Although the miner was running the latest fleet management systems (FMS), there were a high number of truck overloads each day, causing a bottleneck in production.
The excavator operators lacked confidence in weights reported by the truck payload system due to the variable accuracy and latency, so they weren’t targeting high-capacity loads.
The challenge was to provide an accurate real-time payload management system so operators could increase average truck payloads and maximize productivity without increasing overloads.
The Titan 3330 payload management system was installed on the miner’s fleet of Liebherr backhoes.
Titan 3330 provides real-time, pass-by-pass feedback to operators, enabling accurate truck loading while minimizing truck overloads. Sensors fitted on the excavator identify individual bucket cycles and truck payloads. A running summary of each truck and bucket payload is reported live on the Titan 3330 screen.
Operator training on the Titan 3330 system was rolled out once the product was installed and commissioned. CR Digital provided data reporting tools to the customer to monitor the impact of the system.
