20 Tonne Excavators for Sale in South Australia

20 tonne excavators are the most common large-class excavator in Australian construction and mining support, typically weighing 16,000-25,000 kg. This is the size class that dominates commercial bulk earthworks, quarry loading, large civil infrastructure, demolition, and mine site support work. Dig depths of 6.5-7.5 metres with bucket capacities of 0.9-1.3 cubic metres give the productivity needed to keep a rotation of trucks moving. Common models include the Caterpillar 320 and 323, Komatsu PC200 and PC210, Hitachi ZX200, Hyundai R210 and R220, Volvo EC220, Kobelco SK210, Sumitomo SH210, and JCB JS220. All come standard with steel tracks, heavy-duty undercarriages, and auxiliary hydraulic flow sufficient for large breakers, shears, and grapples. 20 tonne excavators require float transport — a dedicated plant truck or tilt-tray tow. Used pricing on 20 tonne machines ranges from $90,000 to $250,000 depending on hours, age, brand, and attachment package. Low-hour late-model Japanese and European brands hold value exceptionally well on the Australian resale market.
