CarriageMachine fitted with two steel tracks and rubber shoe pads. Track tension is assured by a grease piston with a shock absorbing system.
TransmissionTwo hydrostatic transmissions are each fitted with a variable displacement pump feeding fixed displacement axial piston motors directly splined to a two speed gearbox. Planetary final reduction gears in oil bath. An electro-hydraulic servo-control consents machine starting and stopping (for asphalt supply, etc.) with no pre-set working speed variation. Machine steering is operated by a steering wheel that controls the variable displacement pumps electric servo-controls. This system guarantees a precise speed and direction.
Screed RB 4650Consists 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. Whenever the paver stops during work operations (for asphalt supply, etc.) the pistons lifting the screed automatically block. These pistons prevent the screed from leaving marks on the mat. The smoothing plates, made from wear resisting indeformable steel, are heated by eight LPG burners. The screed is fitted with electronic ignition and automatic adjustment of the smoothing plate temperature.
Screed AssistThe 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 tracks of the machine, thus increasing machine traction.
BrakesThe hydrostatic drive acts as the service brake; the safety and parking brakes are mechanical multi-disk brakes with negative hydraulic control.
Driving Position and ControlsFitted with two sliding platforms. Each platform is equipped with an adjustable sliding seat. The console panel, fully equipped with main operating controls and warning lights, can be positioned in both driving positions consenting an excellent view from both sides.
Hopper and Feeding SystemThe 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, made of wear-resisting steel, are independently controlled. Two automatic stop feed devices control conveyors operation. Material conveyed to both sides is spread by two independently controlled augers. Rotation speed can be varied automatically to ensure a homogeneous distribution of material before the screed. Two ultrasonic wave detectors control proportional auger movement. Augers height can be adjusted hydraulically. A pair of auger extensions are supplied with the machine.
Electric System24 V system with 2 batteries 100 A.h.. Complete lighting system for work and travel.
