Dossan introduced two new articulated dump trucks for the 28- and 40-metric-ton class – DA30-50 and DA40-5.
The 365 hp DA30-5 and 490 hp DA40-5 are powered by Scania DC9 and DC13 diesel engines.
The trucks have been configured with a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR). Tier 4 compliant Doosan ADTs combine selective catalyst reduction (SCR) with a diesel oxidation catalyst (DOC) to reduce engine emission levels.
The trucks offer a variety of driveline improvements, like the DA40-5 has a new bolt-on rear differential and new gear ratios.
DA30-5 and DA40-5 have an external engine to keep the engine cool and prevent over-pressurization.
