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.
Lintec’s Aggregate Cooling System (ACS) is described as a new, patented and fully containerised plant concept for the direct cooling of aggregates for concrete mixes. Being showcased at bauma, ACS is said by Lintec to work in a desert environment without the usual and costly addition of specifically produced ice.
Element Six, the synthetic diamond division of DeBeers, has developed a revised design for its D Power road picks, claiming greatly extended working life. The D Power road pick will use a polycrystalline diamond (PCD) tip with an improved head design that incorporates tungsten carbide to provide greater protection to the steel pick mount. The company claims that the D Power road pick can deliver up to 40 times the life of a standard carbide pick, providing reduced downtime, increased efficiency and a better
