  1. by Nemanja Miletic, Product Manager SAF-HOLLAND Australia SAF-HOLLAND Sub-assemblies in PBS

  2. About SAF-HOLLAND

  3. Sub-assemblies currently in PBS Fifth Wheels Truck Suspensions INTRA range trailer MODUL type trailer

  4. INTRA range – a bit of theory… IU - Underslung IO - Overslung • Roll stiffness – achieved through 3D-bush, air bags • and suspension design • Roll centre – cannot do much about it… • Roll steer – design compromise between roll centre height • and axle position

  5. How do we test them? US test laboratory – certified by DOTARS – Fifth wheels & truck suspensions SAF in Germany – servo-hydralic road simulator – 3 axis both sides + torque

  6. What we would like to see, or food for thoughts… • Do we need a set of recommended test procedures for different parameters as a guide? • Range of recommended values for the most common applications • More feedback from certifiers so we can improve Thank you…
