Hendrickson Announces Availability of 9,000-Capacity Composilite Steerable

Press release date: April 1, 2004

HEBRON, OHIO - Hendrickson unveils a 9,000-pound capacity version of COMPOSILITE ST(TM) for truck and trailer applications.

Delivering all of the advantages and durability of the 13,500-pound capacity version, the new lighter duty COMPOSILITE ST provides a superior choice for fleets and owner operators who only need to carry 9,000 pounds or less per lift axle.

Weighing only 720 pounds, COMPOSILITE ST 9K is designed for use with 19.5-inch tires. It weighs in around 930 to 963 pounds including tires and rims, depending on the tire selected.

New features include a 2.5-inch drop axle and an aluminum cross member. The shorter drop axle provides the ability to use 19.5-inch tires and the aluminum cross member helps reduce system weight. The suspension is designed with aluminum hangers; steel hangers are available as an option.

The in-line air spring design provides maximized packaging space, measuring 23.5 inches from front edge of hanger to centerline of axle. The aluminum beams remain parallel to ensure proper wheel tracking for increased tire life, while lift plates remain parallel for longer air spring life. The stabilizer uses a cover to protect the stabilizer rod from dirt and debris throughout travel.

"Hendrickson maintains key features to the end-user, including 28-degrees of wheel cut and 13.5 inches of travel, at the same time, we provide a light-duty system that allows for quick and easy maintenance." stated Paul Brown, marketing manager of Hendrickson Auxiliary Axle Systems. "All COMPOSILITE suspensions use industry standard components including 15- by 4-inch brakes. This allows replacement parts to be readily available."

Zero torsion bushings eliminate bushing windup and provide a smaller package space for a lighter weight product. This provides more consistent down force and reduced lift force resistance; therefore, only one-half the amount of force is required to operate the lift axle.
