Safety – Designed with Your Safety as Our Top Priority


Sharing your commitment to safety, and driven by our commitment to Zero Harm, we work tirelessly to design the safest machines possible to protect your most important asset; your employees.




Some examples of the safety-enhancing features of the Cat 6020B Hydraulic Mining Shovel include the following:

Serviceability – Service Friendly for Greater Uptime


This capability also allows for transporting of the power module away from the production area to allow service and repair in a safe, convenient, and clean environment.

Emissions Technology – Providing you reliable, integrated solutions.


The 6020B is offered with two variations of the C32 engine with ACERT Technology. One will meet Tier 4 Final emission standards and will be required for sale in higher regulated countries. The other option will emit equivalent to Tier 2 for lesser or non-regulated countries.




The 6020B meets Tier 4 Final emission standards using:
  • Cat NOx Reduction System – captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down temperatures and reduces NOx emissions.
  • Dual Diesel Oxidation Catalysts (DOCs) – use a chemical process called oxidation to condition exhaust gases to meet emission standards.
  • MEUI™-C Fuel System – delivers increased fuel efficiency, while further reducing NOx emissions. Ultra low sulfur diesel (ULSD) fuel and low ash oil are required.

The Tier 4 Final solution of the C32 ACERT engine has a maintenance free aftertreatment design, which uses the systems above to meet emissions standards. Designed to meet performance demands with lower cost of ownership, the primary advantages of this solution include:
