Hendrickson’s Newest Has Fewer Parts, Less Weight

Hendrickson
The lightest suspension in class, weighing in at just 570 pounds including axle brackets, Hendrickson HTB suspension saves up to 257 lb over industry-standard 40,000-lb suspensions. By comparison, HTB is 250 lb lighter than the company’s HAS 400 model. The weight saving is attributed to HTB’s optimized parallelogram design that eliminates leaf springs and reduces components.

The parallelogram geometry eliminates frame rise that is characteristic of trailing-arm suspensions, aiding in the maintenance of driveline angles throughout axle travel, minimizing suspension induced driveline vibration and wear on driveline components like the transmission, differential and U-joints.

Large, direct-acting air springs carry 100 per cent of the vertical load compared to trailing-arm suspensions where vertical load is shared between air springs and leaf springs. This key difference provides up to a 34-per cent-ride improvement and reduces vibration and harshness, compared to industry-standard suspensions, says Hendrickson.
