EFFICIENCY AND PRODUCTIVITY

  • A powerful C4.4 electrically controlled engine meets U.S. EPA Tier 3, EU Stage IIIA equivalent and China Nonroad Stage III emission standards.
  • Two-pump hydraulic system pressure delivers terrific digging performance and productivity.
  • Hydraulic cross-sensing system uses two hydraulic pumps under all operating conditions, improving productivity with faster implement speeds and quicker, stronger pivot turns.

PERFORMANCE WITH LESS FUEL

  • Economy mode maintains breakout forces and lift capacity at standard power, balancing demands of performance and fuel economy.
  • Boom and stick regeneration circuits save energy during boom-down and stick-in operation.
  • New compact design utilizes shorter tubes and lines to reduce friction and pressure drops, resulting in more efficient use of power.

REDUCED MAINTENANCE TIME

  • The service door on the right side of the upper structure allows ground-level access to the pump, pilot filter, drain filter, and the engine oil filter.
  • Easily accessible, ground-level service locations allow quick and efficient maintenance.
  • The left service door allows easy access to the engine radiator, oil cooler, air-to-air-aftercooler, primary filter with water separator (if the two are integrated) and secondary fuel filter.
  • The radiator air filter features a double-element construction for superior cleaning efficiency; a warning is displayed on the monitor screen inside the cab when the filter plugs.

DESIGNED FOR OPERATORS

  • An adjustable seat and joystick console are designed to meet individual preferences.
  • Low-effort pilot-operated joystick controls are designed to match natural wrist and arm position for maximum comfort and minimum fatigue.
  • The full-color LCD monitor is programmable in 42 languages.
  • The cab shell is attached to frame with viscous rubber mounts to dampen vibrations and sound levels, enhancing operator comfort.

PURPOSE-BUILT CAT ATTACHMENTS

  • Site prep and finishing work are quick and easy with a Cat® grapple, thumb, and hammer.
  • 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.

BUILT TO PERFORM

  • The modified X‐frame structure provides a long service life.
  • Robot-welded and stress-relieved heavy duty boom and stick are standard.
  • Track shoes, links, rollers, idlers, and final drives are built with high‑tensile-strength steel.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.

BUILT-IN SAFETY FEATURES

  • Anti-skid plating covering the entire upper structure and storage box prevents slipping during maintenance.
  • Countersunk bolts reduce trip hazards during service and maintenance.
  • The engine radiator fan is enclosed by fine wire mesh, reducing risk of an accident.
