Portal Axle for city buses AVN 132

Step-free boarding in articulated buses

For articulated trolleybuses, ZF offers the non-driven portal axle. Combined with the drive portal axle, AV 133, a more accessible step-free passenger area with no raised platform is realized in the articulated trolleybus. Faster boarding and alighting of passengers and shorter stop times support higher average speeds. This means that more passengers can be transported each day.


  • Rapid, step-free entry and exit
  • Comfort for passengers
  • Quiet running
  • Floor heights of just 405 mm
  • Also available as driven portal axle AV 133
