The Challenge
The customer tested a high-performance 44.5m3 bucket fitted with a competitor’s lip. Although similar capacity as the previous bucket, a significant drop in fill factor created a miss-match in truck pass matching, which in turn impacted production.
The Solution
CR collaborated with the customer and using data from the existing Titan 3330™ Load Haul Optimization Technology, was able to confirm that a CR Stingray cast lip system in a standard 45m³ bucket would outperform the previous lip system in a high production bucket.
The Impact
The utilization of two CR Productivity Technologies together allowed the customer to prove consistent production improvements which in turn enabled the site to confidently convert their entire fleet to CR Stingray Cast Lip systems.
- 6% Increase in Payload
- 5% Dig Energy Reduction
- Standard Bucket
- Comparable Cycle Time
