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.
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.
The novel cranes sheaves now being offered by component specialist Nylacast are said to extend rope wear life and reduce maintenance needs. The innovative polymer formulation shares technology with the proven Bigfoot outrigger pads, which help with load distribution in crane lift applications. The new polymer sheaves are said to offer key benefits over existing steel sheaves such as lower weight, which makes them easier to handle during installation or replacement.
