Doosan DL450 Wheel Loader
April 3, 2012

With an operating weight of 56,329 pounds, breakout force of 52,864 pounds and a full-turn tipping capacity of 41,667 pounds, the Doosan DL450 wheel loader is designed for larger material handling applications, such as quarries, mines, demolition and industrial operations. The DL450 horsepower has been increased to 354 with a 6-cylinder water-cooled diesel engine that has been optimized for use with selective catalyst reduction (SCR) and diesel exhaust fluid (DEF) to comply with iT4 emission regulations. Engines with this configuration are optimized to reduce particulate matter (PM) by operating at higher combustion temperatures and to reduce nitrogen oxides (NOX) with exhaust after treatment using SCR technology. Additionally, SCR systems offer increased fuel efficiency — as much as 16 percent on this machine —  due to the engine optimization, which improves fuel burn.
