In September, Hendrickson International will release a 20,000-pound-capacity version of its ComposiLite SC steerable lift axle for vocational trucks and trailers.

Earlier this year it released 10,000- and 13,000-pound models while announcing the new product series.

ComposiLite SC reduces weight, minimizes package space and offers the industry the first flexible tie-rod and dampened lift axle design, said Mike Gottschalk, general manager of Hendrickson Auxiliary Axle Systems. The product offers increased payload and reduced maintenance, while continuing to provide Hendrickson's recognized product performance and durability.

It uses a patent-pending Compliant Tie Rod, a flexible steel member that bends upon hitting roadway obstructions but springs back into shape so the axle, and truck, can keep going. A robust self-centering mechanism returns wheels to straight-ahead position and improves the driver's feel of the road.

Along with the ComposiLite SC launch for the Class 8 truck market, Hendrickson will offer a complete line of trailer-mount steerable products, also in multiple capacity configurations, Gottschalk said. Each is covered by a three-year warranty package.
