Apart from the weight savings from thinner thicknesses because of the properties and the yield strength of the material, Hardox® 450 makes it possible for dump bodies to withstand greater impacts than a box made of normal materials could withstand. “Not only does its thickness help make it lighter, it can also withstand harsher operations, and the possibility of cracking or deformation is greatly reduced," José emphasizes.
Two years ago, VOLMEX combined some parts of the equipment that were previously made of commercial steel. “The box frame - the floor, the door, the sides and the top - is made of 100% Hardox® 450 steel and now the structural elements, such as the edges and some bracing, are made of Strenx® high-strength structural steel, so they have very similar strengths," he explains. “This has proven to be a very good point, because now in the Mexican market, many dump box manufacturers using Hardox® 450 continue to mix and use commercial steels, such as ASTM-A36, in some body parts.”
"Our customers have not only noticed a substantial improvement in the useful life of the dump boxes, they now also tell us that they have considerably reduced compulsory sidelining of their equipment with tipper models made from commercial steels due to the constant cracks and deformations, achieving a noticeable increase in the efficiency of their operations with the new products.
Performance is also the manufacturer's problem. Since dump boxes made of commercial steels were produced with greater thicknesses, they required more filler material for welding. With Hardox® 450 material, Jose Luis says the team gained in internal efficiency and a cleaner design. “This means 11% time savings in production and the product has a European look - it’s quite aesthetic and that’s attractive to customers," he emphasizes.
