The BB650 is a triple-axle rubber-tyre paver. It is designed for high production and optimum maneuverability.Augers and conveyors of BB650 paver are independently controlled. Rotation speed varies automatically according to the quantity of material required for a correct feeding of the screed.BB650 typical applications are secondary roads, national roads, freeways, large parking lots and urbanizations.Screed available: RB4650. Standard Paving Width: 2.5 m - Maximum Paving Width: 6 m.

Carriage
Triple axle carriage; two steering axles and one rear traction axle. Four large steering bogey wheels mounted on two equalisers. Two oscillating and adjustable push rollers are fixed to the front part of the machine.Transmission
Hydrostatic transmission. A variable-displacement pump feeds the drive system fitted with a fixed-displacement axial piston motor which is directly connected to the gearbox. An electric servo-control consents machine starting and stopping (for asphalt supply, etc.) with no preset working speed variation.Selflocking differential gear with final reduction gears in oil bath.Screed RB 4650
Consists of two central fixed plates and two lateral mobile plates, hydraulically operated, sliding on two chromed telescopic cylindrical guides. The screed plate axis allows modifications of shapes (V W ) with different camber angles between +4.5% and -2.5%. Other adjustments allow tamper travel position to be corrected due to wear. When at work with the machine stopped (for asphalt supply, etc.), the pistons lifting the screed automatically block to avoid marking the mat. The smoothing plates are made of wear resisting indeformable steel and are heated by eight gas propane burners. The screed is fitted with electronic ignition and automatic adjustment of the smoothing plate temperature.Screed Assist
The screed is equipped with an electro-hydraulic device maintaining a constant screed pressure on the bituminous mix, independently from the mix bearing capacity and the paving width. It is also possible to transfer part of the screed weight to the drive axle of the machine, thus increasing remarkably its adherence to the ground.Brakes
The hydrostatic drive acts as the service brake; the safety brake, which consists of is a multi-disk brake with a negative hydraulic control and hydraulic calipers and a brake booster, is controlled by a pedal from the operator's seats; the parking brake is applied by 2 calipers with negative hydraulic control. The safety and parking brakes act on the shafts coupled to the drive wheels.Operator's Seat
The machine is fitted with two adjustable seats and a sliding console panel. Sliding operator seats are available on request and can be positioned outside the machine frame in order to guarantee maximum view from both sides of the machine.Hopper and Feeding System
The independent movement of the two side wings is obtained by means of two hydraulic cylinders. The bottom plate of the hopper is built of abrasion-proof steel. Two conveyors, independently controlled each side, are made of wear-resisting steel. Material conveyed to both sides is spread by two augers, each of them independently controlled. Rotation speed varies automatically according to the quantity of material required for a correct feeding of the screed. Four automatic stop feed devices control the conveyors and the augers. A pair of auger extensions are supplied with the machine.Electrical-Electronic System
An electronic circuit, which governs and operates the hydraulic system, gives the machine an exceptional self-government. 24 V electric system with two 100 A.h batteries. Complete lighting system for work and road circulation.Controls
The machine is hydraulically controlled and electrically operated by means of simple switches. In case of a breakdown all solenoid valves of the hydraulic system can be manually operated so as to avoid machine stops. All main machine components are easy to service. Machine meets Tier 2 (EPA U.S. standards), Step II (European standards) emissions requirements.On Request
