In the demanding environment of quarry, efficiency and productivity are paramount. The choice of equipment and wear parts can significantly impact operational effectiveness and the bottom line. This case study explores the improvements achieved by upgrading the wear parts on a CAT390 excavator to the C-REX® R70AE0 teeth in Quarry.

The challenge

Previously, the wear parts on the CAT390 required replacement after 110 hours of use.

The solution

By switching to the C-REX® R70AE teeth, the replacement interval extended to 276 hours. This represents 151% extended wear life.


Machine: CAT390
