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.
