Bomag has introduced Tangential Oscillation (TanGO) on its BW161ADO-4 tandem roller.
TanGO is based on closely coordinating the exciter system to drum weight ratios. With TanGO always directed horizontally, it maintains continuous ground contact. The interaction of TanGO oscillation from the rear drum and traditional vibration power from the front drum provides practical advantages on difficult-to-compact asphalt mixes, Bomag says.
Target applications for the technology include work on bridge structures and in close proximity to buildings. Intermediate and finish rolling are additional applications.
Bomag plans to incorporate the technology into other roller weight classes in the future.
