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.
Dana used bauma 2013 to show a hydraulic hybrid concept for use with wheeled loaders, offering the potential to reduce fuel consumption by 20-40%. Called PowerBoost, the system uses high-pressure hydraulic accumulators to store up fluid power that can be released to assist the engine in driving hydraulic pumps and motors. “PowerBoost offers hydraulic power assistance to almost any machine function, to prevent peak loads on the engine during short duty cycles such as loading,” said Donald Remboski, Dana vice
Sandvik DC125R is a new member to the proven Sandvik DC family of compact, rubber-tyred top hammer drill rigs. The fully remote-controlled, hydraulic and self-propelled mini-sized drilling unit on a four-wheel drive carrier, is for drilling 22–45mm holes, and replaces the former Sandvik DC122R, one in the series of rigs originally launched in 1988 under the product name of Tamrock Commando. “A range of job site tests show that the new model offers better manoeuvrability than ever before. This is thanks to t
The Allu 3D Positioning System will make ground stabilisation works more efficient and more cost-effective, according to the Finnish manufacturer. The GPS-guided system works in conjunction with Allu’s PMX mixing head, which is mounted on an excavator. It is made up from four modules – computer unit with software, touch screen, base station and GPS antennas positioned on the mixing unit. Often used in road construction to firm up soft ground, the ground stabilisation process sees the binder material fed in
