It has long been recognised that the high stripping ratio at an open cut mine and the loading of large tonnage trucks are two of the most productive areas for improvement. The continued development of both equipment and mining methods has meant that open pit mines are able to handle these larger haul trucks, and these trucks require equally large excavators to match. As these excavators have increased in size, so too has their fuel consumption.
