Unique in the field of self-loading concrete mixers, this very compact, agile and economical machine guarantees a yield of 4.0 m³ of concrete in every batch and a daily productivity of up to 95 to 105 m³. The DB 400 mixers are used as an alternative to small and medium batching plants. However, they have an advantage of extreme mobility, flexibility and autonomy. By equipping the DB 400 with the computerized (optional) FBC control system for concrete production process, it is possible to obtain the production of certified high quality concrete. Constancy, repeatability, and quality of the concrete batch are the unrivalled advantages of the FBC technology, exclusive to the FIORI GROUP’s self-loading concrete mixers.
