MUSKEGON, Mich. — SAF-Holland has introduced a new Auto-PosiLift axle lift system as an option on its SAF CBX40 tandem axle slider suspension.

The system combines CBX PosiLift components with Meritor Wabco’s ABS with unique built-in functionality, the company announced. A sensor in the system’s air spring supply line reads air spring pressure and determines whether to automatically raise the front axle or leave it in the lowered position.

The system was initially designed for multi-stop beverage distribution fleets, but SAF-Holland found other varying load fleet operations such as LTL, which return to base empty, could also achieve significant fuel savings, reduced tire wear and lower toll charges.

In many fleet operations, the load over the course of a day diminishes to a point where the total weight capacity of a closed tandem axle suspension is no longer required to carry the load, allowing the front axle of the tandem to be raised, the company says. This could account for as much as 70% of a fleet’s daily miles in some applications. Running these miles with the front axle raised greatly increases efficiency and component life.

“The integration of proven Auto-PosiLifttechnology on our highly competitive and industry leading SAF CBX40 slider suspensions is a major step forward in providing our varying load fleet customers with a unique systems solutions that not only enhances the competitive position of their operation, but offers additional driver safety and convenience features,” said Randy Flanagan, director of sales and marketing, SAF-Holland Trailer Systems.
