13 Tonne Excavators for Sale in South Australia

13 tonne excavators are the most popular mid-size class in Australia, sitting in the 10,000-16,000 kg operating weight range. They're the standard choice for commercial civil contractors running bulk trench work, stormwater infrastructure, road construction, and subdivision earthworks. Dig depths of 5.5-6.5 metres and bucket capacities around 0.5-0.7 cubic metres make them efficient on jobs where machines smaller than this would be too slow and machines larger would be overkill. Popular models include the Caterpillar 313 and 315, Komatsu PC138, Hitachi ZX130, Kobelco SK135, Hyundai R145, and Volvo EC140. Most 13 tonne machines come with steel tracks, enclosed cabs with premium air-conditioning, and hydraulic flow sufficient for rock breakers, mulchers, rotating hitches, and vibratory compactors. Transport requirements are substantial — these machines need a dedicated plant truck or float trailer, not a drag-on trailer. Used pricing typically runs from $80,000 to $180,000 depending on hours, brand, and attachment package. For contractors scaling up from 8 tonne machines, the 13 tonne class represents a major efficiency jump on bulk earthworks.
