Excavators, loaders and dump trucks are very important machines when working in mines and quarries. Due to their intensive use, they are exposed to high loads, which is why they need to be protected with particularly resistant materials. We found this out in collaboration with a key customer. To effectively protect our customer's machines against abrasion and thus extend their service life, we recommend the use of our wear-resistant materials KALMETALL, KALCAST and KALEN. They have proven to be the ideal solution.
