Hendrickson says it trimmed 90 pounds from its Paralift lift axle system with the production launch of the Paralift PST. Fitting Paralift with a new axle, Hendrickson says it retained the rugged durability and versatility of the 20,000-pound steerable lift axle system, while improving driveline clearance and wheel cut. The PST, which comes with a Westport axle and D22 spindle, is available for a wide variety of Class 8 truck chassis.
To enhance driveline clearance and extend wheel cut to 25 degrees, the company redesigned the axle seats and moved the stabilizers inside the tie rod and connected them to the axle brackets. Hendrickson says PST also retains features of previous Paralift models, including adjustability of frame width and ride height, allowing fleets, aftermarket installers and body builders to apply one unit to meet a wide variety of truck configurations.
The parallelogram design helps facilitate proper wheel tracking and helps keep lift plates parallel for longer air spring life. Paralift’s trailing arm beams feature a single-paddle z-beam configuration. Paralift PST delivers 12 inches of total travel with nine inches of lift in ride heights from 9.5 to 13.5 inches in a 28-inch package space. Zero-torsion trailing-arm bushings help eliminate bushing windup and allow for the two lift-spring configuration.
