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.
Doosan Portable Power is offering its new large 25/280 portable compressor, which meets Stage IIIB/Tier 4 Interim emission regulations. The 25/280 portable compressor has a free air delivery of 28.3m³/min at a rated operating pressure of 25.1bar. Dual pressure regulation is a standard feature of the 25/280 compressor, allowing it to supply compressed air at operating pressures of both 25.1 or 17.2 bar. Dual pressure regulation expands the scope of applications for the 25/280 compressor which includes poweri
Liebherr used INTERMAT 2012 to show its new 380 EC-B 16 Litronic flat-top crane. The 380tonne unit tops the 15-model range, which starts from 50tonnes. The new “flagship” can lift loads of up to 3,400kg at its 75m maximum radius. With the Litronic system, the 380 EC-B 16 can provide up to 20% more load lift at the push of a button. This is achieved by integrating the load-moment limiting system, the ABB operating-range limiting system and the MDA machine data evaluation program.
