Pöttinger has introduced a new, contactless, electronic steered axle system on its Jumbo loader wagon that significantly improves operating and driving comfort as well as the reliability of the steering system.
Developed with ME Mobil Elektronik, the system does away with the mechanical steering angle sensor between the tractor and loader wagon. And there are no extra demands on the tractor, such as an additional K50 ball hitch for attaching a mechanical steering rod.
Available from August 2022, the steering signal is determined using a special high-resolution sensor, so there’s no need to install a mechanical steering rod to transmit the angle of articulation between the tractor and the wagon. This means that the loader wagon can be used without restriction on any vehicle, regardless of the type of hitch, or whether it’s fitted with equipment for attaching a steering rod.
There’s no need for any maintenance work or adjustments to adapt the wagon to different tractors. In addition, a tighter steering angle is possible between the tractor and loader wagon because the tractor tyre can no longer collide with the steering rod. The risk of damage is therefore eliminated.
The electronic control system also makes it possible to adapt the steering performance perfectly to different driving speeds and operating situations. Different steering strategies can be used, or the axles can be locked in the straight-ahead position. The new electronic, contactless steered axle system will be available for both tandem and tridem loader wagons.
