The CA6000: fifth generation roller
206 Dynapac’s new fifth generation CA single drum vibratory rollers are the first of their type with cross-mounted engines and they can run using a mix of biodiesel and diesel.
The CA5000, CA6000 and CA6500 compactors feature a fuel-saving system designed to reduce fuel consumption and CO2 emissions and new design to make servicing and maintenance easier.
Among other new features are optimised amplitude for improved compaction performance and ‘Active Bouncing Control’ to prevent damage to the machine and over-compaction.
The three new CA rollers have static linear loads of 50, 60 and 65kg/cm, respectively. The amplitude of 2.1mm is designed to allow rock fill to be compacted in almost 2m-thick layers and the rock size can be up to 1m in diameter. This results in higher volume capacity and fewer passes to reach compaction specifications, said Dynapac, giving fuel savings and reducing the cost per compacted cubic metre.
The new CA rollers are available with Stage IIIB engines (prepared for Stage IV) from 201 Deutz. They can be used with a mix of biodiesel and fossil diesel fuel; some can be run on 20% biodiesel. A fuel-saving system is designed to minimise fuel consumption and CO2 emissions by ensuring that the roller does not consume more power than needed at any time.
Cummins used bauma to reveal the QSF3.8 – a four-cylinder engine platform delivering a power range of 63-89kW – which is ready to meet Stage IV/Tier 4 Final emissions regulations. Using only SCR for its exhaust after-treatment process, the QSF3.8 avoids the need for either DOC or DPF as a result of using a high-efficiency catalyst to convert oxides of nitrogen at lower exhaust temperatures while requiring only low doses of DEF, said the company.
Volvo Penta is introducing start/stop technology that could cut fuel bills by 5% by turning off engines when they are left idling. Such systems have become increasingly common of late in private cars, where they stop the engine while waiting in a queue or at a red traffic light.

Among Rapid International’s will be the Rapid RP375 planetary mixer, which is said to be popular with both the precast and ready-mix industries. The Rapid RP375 mixer's planetary mixing action produces a homogenous mix ensuring high quality concrete every time, says the company, which will also offer information on the new Rapid Transbatch, the latest model from its mobile batching plant range.
