Truck mixers are used every day. They have to run reliably and be low-maintenance. Low wear-and-tear in particular plays an important role in a rough environment and in dealing with coarse materials, so that it can supply transport concrete without any loss in quality for years to come. Consequently, TBL steel from Thyssen-Krupp has been integrated into the Putzmeister standard truck mixer. This heat-treatable steel provides special protection against wear-and-tear at a good price-performance ratio. The truck mixer therefore withstands difficult conditions and ensures a long service life.
