Benefits & Features
Carriage
Triple axle carriage; two steering axles and one drive axle. Four large steering bogey wheels mounted to the front oscillating axle rocker arms. The rear tires assure a good adherence even on irregular terrain. Two oscillating and adjustable push rollers are fixed to the front part of the machine.
Transmission
Hydromechanic transmission. A variabledisplacement pump feeds the drive system fitted with a twodisplacement piston motor directly connected to the gearbox. An electric servo-control consents machine starting and stopping (for asphalt supply, etc.) with no preset working speed variation. Self-locking differential with final reduction gears in oil bath.
Screed
The screed consists of two central fixed plates and two lateral mobile plates, hydraulically operated, sliding on a telescopic cylindrical guide chromium plated. The smoothing plates are made of wear resisting undeformable steel. The easy modification of the plate axis allows modifications of shapes (V W ) with different angles (+4.5%; -2.5%) according to the job requirements. When the machine stops (for asphalt supply, etc.), the two screed jacks automatically lock in order to avoid undesired marks on the material laid.
