Drive and return rollers

The optimum milling performance in WIRTGEN cold milling machines requires reliable milled material transport. A perfect interaction between all premium components is crucial to ensure high reliability and maximum performance. Besides the conveyor belt, the guide, support, drive and return rollers play a major role in ensuring this and have been specially developed for this task. Genuine WIRTGEN components excel due to their low-friction flow and high-grade roller bearings.

1 Thick-walled special rubber compound in the drive rollers with safe power transmission ensures a long service life. The diamond design prevents adhesion of asphalt.

2 The permanent bond between the rubber and metal ensures a long service life.

3 A curved outer contour results in an accurate belt centring.

4 The steel structure with support bars made of highgrade steel alloys and minimum manufacturing tolerances delivers reliable smooth running and a long service life.

5 Solid and open design principle supports the long-term dimensional stability even under extreme conditions and prevents adhesion of asphalt.
