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® Grade 3D Ready
        
  • The Cat Grade 3D Ready option includes all the hardware required for the Grade with 3D system, installed and tested from the factory. This option provides an easier upgrade path for customers who want to add Grade with 3D after their initial purchase. To activate, contact your Cat Dealer to purchase the required 3D software licenses. Licenses can be installed remotely or manually loaded onto the machine.

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® Productivity** 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: 07H

Cat 320 Hydraulic Excavator - DESIGNED FOR OPERATORS

Simple to Operate

        
  • Start the engine with a push button; use a Bluetooth® key fob, or the Operator ID passcode.
  •     
  • Program each joystick button, including response and pattern, using Operator ID; the machine will remember what you set each time you go to work.
  •     
  • Program up to four depth and slope offsets so you can easily get to grade without a grade checker – a real time saver and safety enhancer on the jobsite.
  •     
  • Navigate quickly on the standard high-resolution 203 mm (8in) touchscreen monitor, or with the optional 254 mm (10 in) touchscreen monitor, or with the aid of the jog dial control.
  •     
  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
  •     
  • Continuously improved user interface allows for intuitive navigation, minimizing performance interruption with the easy-to-use touchscreen menu.
  •     
  • Use the in-monitor QR code to learn about machine and technology features through a full suite of “how-to” videos.
  •     
  • Protect your hammer tool from overheating and rapid wear. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds - all to extend the tool’s service life.
  •     
  • The Cat® PL161 attachment locator is a Bluetooth device designed to let users know where their attachments are across all worksites, reduce the number of lost attachments, and plan for attachment maintenance and replacement. The PL161 integrates easily into VisionLink® for full fleet management of machines and attachments from one smartphone or tablet dashboard to view location and tracking details.
  •     
  • Save more time and energy with the available work tool recognition feature. A simple shake of the attached tool confirms its identity and ensures all the attachment settings (pressure, flow, and dimensions) are correct so you can work quickly and efficiently.*
  •     
  • Auto Dig Boost increases power by up to 8% for better bucket penetration, shorter cycle times, and greater payloads.**
  •     
  • Need more lift during your shift? Turn on Auto Heavy Lift and get up to 8% more power exactly when you need it for as long as you need it.**
  •     
  • Make moving the excavator much easier with Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers or pedals.
  •     
  • Make operating easier with the touch of a joystick button. Additional auxiliary relays allow you to power on or turn off a CB radio, beacon light, and even a dust suppression watering system without taking your hands off the joysticks (Deluxe cab only).

*Automated attachment settings must be enabled within each machine configuration. Consult your Cat dealer for details.
**Auto Dig Boost and Auto Heavy Lift calculations are based on 380 bar (boost pressure) divided by 350 bar (standard pressure). Does not apply to long reach excavators.

  •     
  • The standard ROPS cab meets ISO 12117-2 2008 requirements.
  •     
  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab pillars, larger windows, and a flat engine hood design.
  •     
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  •     
  • Ground level shut-off switch stops all fuel to the engine when activated and shuts down the machine.
  •     
  • A rearview camera is standard. Upgrade to 360° visibility and you'll see objects and personnel around the excavator in a single view.
  •     
  • Right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platform steps use anti-skid punch plate to prevent slipping. The handrails comply with ISO 2867:2011 requirements.
  •     
  • Make service work easier with optional inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.
  •     
  • Enhance jobsite safety. Add a swing alarm to alert people when you're rotating from trench to stockpile and back again.

*The system may not detect personnel in certain circumstances, such as fast swing speeds, people lying down or crouching, or when cameras are impaired by low light conditions (dusk, dawn, overcast), inclement weather (snow, rain, fog), or other similar conditions. For limitations of use, refer to the operation and maintenance manual.
**Operator assist features for the Command Console are not available in Australia and New Zealand.
