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.
While draglines are now a rarity, Sennebogen showed its 50tonne operating weight duty cycle crawler crane, the 650HD, with 2.33 dragline bucket. The machine is one of a 10-model range with operating weights from 20-180tonnes and engines between 119 and 708kW. It can be used in civil engineering, mining, demolition or material handling.
The new generation JS crawler excavators from JCB are said to deliver increased performance along with reduced running costs. The JS220, JS260 and JS360 are all powered by Isuzu diesels that meet the Tier 4 Interim/Stage IIIB emissions requirements with reduced fuel consumption and increased torque rise. For developing markets, there is also a Tier 2 compliant version of the JS220 powered by a JCB 448 Dieselmax engine with a similar output to the 129kW Isuzu diesel in the Tier 4 Interim/Stage IIIB model.

Doosan’s DX300LC-3 and DX340LC-3 excavators get the Korean maker’s DL08K common rail six-cylinder turbocharged diesel engine meeting stage IIIB emission regulations thanks to EGR and DPF technologies.
