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.
A time-lapse video has been released showing the rapid replacement of the Barton Corner Bridge in Rhode Island in the US. Rhode Island Department of Transportation (RIDOT) partnered with EarthCam to document the US$6.4 million rapid replacement of the Barton Corner Bridge. The construction project was completed during an 11-day period in August 2014 and can be seen in an exclusive time-lapse, released by RIDOT. Had RIDOT had used conventional methods, the bridge replacement would have taken two full constru
High performance and productivity are claimed for the new generation DL200-3 and DL250-3 wheel loaders from Doosan Infracore. Powerful engines and a number of new features help reduce fuel consumption while these machines are also said to be easier to service and offer extended durability. The new cab design provides better visibility and more leg room, while it has a new instrument panel with an integrated VCU (vehicle control unit).

Haulotte has added the HT21RT and HT23RTJ to its self-propelled boom line-up. The HT21RT has a working height of 20.6m, up to 15.9m of outreach. It is available in both two-and four-wheel drive versions.
