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.
New to the Tesab range of crushing and screening equipment is the 1200TC tracked cone crusher, a development that completes the company’s range of crushing and screening equipment. The 1,200mm diameter cone crusher unit is a well proven design having established itself in static applications in Scandinavia and Australasia.
Engine supplier Yanmar will show a full range of California Air Resources Board (CARB) certified engines at Bauma. The company claims to be the first engine manufacturer to achieve the CARB accreditation across its complete line-up in the 19-56kW (25-75hp) range, and the engines all meet the US Tier 4 Final standard too. The firm will also announce an electronic diagnostic service system called Smart Assist-Direct. The system allows rapid updates of engine software and can automatically retrieve technical s

Synthetic diamond division of DeBeers, Element Six, has developed the 3D Percussive Diamond Insert (PDI) that it claims will radically cut costs in the mining drill industry. The 3D PDI uses the firm’s polycrystalline diamond technology to optimise wear and impact resistance properties, while improving penetration rates for the drill bit. The firm claims that tests of the drill insert show up to 10 times the drill life of a conventional tungsten carbide insert., greatly reducing costly rig downtime for serv
