After two years of procedure, the Spanish Patent Office grants ROJO Trailer the invention protection for the next ten years. (Registration number: ES 1 259 166 U)

This AluHARD 500 exclusive chassis, which is equal in weight to the aluminium ones but with 300% more resistance, fits important innovations:

1. Made entirely of exceptional extra-elastic steel.
2. It is reduced the welding of the main beams by 50%. This is very important, because the welds are always the weakest parts of the structures.
3. The welding is replaced by cold pleats. Without the contribution of the welding heat processes, which modifies the exceptional qualities of this steel.
4. The upper shape of the chassis “hugs” the tipper body. It improves the rigidity of the group when it is driving and it reduces its centre of gravity.
5. The new rounded shapes, without corners in the chassis, increases its bending strength by 40% compared to our 2014 AluHARD 450 model. Since it eliminates stress concentration points.
6. The new electrical installation, with a high IP rating, ensures the reliability of the electronic and security systems for many years. Even in extreme environments.
