Oshkosh reveals next generation S-Series, electric prototype mixers

Oshkosh has evolved S-Series specs and technology features in lockstep with a broader shift in diesel-powered equipment—from mechanical to digital mind set. The next generation model premiered at the Oshkosh Convention Center gathering of front discharge mixer operators. PHOTOS: Concrete Products

In a surprise twist, Oshkosh engineers capped the S-Series Reveal event unveiling an all-electric technology demonstrator model, with 8-yd. drum and prodigious batteries replacing diesel engine and exhaust treatment. A proof of concept vehicle that has successfully executed ready mixed delivery and placement duty cycles, the S-Series SDX 300 is subject to additional engineering prior to any formal field demonstrations and production planning. The SD stands for “silent drum.”

Oshkosh assembled more than 50 ready mix producers from across the industry to unveil and open the order book for the new Oshkosh S-Series front discharge mixer truck. Measured against a legacy model introduced 25 years ago and upgraded in 1999, the new S-Series will have:

 • Better fuel economy and higher payload potential—equivalent to .25 to 1 yard, depending on state or market-specific axle specs—attributable to lighter, high performance powertrain and hydraulic power components;

• Lower maintenance requirements, reflecting simplified frame rail, reduced volume of parts throughout the vehicle, and movement of components from outer rails to less impact-prone points;

• Front and rear axle standardization, optimized around 39 states’ bridge law requirements and enabling quick 210-, 220- or 230-ft. wheelbase configurations; and,

• Driver-friendly features topped by a newly designed cab’s ergonomics, ease of ingress and egress, greater visibility, and increased storage space.

Also standard on the model will be FLEX Controls, a package of sensors monitoring key mixer functions and available in rear discharge models of sister brand McNeilus following a ConExpo-Con/Agg 2017 debut. Concurrent with the S-Series overhaul is the launch of ClearSky, an Oshkosh developed and managed telematics platform tailored to mixer truck fleets. When integrated with FLEX, ClearSky will offer ready mixed producers all-encompassing driver, customer, project, truck and fleet analytics.

The S-Series and Technology Reveal-themed unveiling was staged in early June at the Oshkosh Convention Center, near company headquarters. Oshkosh President and CEO Wilson Jones and senior engineering staff discussed the S-Series evolution in terms of an overall migration in diesel-powered equipment from mechanical to digital, Internet of Things-heavy operation. They underscored TCO, or total cost of ownership, as the driving force behind the S-Series engineering and upgraded specs.

Joining the host were representatives of lead partners on the S-Series development to discuss the role of their now-standard components: Cummins X12 engine in 380- or 430-hp ratings; Dana Corp. D46-172 rear tandem suspension; and, Kawasaki M7V variable displacement hydraulic motor. The Cummins and Dana components are key to the weight savings realized in the new versus legacy S-Series model, while the Kawasaki motor helps improve fuel efficiencies. New S-Series production will be scheduled with an eye to early-2020 deliveries.
