PERFORMANCE WITH LESS FUEL

  • The excavator uses up to 20 percent less fuel than the 320F in similar applications.
  • Match the excavator to the job with power modes; let Smart mode automatically match engine and hydraulic power to digging conditions.
  • The advanced hydraulic system provides the optimum balance of power and efficiency while giving you the control you need for precise digging requirements.
  • Valve priority puts hydraulic pressure and flow where you command it to go for fast lightto medium load cycle times.
  • The engine meets U.S. EPA Tier 4 Final and EU Stage IV emission standards with an aftertreatment system that requires no operator input or downtime.
  • Add auxiliary hydraulics to do more work with a range of Cat attachments.
  • Product Link™ comes standard so you can remotely monitor machine health, location, hours, and fuel consumption on demand through the VisionLink® online interface.

LOWER MAINTENANCE COSTS

  • Expect up to 25percent less maintenance cost than the 320E (savings calculated over 12,000 machine hours).
  • Do all daily maintenance at ground level.
  • Check engine oil level quickly and safely with the new ground level engine oil dipstick; fill and check engine oil on top of the machine with a conveniently located second dipstick.
  • Track your excavator’s filter life and maintenance intervals via the in-cab monitor.
  • No required maintenance on the Cat Clean Emissions Module.
  • Using Cat genuine oil and filters and doing your typical S∙O∙S monitoring will double the current service interval to 1,000 hours, giving you greater uptime to do more work.
  • 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.
  • The new high-efficiency electric cooling fans only run when needed and reverse to keep cores free from debris.
  • S·O·S ports simplify maintenance and allow for quick, easy extraction of samples for fluid analysis.

RELIABILITY YOU CAN COUNT ON

  • Work up to 3000 m (9,840 ft) above sea level without de-rating.
  • Standard high-ambient temperature capability is 52º C (125º F) with cold start capability at –32º C (–25º F).
  • Auto warm up speeds up hydraulic oil warming in cold temperatures and helps prolong the life of components.
  • Three levels of fuel filtration protect the engine from dirty diesel fuel.
  • Grease sealed between track pins and bushings reduces travel noise and prevents debris from entering to increase undercarriage life.
  • The center track guiding guard helps keep the excavator track aligned when traveling and working on slopes.
  • The sloped track frame prevents mud and debris accumulation, helping reduce risk of track damage.

SAFELY HOME EVERY DAY

  • Access 100 percent of daily maintenance points from ground level – no need for you to climb on top of the excavator.
  • Keep your excavator secure with Operator ID. Use your PIN code on the monitor to enable the pushbutton starting feature.
  • The standard ROPS cab meets ISO 12117-2:2008 requirements.
  • Enjoy great visibility into the trench, in each swing direction, and behind you with the help of smaller cab posts and larger windows.
  • A rearview camera is standard, and a right-side-view camera is optional.
  • The new right-hand service platform design provides easy, safe, and quick access to upper service platform; the service platformsteps use anti-skid punch plate to prevent slipping.
  • The handrails comply with ISO 2867:2011 requirements.
  • The lower frame meets ISO 15818:2017 lifting and tie-down requirements.

SIMPLE TO OPERATE

  • Start the engine with a push button; use a Bluetooth key fob, smartphone app, or the unique Operator ID function.
  • Program each joystick button, including response and pattern, using Operator ID; it will also remember climate control fan and radio settings.
  • Navigate quickly on the standard high-resolution 203 mm (8 in) touchscreen monitor or with the aid of the jog dial control.
  • Protect your hammer from overworking. Auto hammer stop warns you after 15 seconds of continuous firing and then automatically shuts it off after 30 seconds -- all to prevent wear and tear on the attachment and excavator.
  • Not sure how a function works or how to maintain the excavator? Always have the operator’s manual at your fingertips in the touchscreen monitor.
  • The Cat PL161 Attachment Locator is a Bluetooth device that makes finding your attachments and other gear quick and easy. The Cat App on your phone will locate the device automatically.
