The Challenge

The customer tested a high performance 44.5m³ bucket fitted with the ESCO Nemisys N5 cast lip. Although the bucket had a similar capacity to its predecessor, a significant drop in fill factor was noticed, creating a miss match in truck pass matching, which in turn impacted production.

The Solution

CR collaborated with the customer, using data from the existing
Titan 3330™ payload monitoring system, CR was able to confirm that a CR N2188 (SR7043) Stingray cast lip system in a standard 45m³ bucket would out perform the previous lip system in a high production bucket.

The Impact

By using both Stingray and Titan, the customer was able to prove consistent production improvements which in turn enabled site to confidently convert their entire fleet of excavators to Stingray cast lip systems.

  • 6% higher payload
