with a grapple or clamshell attachment – and get a real-time weight estimate without swinging.
      •     
    • VisionLinkTM provides actionable data insights for all assets - regardless of fleet size or equipment manufacturer. *Review equipment data from your desktop or mobile device to maximize uptime and optimize assets. Dashboards provide information such as hours, miles, location, idle time, and fuel utilization. Make informed decisions that lower costs, simplify maintenance, and improve safety and security on your jobsite.
      •     
    • Swing Assist automatically stops machine swing at operator-defined preset points. Simply swing to the desired stopping point and activate using the machine monitor or a preset joystick button. As you get closer, the machine will automatically decelerate and not allow swing past the set point.

      •     
    • Remote Troubleshoot is a mobile application that allows your Cat dealer to perform diagnostic testing on your connected machine remotely to help ensure that issues are resolved quickly and with less downtime.
      •     
    • Remote Flash is a mobile application that allows you to update onboard software without a technician being present, allowing you to initiate software updates when convenient, increasing your overall operating efficiency.
