The Komatsu 930E is a 300 tonne dump truck and one of their flagship machines and a market leader, with the very nature of heavy mining creating and exacerbating fuel contamination issues due to the extent of free dirt created.
Specifically, at the Pelambres mine in Chile, the Komatsu 930E machines powered by the Cummins QSK60 2700hp engines, were unable to run fuel filters for their prescribed planned maintenance periods of 500 hours between changes. Filters were blocking prematurely causing significant disruption to operations and an increase in down-time and a huge increase in maintenance costs.
Komatsu Cummins contacted FuelActive in March 2012 ask the question of whether a potential solution could be developed where a FuelActive unit could be alleviate the problems being suffered by the Cummins QSK60 engines at Pelambres?
FuelActive designed and installed a custom HHP (High Horsepower) unit into a Komatsu 930E on the mine which went on to deliver immediate results. Fuel filters easily reached their prescribed 500 hours of use and often reached 1,000 hours.
Fuel contamination issues ceased to be a problem and the Cummins QSK60 engine operated trouble free for in excess of 30,000 hours when supplied fuel through the FuelActive pick-up unit.
Following this success FuelActive has continued to work closely with Komatsu Cummins to provide solutions to fuel contamination issues and protection of fuel filters, pumps and injectors.
