  • 10-inch high-definition color touchscreen display that includes troubleshooting aids and machine documentation.

RELIABILITY & DURABILITY

  • Better wear of undercarriage components thanks to floating push tube, which delivers even idler slide wear and extended component life; low wear drive system via induction hardened and high quantity of sprocket teeth; and optional rough terrain undercarriage protection kit.
  • Cat exclusive Positive Pin Retention 2 (PPR2) Track design, which resists pin walking and link cracking for reliable sealing and maximum track life.
  • Structures designed and fabricated to withstand the toughest digging conditions, with high-strength steel; full penetration, profiled and ground welds at critical junctures; and booms and sticks that are stress-relieved after welding.
  • Efficient Independent Oil Cooling system, which protects and extends the life of hydraulic components.

PRODUCTIVITY & PERFORMANCE

  • Up to 25% greater efficiency through Hydraulic Optimization, which dynamically assigns individual pumps or groups of pumps to deliver the exact flow and pressure that each hydraulic function requires.
  • Durable Cat C32 engine, which offers unsurpassed performance, high power output and proven reliability, and has been proven to withstand the challenging conditions found at mine sites across the globe.
  • Engine optimized for low fuel consumption at 1,800 rpm and lower speeds, plus significant gains in fuel consumption through collaboration of engine and machine integration.
  • Maximum uptime, without work interruption for regeneration, engine derate, or cold weather treatment of secondary fluid.

BUCKETS & GET

  • Buckets and ground engaging tools (GET) designed to maximize durability and productivity and ideally matched to your shovel and application.
  • Integrated to work as part of a machine system — helping you achieve high productivity and the lowest cost per ton.
  • Variety of sizes and wear packages for the ideal match to your shovel and application.
  • Four tip shapes of hammerless GET designed specifically for the 6020B, with no special tools required for removal and installation.
  • Wear packages that protect your investment, including special liner material and lip shrouds, wing shrouds and heel shrouds.

CONNECTIVITY & TECHNOLOGY

  • Greater connectivity with improved Product Link™ Elite system, which increases the availability of data provided by the 6020B and allows it to collect and transmit information into locally hosted or cloud-hosted applications such as Cat MineStar™ Solutions Health Office, Health Equipment Insights, or Equipment Care Advisor.
  • Earliest possible detection of faults, with Board Control System that uses sensors throughout the machine to monitor operating data, record faults, and notify the operator audibly and visually.
  • Factory-ready for Cat MineStar™ Solutions, with a range of capabilities that meet the needs of your fleet.

SERVICEABILITY

  • Modular design that facilitates quick field assembly — as few as 14 days in typical condition.
  • Exchangeable power module that can be quickly swapped out for a spare, then transported for repair in a safe, convenient and clean environment.
  • Exceptional component accessibility and weather protection via first-in-class and spacious walk-through power module.
  • Superior swing system component accessibility via boom-mounted hydraulic valve block, and ground-level accessible service fluid fill points and jump start receptacle.
  • Simplified undercarriage serviceability, with automatic track tensioning system, which requires no manual adjustment; externally serviceable break; and PPR2 Tracks that are easily serviced with a master joint.

SUSTAINABILITY

  • Highly regulated C32 engine certified to meet U.S. EPA Tier 4 Final/EU Stage V emissions standards without the need for DEF — saving time and cost during maintenance.
  • Sound-suppressed power module to keep spectator sound levels low.
  • Preservation of raw materials, energy conservation and reduced emissions through the Cat Reman and Cat Rebuild programs, which return end-of-life components to like-new condition.
