The DX530 is a 50-tonne class large tracked hydraulic excavator from Doosan (brand now DEVELON), a workhorse for mining, quarrying, heavy earthmoving and heavy lifting. Powered by a Scania DC13 engine (6-cylinder, 12.7L, ~283–294 kW / 379–394 hp @ 1800 rpm), it comes mainly in DX530LC-5, -7, -7M and -7B versions — with the LC-7 the current next-gen model (Stage V). It uses an X-chassis undercarriage for strength and stability, high lifting capacity, optional super-long reach, and one-touch power boost. Dimensions (transport): length ~11,500–11,530 mm; width ~3,300–4,200 mm; height ~3,900–4,170 mm. Operating weight typically 52.9–55.3 tonnes (DX530LC-7 ≈ 55,250 kg / 121,804 lb). Max digging depth ~7,340 mm; bucket ~3.0–3.3 m³.
