At the beginning of the year, the German truck mixer manufacturer Intermix launched a lightweight concrete mixer with both the concrete drum and the inner spiral made out of 3 millimeter Hardox steel plate. The new mixer already makes up 60 percent of the company’s sales.
“Compared to the 4.5 millimeter standard steel that we used before, the lightweight version reduces the weight of the structure by as much as 18 percent,” says Harald Schmidt, sales director at Intermix. “The most important part is that Hardox is so wear-resistant that the lifetime of the truck mixer stays the same even with reduced steel thickness.”
Intermix is one of Europe’s leading manufacturers of truck mixers. It wanted to optimize the payload of its vehicles as concrete is heavy at 2.4 tons per cubic meter. German road regulations allow a maximum total weight of 32 tons, while an average four-axle concrete mixer weighs about 14 tons empty.
Hardox constructions have been around for a while in the field of dump trucks, but there hadn’t been any attempts to use it in a light concrete mixer. Intermix teamed up with SSAB to learn how to work with the thinner, highly wear-resistant Hardox plates. On January 16, the company got its “Hardox in My Body” (HIMB) license.
“We are proud to be the first on the world market with an HIMB concrete mixer,” says Schmidt. “Considering the huge interest we’re seeing in Germany and other countries, we expect it to sell well in a large part of the European market in the near future.”
Intermix will exhibit the new truck mixer at INTERMAT in Paris on April 16-21.
