A regular MosKomMash garbage truck had an 8 mm thick tail produced from mild steel with reinforcements on the bottom. When the economic climate changed, the company sought greater efficiency in its production and construction materials.
“During the boom days, we never thought twice about Hardox® as we focused more on mass production than on innovations, even though product improvement was always important for us,” says Chief Designer Alexander Melnik. “We’d heard about Hardox®, but it was only during the downturn when SSAB’s Moscow representative visited us that we decided to test Hardox® in our garbage trucks.”
The 8 mm thick tail was replaced in two test trucks with 5 mm thick Hardox® 450 without reinforcements. The results, Melnik says, exceeded all his expectations. The tail made of Hardox® 450 lasted three times longer than the normal tail made from mild steel, and weight and production costs were reduced since less welding was needed. The company also received welding recommendations from SSAB.
“It costs around USD 117 more to replace the mild steel with Hardox®, but I have to say that this is really nothing compared to the benefits that we, and end users, get,” Melnik says. Besides being the first company in Russia to use Hardox® for this type of application, he firmly believes that it will dramatically improve the quality and reliability of MosKomMash’s trucks.
