Hendrickson extends Intraax to self-steer applications

Hendrickson
Hendrickson says its new lightweight Intraax Steerable, liftable trailer suspension system, delivers all of the benefits of Hendrickson’s road-proven integrated system and compact Under Beam Lift mechanism in a configuration that satisfies the new regulations in Ontario and Quebec for infrastructure-friendly vehicles.

Scheduled to launch production this summer, the new Steerable automatically locks when traveling in reverse, and automatically load equalizing with Intraax top-mount and low-ride/liftable non-steer systems in capacities from 23,000 to 30,000 pounds. The design of the steering dampers and reverse lock mechanism eliminates welding to the axle between the trailing arms — a common cause of axle failure in the industry. Intraax also features a ten-year / one-million-mile limited warranty on the axle / trailing arm connection.

Steerable comes in ride heights from nine to 19 inches with axle lifts from 4.3 to 5.6 inches. The system features a leading kingpin design and fits standard trailer frame widths. It provides a 20-degree wheel cut with typical 22.5-inch tires and a design that allows the use of spring brake chambers.

Employing Hendrickson’s system integration, the Steerable delivers a package that weighs up to 74 pounds per axle lighter than comparable suspension and lift axle configurations, the company says. With very few moving parts and no metal-on-metal wear zones, the UBL, weighing less than 60 pounds, requires no additional trailer support structure and provides a low maintenance package.
