30 Tonne Excavators for Sale in Queensland

30 tonne excavators are large-class production machines used almost exclusively on commercial and heavy civil projects, weighing 25,000-35,000 kg. This class sits at the productivity sweet spot for bulk cut-and-fill earthworks, major quarry operations, mine site support, and heavy civil infrastructure like highway and dam works. Dig depths of 7-8 metres with bucket capacities up to 2 cubic metres allow a 30 tonne excavator to keep 4-6 tandem tippers in continuous rotation on a well-organised site. Common models in Australia include the Caterpillar 330 and 336, Komatsu PC300, Hitachi ZX330, Hyundai R300 and R320, Volvo EC300 and EC350, Kobelco SK300, and Sumitomo SH300. These are substantial machines requiring heavy float transport, heavy-duty float trailers, and operators with genuine experience — running one efficiently is a different skill set to running a 13 or 20 tonne machine. Used pricing on 30 tonne excavators typically sits between $140,000 and $380,000 depending on hours, age, and condition. The Australian market for used 30 tonne excavators is well-established with strong demand from civil contractors and quarries.
