Dynapac Expands Oscillation Technology within Roller Family

Dynapac’s foray into oscillation on a tandem drum roller came about four years ago with the 11-ton CO4200 VI. Since then, Dynapac has introduced the oscillation technology on its CO5200VI (77-inch, 13-ton), CO2200 (59-inch, 8.5-ton), and the largest roller in the family, the CO6200VI (84-inch, 13.5-ton). The CO6200VI features vibration on the front drum and oscillation on the rear. The large roller also addresses two pain points contractors have shared:

One: Dynapac addressed the premature wear some contractors have experienced on the drum shell from the rubbing action against asphalt material by constructing the drums out of Hardox® 450 steel, which is the hardest steel that can be shaped into a drum shell.

Two: Dynapac addressed the inconvenience of changing the timing belts of an oscillating drum’s off-center eccentric weights. While the job often requires dismantling a drum in a shop, Dynapac has designed the drum so the timing belts can be replaced in two hours, and can be done in the field if necessary. They’ve prepared a one-minute video showing the process at https://youtu.be/yMvPNuJY_EM.

Dynapac will focus on technology and new products in its booth 30931 in the central hall at CONEXPO-CON/AGG.
