Fuel Efficiency

  • The C3.4B U.S. EPA Tier 4 Final/EU Stage IV engine burns up to 14% less fuel than the model it replaces, the 311D.
  • The engine is equipped to run on up to B20 biodiesel fuel.
  • Two power modes, high power and eco mode, help operators manage fuel consumption.
  • Auto engine idle shutdown saves fuel, reduces emissions, and extends service intervals.

Versatility

  • Reduced radius is ideal for work in space-restricted areas.
  • Site prep and finishing work are quick and easy with a wide range of Cat work tools.
  • Utility work is fast and flawless with a Cat bucket and compactor.
  • A coupler lets you swap between attachments in seconds without leaving the cab.
  • See the whole money-making attachment line for your machine at www.cat.com/attachments.

Comfort

  • The roll-over protective structure (ROPS) certified cab is quiet and comfortable.
  • Automatic climate control helps maintain consistent cab temperature.
  • Joystick consoles and armrests are adjustable.
  • Seats are adjustable and feature air suspension and heated and cooled options.
  • The LCD monitor is easy to navigate and programmable in 42 languages.

Durability

  • Booms and sticks are built with baffle plates for enhanced service life.
  • Box-section structures with multi-plate fabrications, castings, and forgings are used in high-stress areas.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.

Maintenance

  • Many routine service and maintenance points can be accessed from ground level reducing the time taken to check and service your machine.
  • Service doors are designed to prevent debris entry and to make access to fluid taps and filters easy.
  • The cooling package is designed to prevent plugging and has wide clearance to help make blowing off debris easy.

Safety

  • The side-view camera is offered to enhance visibility on the boom side of the machine to help make operators more effective and efficient.*
