LATEST FEATURES
- Cat Payload helps you achieve precise load targets to improve your operating efficiency. Pick up a load of material--with a bucket and thumb combination or grapple and clamshell attachments--and get a real-time weight estimate without swinging.
- New optional auxiliary relay powers on and turns off CB radios, beacon lights, and other attachments without you taking your hands off the joysticks.
- Remote Flash and Remote Troubleshoot now standard.
Job Matched Performance
- The Cat C7.1 engine matches your performance and production needs.
- Up to 5 percent lower fuel consumption compared to M322F.
- Built-in fuel savers like Auto Engine Speed Control and Engine Idle Shutdown eliminate waste.
- Dedicated swing pump allows faster, smoother combined movements.
- Save time with Excavator Tilt Rotator Systems that help you maneuver around obstacles without repositioning the machine
Unmatched Versatility
- Travel easily between jobsites with travel speeds up to 30 km/h (19 mph).
- Joystick buttons/sliders can be set up as desired by the operator.
- Enhanced swing lock makes it possible to lock swing and front linkage independently. Don't let the temperature stop you from working. The excavator has a standard high-ambient temperature capability of 52°C (125°F) and cold start capability of -18°C (0°F).
Easy Operation
- Start the engine with the push-to-start button, a Bluetooth key fob, or the unique Operator ID function.
- Everything can be adjusted in the cab from the steering column height to the electrically adjustable mirrors.
- Large split-screen monitor to allow quick view of multiple cameras on the same display.
- 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 inch) touchscreen monitor or with the aid of the jog dial control.
- The auto axle lock presses the pedal for you to reduce your overall number of actions. It also detects when the service brake and axle need to be locked or unlocked.
Come Home Safely
- The service platform design provides easy, safe, and quick access to the cab; the steps use an anti-skid punch plate to prevent slipping.
- Operator works in clean air thanks to the cabin filtration system that includes precleaner, a recirculation filter, and a cabin pressure monitor.
- Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
- For a clearer view of the jobsite, whether during the day or in the dark, the M322 has large glass areas, rear/side cameras, and LED lamps for all working lights.

Simplified Machine Maintenance
- Quickly check and service your machine with all daily maintenance points accessible from ground level.
- Up to 5 percent lower maintenance costs vs. previous model with the same productivity.
- Track your machine's filter life and maintenance intervals on the in-cab monitor.
- 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.
- Two levels of fuel filtration protect the engine from fuel contamination.
- Scheduled Oil Sampling (S-O-S SM) ports are located at ground level, simplifying maintenance and allowing for quick, easy extraction of fluid samples for analysis.
Elevate Business with Cat Technology
- Cat Equipment Management connects owners to their equipment, providing access to machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes.
- Remote Troubleshoot connects you to a dealer service pro to help solve your problem and quickly get you to work.
- Remote Flash works around your schedule to ensure your machine's software is up to date for optimal performance.
- Improve your operation's efficiency and productivity with integrated technologies like Grade, e-Fence, and Payload.
- Select your target depth and slope, then watch the Grade with 2D system use onboard processors and sensors to provide real-time guidance on the distance to grade.
- Cat Grade with Advanced 2D delivers real-time bucket tip elevation guidance. It also allows you to input and edit grade designs easily from the operator's seat.
- Standard 2D e-Fence prevents your machine from moving outside operator-defined parameters.
- Cat Grade with 3D works with GPS and GLONASS systems to know your machine's exact location and ensure you dig to plan.
- All Cat Grade systems are compatible with radios and base stations from Trimble.
- Already invested in a grade infrastructure? You can install grade systems from Trimble.
- Cat Payload shares what got loaded where, how much went on each truck or in the hopper, and where it went from there. It also keeps track of this over time to help operators get the right load on board, the first time, every time.

Note (2)
¹Cat 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 (hydrotreated 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. * 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.
