Technology

  • Get to grade quickly and accurately with standard Cat® Grade Control, a simple-to-use system that provides real-time bucket tip positioning and cut and fill data right through the standard cab monitor.
  • Get to grade up to 45% faster with less effort with Cat Grade with ASSIST, a system that automates work you typically do with manual controls.
  • Easily upgrade to AccuGrade™, a 3D system that will help you make perfect cuts and contours on more complex jobs.

Performance

  • Dig with maximum breakout force at all times regardless of engine speed and power mode.
  • Lift objects smoothly and controllably without time limit using the optional heavy lift function.
  • Stay productive with a smart emissions system that works without interruption.

Efficiency

  • Meets EU Stage IV emission standards with 5% less fuel consumption than the Stage IIIB C4.4 ACERT™ engine.
  • Actively manage fuel consumption in changing digging conditions using three selectable power modes.
  • Take advantage of fuel-saving flexibility with up to B20 biofuel capability.

Versatility

  • Maximize your uptime by speeding attachment changes with optional Cat couplers.
  • Get to work more quickly with Cat tool control, an exclusive system that stores pressures and flows for up to 20 attachments.
  • Expand your performance with optional auxiliary hydraulics and attachments from Cat Work Tools.

Maintenance

  • Spend less time servicing the machine with extended maintenance intervals and a maintenance-free diesel particulate filter.
  • Safely perform most routine maintenance like daily greasing and fluid taps from ground level.
  • Access service compartments through wide doors that securely latch in place.

Comfort

  • Work in quiet satisfaction with viscous mounts that limit cab vibration and special roof lining and sealing that reduce interior sound.
  • Stay content with a consistent cab temperature provided by standard automatic climate control.
  • All heated seats include a reclining back, upper and lower slide adjustments, and height and tilt angle adjustments.

Durability

  • Count on long service life with our multi-plate fabrications, castings, and forgings used in high-stress areas of the upper and lower frames.
  • Depend on long life from Cat booms and sticks with our advanced robot welding techniques and ultrasound inspection to ensure quality and reliability.
  • Rely on our undercarriage in demanding conditions with our high-tensile-strength steel track shoes, links, rollers, idlers, and final drives; water, debris, and dust are kept out because of greased track delivering even longer wear life and reduced travel noise.
