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.
Hydra shearer drums, now part of the ESCO family of mining products, have been engineered with radial-style picks and tool holders that are recessed into the vane to deliver optimum cutting performance. The result is reduced wear on the drum, increased product size and lower power consumption. The range of shearer drums can also be equipped with conical style picks.

This year’s 50th anniversary of the first edition of Samoter in Verona, Italy, could mark the start of a construction equipment sales’ renaissance for a nation with a rich construction equipment manufacturing heritage. Guy Woodford reports
It’s been a tough few years for the Italian construction equipment manufacturing industry. A difficult domestic and wider European sales market coupled with a challenging European economic climate has created something of a perfect storm. But many Italian and other Eur
