BOMAG introduced Tangential Oscillation (TanGO) on its new BW161ADO-4 tandem roller model.

This well established exciter system has been assessed and further optimized in key areas. The result is improved power for vibration generation and perfectly matched compaction parameters, along with reduced drive belt maintenance requirements.

BOMAG oscillation makes use of the physical laws of vibration generation to its best effect. The careful coordination of exciter system to drum weight ratios is the basis for BOMAG’s tangential oscillation. Target applications for this compaction technology are on bridge structures and for working in close proximity to buildings. Intermediate and finish rolling are additional proven applications.

With TanGO always directed horizontally, it maintains continuous ground contact and efficient compaction. Results may be seen immediately after a few roller passes. 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. This provides desirable smoothness and density.

This system offers modular design and an extremely wear-resistant drum wrapper surface. The drum wrapper shell is covered by an 8-year/8,000-hour warranty.
