All new design features below grade operation, low overall height and narrow stabilizer spread.

April 23, 2009 - Appleton, WI – Pierce Manufacturing, an Oshkosh Corporation (NYSE:OSK) company, today unveiled the all new 100-foot aluminum aerial platform and basket on display in Indianapolis at the Fire Department Instructors Conference (FDIC) at booth #9404. The versatile Pierce^® 100-foot aluminum aerial features best-in-class performance in a small overall footprint that includes an impressive 11-foot 9-inch overall height and a compact 15-foot 6-inch stabilizer spread with 18-inches of ground penetration.

The aerial is rated for 1,000 lbs dry tip-load and at 500 lbs while flowing up to 2,000 gallons-per-minute. It features an operating range from -11.5º to +76º angle with a 235º rotation at -11.5º. The below grade operation allows for a low step height to the basket without having to extend the device, providing for more versatile operation in tight quarters.

“Firefighter safety and mobility were key factors in the development of the all new Pierce 100-foot aluminum platform. The combination of low overall height, an ergonomic basket and excellent performance numbers will help make this Pierce aerial an instant category leader,” said Wilson Jones, Oshkosh Corporation executive vice president and president, Fire & Emergency. “Our job is to provide the tools and advanced technologies firefighters need to be more effective and efficient, and we set a very high bar with this aerial. For departments who prefer aluminum over steel, they no longer have to settle for anything less than a Pierce.”

Constructed with a beautiful swirl finish, the three-section aluminum ladder achieves a 2:1 safety factor and 1.5:1 stability factor for a full measure of confidence. The unit can perform in 35-mph wind conditions and when covered in one-quarter inch of ice. Stunning LED lighting - in a department’s choice of red, blue, green or white - is available for all ladder sections.

The hydraulics and wiring are engineered into the ladder sides to allow for an open walkway for firefighters. The side-mounted waterway design is protected from rooflines and other obstructions.

The all-new aluminum basket was engineered after exhaustive research and ergonomic study. It features angled doors, single or dual monitors, 8-inch walkways on each side and moveable controls with three connecting positions. The unique auto-leveling basket manually adjusts up or down 10° out of level with override controls at the platform and the turntable for more firefighter control. The basket is also able to utilize the entire family of Lyfeline™ accessories for specific rescue operations.

Pump system options include the Pierce Ultimate Configuration (PUC), which maximizes space utilization by removing the bulky pumphouse without compromising firefighting capabilities.

The Pierce 100-foot aluminum aerial platform features a 20-year warranty on the aerial structure, a 10-year body warranty and five years for the hydraulic components and Command Zone™ electronics.
