Portal axles
Unimog U 4000 / U 5000

Portal axles

Extraordinary ground clearance.

Axles with the portal design give the Unimog U 4000/U 5000 its extraordinary ground clearance. This enables it to conquer even very rough terrain and obstacles up to a height of half a metre. Reduction on the hub drive means that the full torque takes effect on the ground - for increased traction on difficult terrain.

Advantages at a glance.

  • The axle tube and differential are significantly smaller than on lorries and are positioned over the wheel centre
  • Differentials that are positioned away from the wheel centre guarantee high ground clearance even on rutted paths
