Daimler Trucks North America has announced that the Freightliner 122SD severe-duty truck model can now be spec’d with Allison 4700 Rugged Duty Series (RDS) and Oil Field Series (OFS) automatic transmissions.
According to the OEM, the combination of the 122SD with Allison’s vocational transmissions is ideal for tough off-road and oil field applications. “Better performance comes from such features as 2nd Reverse, which offers a second ‘deep reverse’ in addition to the standard reverse; automatic shifts, which automatically and smoothly make the right shift at the right time; and greater startablity, which uses less torque to launch and go.”
Both automatic transmissions are available on trucks powered by Detroit DD13, DD15 and DD16 and Cummins ISX heavy-duty engines.
“Our severe-duty customers have demanding jobs that require powerful, heavy-duty solutions that won’t compromise productivity,” said Mary Aufdemberg, director of product marketing for Freightliner Trucks. “Allison’s specialized transmissions meet those exacting requirements and, when paired with the 122SD, provide a smart solution for extreme jobs.”
In addition to the new transmission options, under-the-passenger-seat battery mounting is now available for all 122SD day and sleeper cab configurations. This option provides additional space for body builders by freeing up valuable rail space.
The heavy duty model of the Freightliner severe duty line of vocational trucks, the 122SD is suitable for oversize hauling, specialty hauling, oil/gas field service, construction, towing/recovery and vocational on-highway applications.
