Autocar returns to concrete with mixer, pump chassis series

Previewed earlier this month at the National Ready Mixed Concrete Association’s ConcreteWorks conference, the Autocar DC-64M and DC-64P models for mixer and pump operators share a conventional truck platform engineered from the ground up for severe duty. Autocar Trucks has worked with a pilot group of ready mixed producers on the DC-64M concept and plans formal Q1 unveiling of a full mixer package, timed with World of Concrete and ConExpo-Con/Agg 2020 in Las Vegas.

Autocar arrived at ConcreteWorks 2019 with one of the first DC-64 chassis to roll off its Alabama assembly line. The premier model carries a 112-in. bumper-to-back-of-cab spec with axle set back just shy of 50 inches and overall 232-in. wheelbase.

“The DC models are the result of extensive input from our advisory board of concrete professionals,” says Managing Director Eric Schwartz. “Every inch of these trucks has been reviewed and improved based on the decades of experience of people operating concrete mixer and boom pump trucks.

“The DC-64M incorporates a raft of improvements and features specific to concrete mixer trucks, such as rear-engine power takeoffs and asymmetrical self-leveling front suspensions. And every DC-64P will be custom-engineered for the specific pump body the pumper selects. Suspensions and multiple steer, drive, and auxiliary axles will all be selected and placed for optimal weight distribution and maneuverability.”

The DC cab is designed for exceptional safety, productivity and durability in concrete delivery and placing operations, Schwartz adds. It combines steel, judiciously chosen aluminum components, and corner castings to withstand years of abuse ready mixed plant and concrete construction sites dish out. The DC-64M and DC-64P and sister Autocar models for refuse and terminal markets are the first Class 8 trucks to feature ultra-high-strength, 160,000 psi steel frame rails—24 percent stronger and lighter than conventional heavy-duty model members and capable of eliminating the need for frame liners in nearly all mixer applications.

The inaugural DC powertrain runs Cummins X12 engines in 380- to 500-hp and 1,700 lb-ft of torque ratings, coupled with Allison RDS4500 and 4700 series automatic transmissions for maximum torque at low speeds and easy drivability on-road or at tricky construction sites. Autocar Trucks has booked DC models for Spring 2020 delivery, scheduling assembly at its Birmingham plant.  —  Autocar Trucks, 877/973-3486; www.AutocarTruck.com/my-new-truck
