M318 Lower maintenance costs

LOWER MAINTENANCE COSTS

  • Quickly check and service your machine with daily maintenance points accessible from ground level.
  • Check the engine oil level quickly and safely from the ground.
  • Save up to 10 percent in maintenance parts with the new, longer lasting filters.
  • Track your machine's filter life and maintenance intervals on the in-cab monitor.
  • Two levels of fuel filtration protect the engine from dirty diesel.
  • The new hydraulic oil filter provides improved filtration performance, anti-drain valves to keep oil clean when the filter is replaced, and longer life with a 3,000-hour replacement interval - 50 percent longer than previous filter designs.
  • S-O-S SM ports are located at ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.

SIMPLE TO OPERATE

  • Start the engine with the push-to-start button, a Bluetooth key fob, or the unique operator ID function.
  • Program your power mode and joystick preferences using operator ID; the excavator remembers your settings each time you go to work.
  • Navigate quickly on the standard high-resolution 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? Simply access the operator's manual on the touchscreen monitor.
  • The auto axle lock presses the pedal for you to reduce your overall number of actions. The machine automatically detects when the service brake and axle need to be locked or unlocked. It releases automatically when you press the travel pedal.

M318 Simple to operate
M318 Safely home every day

SAFELY HOME EVERY DAY

  • Access daily maintenance points from ground level.
  • Keep your excavator secure with operator ID. Use your PIN code on the monitor to enable the push-button starting feature.
  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  • Enjoy better visibility into trenches, in each swing direction and behind you, with the help of smaller cab pillars, larger windows, and a flat engine hood design. Rearview and sideview cameras are standard.
  • The service platform design provides easy, safe, and quick access to the upper service platform; the service platform steps use antiskid punch plate to prevent slipping.
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  • Travel and swing lock prevent front linkage from moving as you travel.
  • Ground level shutoff switch stops all fuel to the engine when activated and shuts down the machine.

Boost Efficiency and Productivity with Integrated Cat Technologies

  • Boost productivity versus traditional grading with optional Cat Grade with 2D system.
  • Optional Cat Payload on-board weighing system: Achieve precise load targets and increase loading efficiency with on-the-go weighing and real-time estimates of your payload without swinging.
  • Combine Payload with VisionLink® and remotely manage your production targets or take payload data with you. The monitor's USB port lets you download your results from one shift all the way up to 30 days of work so can manage your progress without needing an internet connection or VisionLink subscription.
  • Upgrade to optional Cat Grade with Advanced 2D: Create and edit grade designs with ease on a second high-resolution 254 mm (10 in) touchscreen monitor.
  • Upgrade to optional Cat Grade with 3D: Create and edit designs with ease and see the front linkage's full range of motion on a second high-resolution touchscreen monitor.
  • Optional 2D E-fence is integrated right out of the factory to prevent the excavator from moving outside operator defined set points.
  • All Cat Grade systems are compatible with radios and base stations from Trimble, Topcon, and Leica. Already invested in a grade infrastructure? You can install grade systems from Trimble, Topcon, and Leica onto the machine.

SUSTAINABILITY

  • The Cat® C4.4 engine meets U.S. EPA Tier 4 Final, EU Stage V, and Korea Tier 5 emission standards.
  • The M318 emits up to 10% less CO2 than the M318F.*
  • 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.
  • Match the excavator to the job using power modes including ECO mode that reduces engine speed and hydraulic power for applications not requiring full hydraulic power - helping you to save fuel and greenhouse gas emissions.
  • Cat Grade technologies combine advanced guidance with optional automated machine control helping you reach grading targets while helping to reduce fuel burn and greenhouse gas emissions by improving efficiency, job site productivity, and accuracy.
  • Cat® Payload for excavators provides on-the-go material weighing which helps reduce fuel burn by improving loading efficiency, job site productivity, and eliminating trips to the scale.
  • Cat 2D E-fence keeps the front linkage within a predefined work area to avoid hazards such as traffic - not only helping keep personnel safe but also helps you avoid repairs, downtime, and costly job site fines.
  • Don't waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions. VisionLink® displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
  • Extended maintenance intervals not only reduce downtime but can decrease the amount of fluid and filters that are replaced over the life of the machine. The hydraulic oil filter can now be replaced every 3000 hours - 50% longer than previous designs.
  • Remote Flash helps to minimize 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 helps to decrease maintenance time and keep 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.
*All comparisons to M318F. Productivity, fuel and CO2 emissions vary by application. CO2 emissions calculations based on a reference work cycle using 2.2 U.S. gallons per hour of #2 U.S. diesel fuel based. Applies IPCC2006 methodology using U.S. EPA Emissions Hub emission factors. Includes DEF (diesel exhaust fluid) related CO2. Fuel measurements are at 15°C. Estimated average fuel consumption improvements are based on tests or Product Link® data where available. Productivity improvements are based on test data.
**Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
