As wide as an airliner, but now lighter than ever. When a Hardi Evrard self-propelled sprayer runs across a field, it does so without damaging the crops. With a width of about 30 metres, these vast machines resemble giant birds with outstretched wings as their long, lattice booms extend freely out at the sides.
Hardi Evrard has used an advanced high strength steel for the design of its strong, resilient chassis, which is now 500 kg lighter than if it had been made of a standard steel. Additionally, the use of high strength steel in the new design enables it to better withstand very high fatigue stresses in the long spray booms created when the sprayer is travelling.
Hardi Evrard uses laser cutting and riveting, which also contributes to the improved properties.
Read more about the high stresses that they create are carried by an advanced chassis manufacturered from high strength steel. The structure is light but stable, reliable and durable.
