On vehicles with close axles, self-steering guarantees vehicle stability and improves manoeuvring.

However, being ready to follow bends is conditioned by weight, speed and type of tyres used. In particular, highly deformable, strongly adhering low pressure tyres, fitted to new farm machinery, means that self-steering reacts late so the vehicle can have difficulty re-aligning its wheels, with driving, road-holding and abnormal tread wear problems.

With the new, patented ADR self-steering axles, these problems belong to the past: steering sensitivity adapts to the wheels and resolves problems linked to low pressure tyres.

The heart of innovation is the articulation joint: new geometry and mechanical conception.

The special inclination means it uses vehicle weight and wheel diameter as “motors” to control reactions and make sure that self-steering is always “made-to-measure” for the application it is used on.

Besides innovative geometry, this exceptional sensitivity comes from new generation materials, mechanical precision and careful assembly.

The ADR self-steering range, from 7 to 16 tons per axle, makes this important technological innovation available for manufacturers of all trailer types, both agricultural and industrial.

The possibility to equip these self-steerers with all the ADR brake range makes them even more versatile and means axle and suspension groups can be made for all needs.
