Carriage
Tracked machine with two rubber shoe crawlers. Track tension is achieved by two grease pistons and a shock absorption system. These type of tracks ensures perfect stability, low noise level and excellent leveling performances as it reduces soilslope variations to a minimum.
Transmission
Hydrostatic transmission with two variable displacement pumps feeding two variable displacement axial piston motors directly splined to the planetary final reduction gears in oil bath. An electro-hydraulic servo-control consents machine starting and stopping (for asphalt supply, etc.) with no preset working speed variation. Machine steering is operated by a steering wheel that controls the variable displacement pumps electric servocontrols. This system guarantees a gradual and precise steering.
Screed RB 260
Fitted with two central fixed elements and two hydraulically operated side mobile elements. The two side elements slide on a chromium plated telescopic and fixed guide. Bushes are oversized to resist shocks and vibrations. Smoothing plates are made from wear resisting shaperetaining steel and are heated by four LPG burners, one fitted to each element. Screed vibration is hydraulically controlled and applied over the complete length of the screed. Variable paving width is obtained by electro-hydraulic distributors. The screed plate axis allows modifications of shapes (V W ) with different camber angles between +4.5% and -2.5%. Other adjustments allow recovery of the smoothing plate wear.onsists 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.
