The innovative and self levelling centre pivot assembly is based on 3
instead of 4 joints. From this result outstanding driving and direction
characteristics. This unique Hamm pivoted steering with the 3 ball
joints guarantees an unsurpassed directional stability and driving
comfort. Even with full steering angle the chassis construction provides
for an even weight distribution on drum and wheels and ensures in such a
way for careful absorption also with uneven terrains. Tilting with
driving along curves is also more strongly avoided.
