Overview

If you want a machine with the power to match your jobs but owning and operating costs to fit your business, then the Cat® 311F L RR excavator is your answer. Its reduced radius will get you into some pretty tight spots, and its reasonable price and miserly fuel burn will help you operate on a tight budget.

Features

MOVE MORE WITH LESS FUEL

  • 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.

EXPAND YOUR CAPABILITIES

  • 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.

DESIGNED FOR OPERATORS

  • 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.

BUILT TO PERFORM

  • 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.

SAVE ON SERVICE AND 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.

ENSURING A SAFE JOB SITE

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

    * Regulation requirement for Europe only.

EFFICIENCY THROUGH TECHNOLOGY

  • Cat technology improves job site efficiency.
  • Product Link™ system connects owners to their equipment, providing access to machine data such as location, hours, fuel consumption, idle time, events, and diagnostic codes.
