Doosan introduces its first new Tier 4 (T4)-compliant crawler excavators, the DX300LC-5 and DX350LC-5. Doosan excavators improved in four key areas: fuel efficiency, productivity, operator comfort and durability. For example, a T4-compliant DX350LC-5 crawler excavator features a 10 percent fuel savings from the equivalent Tier 3 model. D-ECOPOWER optimizes hydraulic system output with engine horsepower, improving machine efficiency, productivity and fuel consumption, as well as refines machine control enhancing operator comfort. For uptime protection, Doosan excavators have an improved track spring and idler assembly, and larger bushing in track rollers. Both models come with a standard three-year subscription to telematics.
