A unique product in the market of self-loading concrete mixers, this extremely compact, agile and price-worth machine provides a 4.0 m³ concrete yield and a daily productivity amounting to 90/100 m³ . The machines in the DB 460 range may be used as an alternative to small and medium-sized concrete-mixing systems, as they provide great handling (enhanced by the reversible driver’s seat and the drum rotation system for 360° download), flexibility and autonomy. Being equipped with an innovative computerised production system, the DB 460 machines are capable of producing top quality certified concrete. Consistency, repeatability and quality of the concrete batch are the unprecedented advantages offered by the CBV technology, an exclusive feature of FIORI GROUP’s self-loading mixers.


PERFORMANCE AND HANDLING
The front steering differential swing axle, together with the larger tyres and the high pressure automotive hydrostatic transmission, facilitates driving and machine control on any terrain. Compact and easy to handle, with 4-wheel-drive and steering, FIORI GROUP concrete mixers feature impressive off-road capabilities. Thanks to their handling and excellent off-road mobility, our vehicles can be placed at the jet position in all site conditions.


VISIBILITY and COMFORT
The patented system for the drum rotation also allows full control over the mix directly from the cabin, combining the reversible driving with the 360° dumping. The 245° drum rotation, in fact, ensures complete visibility thus allowing the operator to check the consistency of the mix from the cabin. In this position, the drum is rotated and the machine remains compact. DB 460 are 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
The loading arm is driven by a Z-shaped auto-compensated kinematic mechanism with two lifting cylinders and two double-acting loader return cylinders: thanks to a multifunction joystick it can be easily controlled by the operator. The special design of the loader-conveyor unit makes for an easier loading of materials in the drum. A dedicated closing hatch, driven by two cylinders and easily controlled by the operator through a multifunction Joystick, has the function of dosing the dumping (reducing cement powder spillage) and releasing excess material with decrement weighing before pouring in the drum (Tip-Off function).


CONCRETE BATCHING VEHICLE
The equipment on the CBV version includes an exclusive and accurate dosing system (integrated into an onboard computer through which multiple recipes can be saved by storing different components for each of them), as well as an instantaneous and final checking system of the quality of the concrete. This system guides the operator during mix design preparation, assuring a high dosing precision, homogeneity in the mix and therefore an extremely strong concrete. The humidity percentage can be input and the water to be pumped in the drum can be automatically compensated so that the water/cement ratio remains constant. A specific report is printed and certifies the features of the concrete produced.


QUALITY CONCRETE
The special double truncated cone-shaped drum with convex bottom and dual-screw mixing system allows for a better material homogenisation and quality while reducing the mixing time. Producing concrete at the moment of use allows for maximum performance of the cement hydration process, therefore avoiding the typical deterioration phenomena connected with climatic factors, excessive mixing, transport times, and inevitable building site operations interruptions. The pressure sensor installed on the drum reduction gear detects the data required to check the expected slump.
