Freightliner Trucks launched its new 122SD at the 2013 Mid-America Trucking Show. Formerly the Coronado SD but now with many enhancements, it features rugged components and is the cornerstone of the SD line of severe-duty vocational trucks.
With a GVWR of up to 92,000 lb and a GCWR up to 160,000 lb, the 122SD can be configured for a variety of severe-duty applications like logging, oil/gas field services, concrete mixing, specialty/heavy-haul, crane, dump, vocational on-highway, and towing/recovery.
The 122SD has a non-corrosive aluminum SD cab reinforced with e-coated steel, and Freightliner says it meets stringent A-pillar impact, rollover, and back-wall impact tests. “State-of-the-art” adhesives and Henrob rivets reinforce the cab’s structure. The chassis features a broad offering of vocational suspension choices and single- or double-channel frame rails with tensile strength of up to 120,000 psi and up to 5 million RBM.
Additional new standard and optional components found on the 122SD include hood durability enhancements; west-coast-style door-mounted mirrors; severe-duty front cab mounts; impact-resistant back window; a lower radiator rock guard and an up to 1700-sq-in. radiator; durable halogen headlights with replaceable glass lens reflectors; one-piece skid plate; logger front bumper rated to 80,000 lb; disc brakes; and an in-cab battery box for the daycab.
The 122SD comes equipped with the OBD13 certified/GHG14-compliant Detroit DD15 TC engine, which features an ideal combination of torque and horsepower for heavy-duty applications. Detroit DD13, DD16, and Cummins ISX15 engines — with ratings up to 600 hp and 2050 lb ft of torque — can also be spec’d.
The truck is available with a variety of Eaton manual and automated manual transmissions, including the optional Eaton Cobra shifter, as well as Allison automatic transmission options.
