Performance

  • The Cat® C7.1 ACERT™ electronic engine consumes up to 11% less fuel than the model it replaces.
  • Constant engine speed control adjusts fuel pressure and hydraulic flow to maintain optimal engine speed regardless of load, maximizing productivity and reducing fuel use and noise.
  • Caterpillar built hydraulic pumps deliver superior power with increased efficiency.
  • Boom and stick regeneration reduces fuel consumption.

Versatility

  • Utility and finishing work are fast and flawless with Cat buckets, thumbs, and compactors.
  • Demolition work is quick and easy with Cat hammers, grapples, shears, and multi-processors.
  • Cat couplers let you swap between attachments in seconds without leaving the cab.
  • See the whole money-making attachment lineup at www.cat.com/attachments.

Safety

  • The hydraulic activation lever safely locks out all hydraulic functions.
  • An electric fuel priming pump speeds up starts and fuel system maintenance.
  • Anti-skid plating and countersunk bolts reduce slipping in severe conditions during routine checks.
  • A full-length firewall separates the pump compartment from the engine.
  • A ground-level fuel cutoff switch shuts down the engine in an emergency.
  • The side-view camera (Turkey and HK only) enhances visibility on the boom side of the machine to help make operators more effective and efficient.

Durability

  • The fuel system is built to be less sensitive with low-quality fuel.
  • The modified X-frame structure provides long life and durability.
  • Heavy-duty booms and sticks are built for tough work.
  • Greased track link between pins and bushings increases undercarriage life and reduces noise.

Ease of Operation

  • The ROPS cab is ergonomically designed with easy-to-operate controls.
  • Multiple seat and joystick adjustment options enhance comfort.
  • Excellent work site visibility from the cab enhances productivity and safety.
  • Optimized low-effort joystick controls reduces operator fatigue.
  • Automatic climate control with several vents maximizes comfort.

Maintenance

  • Most service locations can be accessed at ground level.
  • The number of fuel filters reduced from 4 to 3, lowering owning and operating costs.
  • Filters are grouped together to reduce maintenance time.
  • Pressure taps and S∙O∙SSM ports help maximize uptime.

Technology

  • Cat Connect technology solutions increase production and minimize operating costs.
  • Link Technologies wirelessly connect you to your job site to provide essential business information through VisionLink® and Product Link™.
