  • Operator Coaching is an in-cab system that recognizes specific opportunities for operators to be more productive and prevent unnecessary machine wear and tear.  

Take The Guesswork Out of Managing Your Equipment

  
        
  • ​VisionLink® 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.​
    •     
  • VisionLink® Productivity gathers and summarizes machine telematics and jobsite data from all your equipment – regardless of the manufacture.* View actionable information such as idle time, fuel burn, location, payload, load counts, total cycles, and more to improve machine efficiency, productivity, and utilization. Access data anywhere via a mobile, tablet, or desktop device - on or off the jobsite.​
    •     
  • Cat® Inspect is a mobile application that allows you to easily perform digital preventative maintenance (PM) checks, inspections, and daily walkarounds. Inspections can easily be integrated with other Cat data systems like VisionLink® so you can keep a close eye on your fleet.​

High Performance, Low Fuel Consumption

 
        
  • Powerful digging force and strong swing torque enable the use of large buckets up to 3.2 m3 (4.2 yd3) for class-leading productivity.
    •     
  • Compared to the Cat 349-07, the 350 consumes up to 13 percent less fuel for lower operating costs and greater profit potential.
    •     
  • Match the excavator to the job with three power modes – Smart, Power, and Eco. Smart mode automatically matches engine and hydraulic power to digging conditions, providing maximum power when needed and reducing power when it isn’t to help save fuel. Power mode is maximum power all the time. Eco mode reduces engine speed and keeps it constant to reduce fuel consumption.
    •     
  • Valve priority puts hydraulic pressure and flow where you command it to go for fast light- to medium-load cycle times.

Simple To Operate

 
        
  • Start the engine with a push button; use a Bluetooth key fob or Operator ID passcode. 
    •     
  • Program each joystick button – including power mode, response, and pattern – using Operator ID; the machine will remember what you set each time you go to work.
    •     
  • Trouble cutting through tough material? Auto dig boost gives you an automatic power increase of 8 percent when you need it for better bucket penetration, shorter cycle times, and greater payloads.
    •     
  • Need more lift during your shift? Auto heavy lift gives you 8 percent more power exactly when you need it for as long as you need it.
    •     
  • Make moving the excavator much easier with optional Cat Stick Steer. Simply push a button and use one hand to travel and turn instead of both hands or feet on levers and pedals.
    •     
  • Cat continues to improve user interface functionality for operators of all skill levels. The touchscreen monitor is an easy-to-use operating tool that presents the jobsite dashboard with an intuitive format. Productivity applications are displayed in grid-view to read on-the-go, and touchscreen navigation is programmed to make sure job performance continues without any hold ups.
    •     
  • Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds – all to prevent wear and tear on the attachment and excavator.
    •     
  • 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.
    •     
  • 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.

    •     
  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
    •     
  • Make service work easier and safer with inspection lighting. With the flip of a switch, lights will illuminate the engine, pump, battery, and radiator compartments to enhance visibility.
    •     
  • Serrated steps and anti-skid punch plate on the service platform help prevent slipping.
    •     
  • Add an optional swing alarm to safeguard surroundings and assets. This feature sends out warnings to the operator for any unexpected swings to enhance safety, minimizing downtime and increasing productivity.
    •     
  • A rearview camera is standard.
    •     
  • The Rollover Protective Structure (ROPS) cab meets industry standards and protects the operator in the event of a rollover.

Easy Maintenance

Sustainability

        
  • The Cat® C7.1 TTA engine meets U.S. EPA Tier 4 Final, EU Stage V, and Japan 2014 emission standards.
    •     
  • Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
    •     
  • Cat Grade technologies combine advanced guidance with optional automated machine control helping you reach grading targets while reducing fuel burn and greenhouse gas emissions by improving efficiency, job site productivity, and accuracy.

    •     
  • Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine.
    •     
  • Cat VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the runtime fuel burned each day in a selected date range.
    •     
  • Remote Flash minimizes downtime and maintenance time while keeping your asset running with maximum efficiency. Alerts for machine updates are sent virtually from your Cat dealer and updates can be deployed without a dealer technician needing to be onsite.
    •     
  • Remote Troubleshoot decreases maintenance time and keeps your machine running with maximum efficiency by allowing your Cat dealer to virtually test the machine while working. Once a problem is identified, a technician can fix it the first time, saving time and money.

*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel  (for use of blends higher than 20% biodiesel, consult your Cat dealer).
**Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
