Sakai is offering an innovative alternative for oscillation compaction in the shape of its latest SW888ND-1 model. This machine differs radically from other compactors on the market featuring oscillation as an option. Its rivals all feature oscillation on one drum, with conventional vibration on the other.

However Sakai’s novel design offers both oscillation and vibration on both drums. This allows the user a wide degree of compaction modes, with the options of either oscillation or vibration on both drums or just one drum. And Sakai claims that its novel feature of both oscillation and vibration for both drums means that offers increased productivity over rival units. The machine can achieve compaction density in half the number of passes as both drums can deliver the correct form of compaction, whichever the requirement for the specification.

Sakai's novel oscillation compactor is said to offer twice the productivity of rival machines according to the firm
As with other rollers featuring oscillation, the machine suits duties such as compacting on bridges or in urban areas. In the former instance conventional vibration could cause structural issues and in the latter, vibration could cause disturbance, upset sensitive computing equipment or potentially damage nearby historic buildings.

The oscillation and vibration mechanisms are gear driven rather than featuring belt drives, which reduces maintenance needs significantly according to the firm. The machine weighs 13.5tonnes if fitted with a canopy and 14.3tonnes if specified with a cab, while power comes from a Deutz diesel rated at 90kW. It features 1.37m diameter drums that are 2m wide and operates at a frequency of 46.7hZ, with a maximum amplitude of 0.55mm.

The firm is also offering its TW354W-K and SW354W-K models, which are more basic machines aimed at the rental market. The machines share the same basic structure, with the former being the combination version and the latter being the double drum variant. The machine has a 1.3m drum width, which measure(s) 675mm in diameter, while power comes from a 26kW Kubota diesel.
