Auto-PosiLift axle lift technology is now an option on SAF CBX40 Tandem Axle Slider Suspension systems. The Auto-PosiLift combines SAF-Holland CBX PosiLift axle lift feature with an electronic control unit and air valve system on a tandem slider suspension to provide an automated axle lift function.
Developed initially for multi-stop beverage distribution fleets and other varying load operations, the Auto-PosiLift is programmed to read air pressure in the rear axle air springs each time a delivery or pick-up is made. Without driver interaction, the system determines whether to automatically raise or lower the front axle in a trailer tandem as the load changes.
When total weight carrying capacity of a closed tandem axle suspension is no longer required to carry the load, SAF-Holland notes, operating with the tandem suspension with the front axle raised increases fuel efficiency, tire life, suspension component life and brake and wheel-end service intervals.
