Versatile and economical: Bomag tandem rollers with two amplitudes

Bomag is equipping its light tandem rollers in the 3 to 5 tonne class with a smaller amplitude of 0.2 mm in the front and rear drum. This new feature allows the best all-round tandem rollers models BW 135 AD-5 and BW 138 AD/AC-5 to be used on an even wider range of applications. From January 2018, the machines with optional double amplitude will be available worldwide.

A rotary switch allows the operator to simply switch between the low and large amplitude. On a variety of typical earthworks and asphalt applications, the high amplitude of 0.5 mm provides fast and economical compaction. The lower amplitude provides more sensitive compaction of thinner layers and minimises the risk of crushing aggregates. This results in uniform compaction and an excellent surface finish, leaving the earthworks and subgrade unaffected. In turn, this increases the efficiency and cost-effectiveness of compaction work. Tandem models with this new feature are particularly suitable for work on seams or joints in maintenance and repair work in towns and cities.

As in the past, the advanced tandem models BW 135 AD-5 and BW 138 AD-5 and the combination roller BW 138 AC-5 also provide low operating costs and high compaction power. The powerful 4-cylinder Kubota engine drives these tandem rollers which have a working width of 1,300 mm or 1,380 mm. The integrated measuring technology - the well-known Bomag Economizer - ensures perfect compaction control. The popular ergonomic driver’s stand with a clear all-round view and the intuitive controls allow the operator to work quickly and safely.

From January 2018, these versatile models with double amplitude will be available worldwide.
