Ongoing lagoon maintenance is relying on the 60 tonne CAT 345 long reach in removing heavy sediments washed down from the quarry processing plant. The large volume of material is being moved in 40t ADTs and requires the high productivity of the CAT 345 fitted with a 1.5m3 bucket. Wide (LGP) tracks minimise the ground pressure placed on the lagoon sides to satisfy the safety criteria for lagoon operations.
