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.
Caterpillar aims to boost its market share with the launch of its new high performance tandem asphalt rollers. Key upgrades include redesigned cabs new controls and improved diagnostics capabilities and better visibility will improve safety and ease of operation.
A special version of Hidromek’s HMK220LC excavator is now available for use in underground applications. This machine features additional reinforcement and protection to ensure its longevity in the tough underground application, as well as providing extra safety measures for the operator. The same Tier 4 Interim/Stage IIIB emission certified engine and hydraulics components are used as in the standard machines, although additional after-treatment systems are available to meet underground working requirement

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
