Oshkosh Truck Brings Revolution(R) Composite Mixer Drum to Its Front-Discharge Concrete Mixer Line.

OSHKOSH, Wis. -- Oshkosh Truck Corporation (NYSE:OSK), announced today that its S-Series(TM) front-discharge concrete mixer truck is now available with the Revolution(R) composite mixer drum. Total weight savings compared to a similar-sized steel drum is a full 2,000 pounds, which provides an available payload unmatched by any other front discharge mixer in the industry. The vehicle currently is on display at the Oshkosh / McNeilus booth C-6869 at the World of Concrete trade show in Las Vegas.

"The Revolution composite mixer technology offers remarkable performance benefits, and we're extremely pleased to introduce it to a new segment of the concrete placement market. The S-Series front-discharge concrete mixer with a Revolution drum provides concrete producers with a serious payload advantage," said Robert G. Bohn, Oshkosh chairman, president and chief executive officer. "The 2,000 pound weight savings can mean a significant increase in productivity for our customers."

The new front-discharge Revolution drum features a smooth exterior finish that provides easy-cleaning characteristics and an ideal surface for a producer to apply graphics and decals.

First introduced in 2002, more than 1,000 Revolution drums currently are in service in rear discharge fleets. The lightweight, composite drum is certified through independent testing conducted by the respected Truck Mixer Manufacturers Bureau (TMMB).

Because the Revolution drum itself is 2,000 pounds lighter than a comparable steel drum, ready mix producers can carry an additional one-half cubic yard of concrete per load. Assuming four loads per day and 250 working days per year, the productivity gain is estimated at $7,500 annually.
