Dynapac CO6200VI tandem drum roller will now have vibration on the front drum and oscillation on the rear. The CO6200VI Dynapac roller is a 13.5-ton unit and has an 84-inch width.
According to Dynapac, oscillation creates a rubbing action on the asphalt material that can lead to premature wear on the drum shell. Drum on the CO6200VI are built with Hardox 450 steel, which it says is the hardest steel that can be shaped into a drum shell. It carries a pro-rated warranty of seven years / 7,500 hours.
Timing belts on Dynapac’s oscillating drums can be replaced in two hours and can be done in the field if necessary.
Watch a demonstration of the belt-changing process.
