  • 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.

Not all features are available in all regions. Please check with your local Cat dealer for specific offering availability in your area. Build Number: 07C


  • Use up to 10% less fuel versus the previous model, with no impact on your productivity.
  • The C4.4 engine can run on biodiesel up to B20 and meets US EPA Tier 4 Final and EU Stage V Final emissions standards with an aftertreatment system that requires no maintenance or downtime.
  • The advanced electro-hydraulic system provides the optimum balance of power and efficiency while giving you the control you need.
  • Valve priority puts hydraulic pressure and flow where you need it.
  • Boost lifting capabilities and improve the controllability of heavy loads with heavy lift mode.
  • Program your preferred power mode and joystick settings using your operator ID. The machine will automatically remember your selections
  • Available SmartBoom™ lets the boom freely travel up and down without using any pump flow so operators can focus on stick and bucket work.
  • The Cat App helps you manage fleet location, hours, and maintenance schedules; it also alerts you for required maintenance and even allows you to request service from your local Cat dealer.
  • Product Link comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand.


  • Match your machine to your application. Multiple configurations allow you to customize your machine to your needs.
  • Equip your MH3022 with an optional 15kW generator for magnet operation. Generator controls are fully integrated into the cab monitor.
  • Expand your work capabilities with attachments for a variety of applications.


  • Choose between Deluxe and Premium cab options.
  • The Deluxe seat is heated and air adjustable, while the Premium seat is heated and ventilated and adjusts automatically.
  • The cab has a wide seat that adjusts for operators of all sizes.
  • Control the machine comfortably with easy-to-reach controls.
  • Standard automatic climate control keeps you at the right temperature all shift long.
  • Stow your gear with plenty of in-cab storage beneath and behind the seat, overhead, and in the consoles. A cup holder, document holder, bottle holder, and coat hook are also provided.
  • Use the standard radio's USB ports and Bluetooth® technology to connect to personal devices.


  • Count on your machine to withstand wear throughout the years. Boom, sticks, and other high-stress areas are reinforced with thick multi-plate fabrications, castings, and forgings to ensure quality and reliability.
  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  • Don't let the temperature stop you from working. The material handler has a standard high-ambient temperature capability of 52° C (125° F) and cold start capability of -18° C (-0°F
  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.


  • Cab Avoidance helps you avoid contact between your worktool and the cab.
  • Standard E-Fence prevents your machine from moving outside operator-defined parameters.
  • Keep your machine secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
  • Access 100 percent of daily maintenance points from ground level -no need for you to climb on top of the excavator.
  • Enjoy all-around great visibility with the help of smaller cab pillars, larger windows, and a flat engine hood design. Rearview and sideview cameras are standard along with optional 360-degree visibility system.
  • Thicker high impact and impact resistant windshields fulfil respectively the EN356 P8B and P5A standards.
  • A cab pre-filtration package reduces dust entry and air contamination.
  • Joystick steering eliminates steering column, improving front visibility and increasing cab entrance width. There is an option for a steering wheel for operators who prefer it.
  • New right service platform design provides easy, safe, and quick access to the upper service platform; the service platform steps use anti-skid punch plate to prevent slipping.
  • The standard hydraulic lockout lever isolates all hydraulic and travel functions in the lowered position.
  • Optional Falling Object Guard System (FOGS) provides protection from falling and flying debris.
  • Ground-level shutoff switch stops all fuel to the engine when activated and shuts down the machine.
  • Boom and stick lowering check valves prevent reverse flow, keeping your front linkage securely in place should the hydraulic system unexpectedly lose power.


  • Track your machine's filter life and maintenance intervals via the in-cab monitor.
  • Change all fuel filters at a synchronized 1,000 hours.
  • Expect the new air intake filter with precleaner to last up to 1,000 hours.
  • 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.
  • High-efficiency, electrically driven cooling fans run only when needed; you can program intervals, so they automatically reverse to keep cores clean without interrupting your work.
  • S·O·SSM ports simplify maintenance and allowing for quick, easy extraction of fluid samples for analysis.
