The heaviest single drum roller in the world!

BOMAG has again extended the boundaries for soil compaction. At the 2010 bauma, BOMAG launched a new class of single drum roller (most notably in terms of its cost-cutting capability) with the BW 332 DEEP IMPACT, a 32 tonne roller, the heaviest single drum roller in the world!

The BOMAG BW 332 DEEP IMPACT masters near- impossible jobs and achieves previously unknown peaks of performance and efficiency. With a compaction depth of four metres, the BW 332 DEEP IMPACT displays previously unimaginable potential.

However, it is not operating weight alone that creates this unique level of performance. The BW 332 DEEP IMPACT brings together the following features for the first time:

-       32 tonnes operating weight

-       100 kg/cm static linear load

-       3.3 mm amplitude

-       750 kN centrifugal force

-       VARIOCONTROL vibration system

-       Polygonal drum

-       2.40 m working width

What do these statistics mean in practice? In total, 50% more compaction performance than the previously heaviest single drum roller, the 26 tonne BOMAG BW 226. The BW 332 DEEP IMPACT offers 35 % more compaction depth with its innovative technology. Even 4 metres down in trials, it produced compaction that had previously only been possible using other methods. Now the industry has a roller that combines maximum performance with minimum costs per m³. These benefits become apparent on earthwoks and in follow-up compaction work. Up to now, the existing subsoil often had to removed, stored temporarily and then re-laid and compacted in layers; or slow, expensive methods such as drop-weights, etc. had to be used. The BW 332 DEEP IMPACT makes the "compact-in-place" method possible. Specified soil bearing capacity can be achieved using this single drum roller alone.

A conventional smooth roller drum would be overwhelmed by the immense forces being generated. The drum would sink and vibration energy would be dissipated at the surface. The solution: the patented BOMAG polygonal drum. With its ingenious shape featuring plates and angles, compaction forces are directed vertically into the material with no loss of vibration energy. This creates optimum traction with low rolling resistance. The polygonal drum is also self-cleaning - power-draining scrapers are out.

Rolled output increases by 15 % with the polygonal drum's 2.40 metre extended working width. Together with the 35 % greater depth effect, the BW 332 DEEP IMPACT  has 50% higher overall performance compared to the BOMAG BW 226 single drum roller, which itself had been shown to be superior to other machines in the 26 tonne class.

The new single drum roller is much more than just a bigger version of an earlier model. For example, vibration forces equivalent to 75 tonnes presented a design challenge that needed the full expertise of the global leader. This giant roller operates without a single grease nipple making it easy to maintain. Its performance capability and reliability have been tested in very tough trials prior to production.

The BOMAG VARIOCONTROL vibration system automatically and progressively adjusts vibration to soil stiffness. This creates optimum, uniform compaction, without destroying soil structure. The environment is also protected against harmful vibrations. Vibration can be progressively adjusted to give minimal surface compaction up to maximum depth effect. Consequently the BW 332 DEEP IMPACT not only offers performance and flexibility, but compaction is documented with the integrated BTMprof. measuring system, which includes printer.

For deep-acting compaction on earthworks, follow-up compaction, dam construction - the BOMAG BW 332 DEEP IMPACT sets new standards for the lowest construction costs per m³ and the highest productivity.
