High productivity machine with small dimensions, therefore suitable for large jobs with unsurpassed agility and stability. This is due to the four-wheel drive, articulated frame and differential swiveling axle. The DB180 ensures yield of 1.8 m³ in every batch. The DB 180 enables production of high quality concrete at any urban site or a remote inaccessible site. It is an economic & user-friendly machine with high productivity rating. This makes it ideal for rental and maintenance works in inaccessible areas.
