Hunter Valley, Australia
Make & Model
An Australian mining contractor operating in New South Wales commissioned a new ultra class mining excavator. A short time into the excavator’s life, signs of overutilization began to emerge. Although the asset was achieving excellent production rates, the Miner had no way of quantifying and monitoring machine attachment duty. The challenge was placed to record and report duty to both maintenance and production teams, provide a method of self-regulation for operators and subsequently reduce overall machine duty.
CR Digital’s experienced field technicians worked with the Miner to install the Titan 3330 Load Haul Optimization system on the Liebherr R9800 backhoe. The duty monitoring system is specifically designed to minimize machine duty by providing real-time, pass-by-pass feedback to operators on the major attachments through hydraulic cylinder monitoring.
Sensors fitted on the excavator identify bucket cycles and map hydraulic circuit loads at high frequencies. A duty summary of each individual bucket cycle is reported live on the Titan 3330 user interface.
Operator training on the intuitive Titan 3330 system was rolled out once the product was installed and commissioned. Data reporting tools were provided to the customer to observe the impact of the system.
High Duty Factors indicate elevated loads on the excavator attachments and accelerated consumption of machine life.
