Rear Loading Mixer DBS 4300

Unique in the field of self-loading concrete mixers, this very compact, agile and economical machine guarantees a yield of 4.3 m³ of concrete in every batch and a daily productivity of up to 105 to 115 m³. The DBS 4300 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 DBS 4300 with the computerized 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.

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 pump assists in confirming the homogenity of the concrete in the drum before discharging

ERGONOMICS AND SAFETY

Ergonomic controls – multifunction joystick to the left 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

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
Electro-Hydraulically operated hatch – prevents any losses by avoiding spilling of materials
