The longitudinal beams of the trailer were upgraded from yield strength 310 MPa to Strenx® 700, saving 350 kg of weight, or 37%, of the upgraded parts. The total weight ofthe timber trailer could be reduced by an additional 150 kg through changes in design in other parts of the chassis. In total, the trailer´s load capacity was increased by 500 kg.
Together with our customers, SSAB continually upgrades steel and equipment designs. SSAB EcoUpgraded saves CO2 both in steel production and during the full lifetime of the machine.
From the CO2 payback time and onwards, every extra hour brings additional savings.
