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 90/100 m³. The DB 460 mixers are used as an alternative to small and medium batching plants. However, they have an advantage of extreme mobility (accentuated by driving reversibility and the drum rotation system for 360° discharge), flexibility and autonomy. By equipping the DB 460 with the computerized (optional) CBV 2.0 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 CBV 2.0 technology, exclusive to the FIORI GROUP self-loading concrete mixers.

Features
PERFORMANCE AND HANDLING
‣ Unparalleled agility and stability; even in loaded condition due to lower center of gravity
‣ Four-wheel drive & steering
‣ Reversible driving seat & 245° drum rotation
‣ High pressure automotive hydrostatic transmission for working on any kind of terrain
CONCRETE BATCHING VEHICLE
‣ CBV version – A computerized electronic batching system ensures accurate precise dosing
‣ Fully integrated and interactive system, guides the operator right from entering the mix design, precise dosing, controlling the mixing time and ensuring homegenity of the final product.
‣ Multiple recipes can be saved
‣ Humidity percentage can be input and the system automatically adjusts the water inflow thus maintaining the water cement ratio.
‣ Batch report printed for every batch of concrete produced
‣ Final check of the quality of concrete produced
QUALITY CONCRETE
‣ Improved homogenization, reduced mixing times and greater quality of concrete
‣ Special double truncated cone-shaped drum with convex bottom
‣ Dual-screw mixing system
‣ Pressure sensor installed on the drum reduction gear box assists in confirming the homogenity of the concrete in the drum before discharging
ERGONOMICS AND SAFETY
‣ Closed cabin installed
‣ Ergonomic controls – multifunction joystick to the right of the operator
‣ Level 1 ROPS FOPS cabin - (Level 2 available as option)
COMFORT AND VISIBILITY
‣ Patented drum rotation feature combining the reversible driving allows full control over the mix directly from the cabin
‣ The 245° drum rotation, in fact, ensures complete visibility thus allowing the operator to check the consistency of the mix from the cabin
‣ Equipped with a standard ground control panel (always available to the operator) to manage, program and control water input into the drum, as well as the mixing/unloading functions and the activation of the hydraulic device for chute lifting/lowering
LOADING SYSTEM AND TIP-OFF
‣ Loading arm driven by Z-shaped auto-compensated kinematic mechanism with two lifting cylinders and two double acting loader cylinders
‣ Tip-off function to shed excess material before weighing and pouring in the drum
‣ Automatic unloading hatch - prevents any losses by avoiding spilling of materials
