The 122SD is the ultimate work truck: powerful, rugged and versatile. These heavy commercial trucks can haul anything from granite to logs to heavy equipment with ease — across severe terrain, down a mountain and around hairpin curves. As a leading heavy truck manufacture, we've designed the 122SD to be dependable, comfortable and profitable. These heavy commercial trucks can take you and your business to new heights.

PERFORMANCE

The 122SD doesn't just look great, it takes performance to another level. It packs the horsepower, torque and efficiency needed for demanding jobs and an impressive bottom line. 

With the 122SD, you get to choose between two of the most respected engine brands in the world. All three of Detroit's flagship engines—the DD16®, DD15® and DD13®—are available, along with the Cummins ISX15. Whichever engine you choose, you'll have a package designed for outstanding fuel efficiency—with up to 600 horsepower (DD16 and ISX15) and up to 2050 lb-ft torque @1100 rpm.
 

Handles Extreme Loads

The 122SD also features a wheel cut up to 50-degrees that helps negotiate tight spaces. And with steer axles rated from 12,000 to 22,000 lbs., drive axles rated from 23,000 to 70,000 lbs, and an industry leading 1,900 square inch radiator to cool engines up to 600hp/2050lbft. torque with loads up to 160,000 lbs. GCW, you get the performance to haul all your heavy loads through rough terrain. Choosing our TufTrac® rear axle suspension provides maximum traction in high articulation environments. A wide variety of rear axle configurations/suspensions are available, even tag and pusher axles, with liftable and steerable options, available with ratings up to 22,000 to carry your biggest loads. There’s no doubt: the 122SD is ready to take on anything, any day.

Handles Extreme Roads

Some roads can be rough, and unpaved job sites can be treacherous. That's why every 122SD is built with "pillow-block" front cab mounts designed to dampen shock and vibration. The rear cab mounts use air springs spaced apart to give the truck a wide stance for great stability. This ensures you get a good feel for the road. And to help keep drivers safe in dangerous work conditions, the 122SD cab meets or exceeds the rigorous Swedish and European ECE R-29 crash-worthiness requirements.

Ready for 2010 and Beyond

Every engine available in the 122SD is designed to use the proven selective catalytic reduction (SCR) to meet the EPA 2010 mandate. The built-in SCR system brings your NOx and particulate matter down to acceptable levels. And operating the SCR-equipped truck is simple. Just monitor the single DEF/fuel gauge. And when it's time to refill, nationwide DEF distribution is in place to make it easy. With a DD13 or DD15 BlueTec® SCR engine under the hood, you can achieve up to 5% better fuel economy compared to a similarly spec’d DD13 or DD15 '07 engine.

Clean Technology for Severe Environments

The three-stage intake system on the 122SD truck combats airborne dust and dirt—even on the harshest job sites. Air enters through the dual air intakes and is sent into the hood air plenum, with optional pre-cleaners, where most of the moisture is removed. A bellows then directs the clean and dry air through the new Donaldson® Advanced PowerCore® Air Filter before directing it into the engine. This single filter holds more dirt than dual air filters. It's also long lasting, hard working and easily changeable.

Control the Power

With a wide range of Eaton and Allison transmissions, you can choose the drive you want, and the power you need. You also have the option of adding a transmission power take-off (PTO) so you can get the job done once you get to the worksite.
 

You've Got Pull

When you need your tow hooks, you really need them. Whether you get a set-forward or set-back axle, the 122SD has the tow hooks to get you out of a jam, and meet Truck Maintenance Council guidelines. The optional 3/8" steel logger bumper gives the added strength of a heavy-duty center tow pin that provides 80,000 lbs of towing capacity.

DURABILITY

The 122SD is built to be a tough-as-nails workhorse because we know that uptime is king and the average truck can't take the kind of abuse that a harsh environment can dole out.

Strong Features

The solid engineering of the 122SD is designed to handle whatever’s thrown at it. With frame and wheelbase configurations suited to your specific application, this truck can take on just about anything. It also features:

• A durable, proven non-corrosive aluminum cab

• Strong proven cab construction; Henrob rivets used throughout the cab, and coach joints at cab roof and sidewall connections

• State-of-the-art adhesives to bond the cab's substructure to distribute forces and decrease fatigue

• Bonded windshields to increase rigidity and the 2-piece design makes them easier to replace when damaged

• Chrome- plated steel front grill surround, with stainless steel grill

• Single-piece fiberglass hood

• Chrome-plated aluminum hood handle that's built to last

• Standard steel grille opening reinforcements to provide extra strength

• An HVAC unit designed to thrive in harsh environments. Plus easy access under the dash to make repairs a breeze

• Reinforced doors designed to last as long as the truck

• Updated dash with fewer sections for quiet, durable service

Put to the Test

The 122SD is tough. Test after test proves it. The components, systems and entire truck has been subjected to an array of virtual and physical tests to ensure the 122SD delivers the expected function, performance and reliability. The result is a durable and safe cab that meets stringent A-pillar impact, rollover and back wall impact tests. Plus, the vocational chassis includes a robust backbone with a complete offering of single and double channel frame rails. This provides a tensile strength of up to 120,000 psi and an RBM ratio up to 5 million inch-pounds per rail. So it can handle the abuse of a typical job site, no problem. 

STYLE AND COMFORT

The 122SD is your quiet, comfortable, all-day workplace. We designed a comfortable and spacious working environment on the inside, because you never know how harsh it will be outside.

In Control.

The 122SD dashboard is command central with ivory-colored gauges and a dash structure designed with fewer sections, making it one of our quietest and most durable. 
 

Rugged Cab to Handle Anything

Wide and roomy cab. Solid, tightly sealed doors. And large, single-piece HVAC registers to cool you down during those long, hot days on the job.

Keep Everything in Reach

Your truck is your workspace on wheels, so we designed 122SD to make your day-to-day work just a little easier. The easy-access cup holder and storage area hold your daily essentials. The most frequently used controls and switches are located within easy reach, and LED backlights make reading gauges a breeze, reducing eyestrain even in the darkest of nights.
