Offset four-wheel design delivers single pass compaction

8591 CMI Roadbuilding has launched a three-model Rexpactor compaction line-up at CONEXPO-CON/AGG in response to previous customer requests. The updated RexPactor compaction machines have a four-wheel design, however the two front wheels are close together, inside the line of the rear wheels. This design ensures that all four wheels compact a different line, in effect delivering full-width compaction in a single pass. This layout also ensures that the machine can’t become bogged down with uncompacted material between the wheels.

There are three models available: the 17.2 tonne SP-3; the 22.7 tonne SP-5 and the 33 tonne SP-8. They deliver a distributed load of 81,156Nm, 91,212Nm and 99,877Nm respectively using an open-ring wheel design, rather than a solid padfoot roller wheel. Bottom-up compaction is achieved by forcing the wheel rings to sink into the soil under static weight.

The RexPactor range is designed for use in road construction, pipelines and other soil embankment construction. All three models can be supplied with a standard semi-U blade or with an optional tilt blade.

    May 30, 2013
    Paving machines vary considerably in North America compared with those units used elsewhere. On a worldwide basis, pavers with tamper bar screeds are popular having been developed in Europe and also favoured by Japanese and Chinese firms. But in the US the length of highways to be constructed resulted in a focus on high production pavers, which still continues today. North America and Latin America are key markets for these machines, with Australia being one of the few territories to employ both European an

    Also new from BOMAG are compact rubber tyred rollers for the 4.5-11tonne market. The new BW 11 RH-5 models are articulated and feature hydrostatic drives and suit use in compacting chippings on surface dressing. The central positioning of the articulated joint is said to allow the four rear wheels to roll in the gaps between the five front wheels even when driving round bends.
