Freightliner Trucks introduced the Coronado Severe Duty at the International Construction and Utility Equipment Exposition. Coronado SD is a severe-duty version of the Coronado highway tractor with a beefed-up cab, hood and other components designed specifically for hauling heavy loads on- and off-highway.
The Coronado SD, which will replace the FLD-SD that goes out of production in a few months, is a traditionally styled Class 8 model that can be ordered with big-bore Detroit and Cummins diesels rated up to 600 horsepower, forward- or setback steer axles rated up to 20,000 pounds, rear tandems up to 70,000 pounds, and lift axles rated at up to 20,000 pounds.
The reinforced fiberglass hood features impact-resistant fender edges, a stainless steel grille and projector-beam headlamps that use common, easily replaceable bulbs. Dual chrome steel intakes feed intake air to a single air filter under the hood. Optional pre-cleaners create a vortex effect to spin dust and heavy water particles out of the air before it reaches the filter. Combined dust holding capacity is equal to or better than traditional twin external cleaners.
The cab consists of an outer door frame and belt rail made from aluminum and combined with a steel inner reinforcement, resulting in sturdiness and light weight. It opens 70 degrees for easy entry and exit. Doors and windows are sealed tightly against noise and moisture.
Detroit Diesel’s DD13, DD15 and DD16 and Cummins’ ISX meet the upcoming EPA 2010 exhaust emissions standards. Detroit Diesel engines are equipped with BlueTec exhaust aftertreatment equipment that deliver a fuel economy improvement of up to 5 percent compared to EPA 2007 engines. The truck also can be equipped with the Detroit Diesel BlueTec 1-Box(tm) configuration, which combines the diesel oxidation catalyst, diesel particulate filter and SCR catalyst into one component.
