Retiring Excavator EX110
They say all good things must come to an end but for EX110 there is a silver lining. We retired our CAT 5230B excavator in 2021, which first arrived as a brand-new machine on site in 2002. This excavator is one of only seven of this model ever made, the first to be sent out into the world to work and the oldest machine operating in our open pit.
CAT 5230B Excavator
Over its 20-year life of operational use, EX110 has received four engine changeouts, one in-frame rebuild and at one point was split in two to replace the main slew bearing when the machine was 52,000 hours old.
