Hunter Valley, NSW
Medium Impact/Medium Abrasion
Make & Model
A prominent Hunter Valley Coal mine wanted to trial new Ground Engaging Tools with the aim of improving their excavator performance by optimising digging productivity and penetration profiles. CR Mining worked with the Mine operator to provide the solution.
CR Mining’s experienced field technicians and engineers, worked with the Mine operator to review the abrasion conditions and existing maintenance downtime schedules.
By combining this with existing GET product performance data, CR Mining was able to recommend and then successfully trial the Super Penetrator (SP) Boxpoint GET product range which would deliver better performance in the conditions.
As part of the trial, CR Mining used data from the CR Digital Titan monitoring system which was already fitted to the excavator, to deliver real-time performance metrics on payload accuracy, operator variability and fleet efficiency with the new G.E.T. setup.
The TRS7031-RA Boxpoints were run for a 13 week period setting the baseline performance for the machine. TRS7030-SP Boxpoints were then run for an 18 week period on the same R996 machine utilising the same bucket in similar digging conditions for best comparable results.

Average Fill per Tooth Type
Trucks Loaded per hour per Tooth Type
With CR Mining expert advice and the optimized Boxpoint GET, the Mine operator achieved outstanding productivity performance results including an increase on average of one truckload every hour.
The unique proprietary GET design maintained existing weight targets whilst ensuring the ground engagement profile would be optimized throughout service life.
- Achieved an additional 12-13 truck moves per day based on increased average production hours over the trial periods.
- Reduced truck fill time by an average of up to 7 seconds.
- Increased truck payloads by an average of up to 2.4%.
- Optimized material distribution for optimal wear characteristics in a backhoe application.
- Increased GET wear life, reducing machine downtime
- Self-sharpening GET features delivered more effective penetration profiles results in the coal application.
