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.
Case’s 12.2tonne 621F wheeled loader will make its first appearance at a European show during bauma. Powered by a second generation common-rail Tier 4 interim engine and benefiting from the use of fuel saving SCR technology, the 621F is said to have proven ZF auto powershift transmission and heavy duty axles. The model is also equipped with a 100% locking front differential for maximum traction and reduced tyre wear. Similar to other larger Case F Series wheeled loaders, the 621F has a cooling pack directly

Sandvik Construction has added the DC125R to its DC family of compact top hammer drill rigs. The remote-controlled self-propelled rig has a four-wheeled carrier that can also be equipped with rubber tracks for added mobility in difficult terrain. Capable of drilling 22-45mm diameter holes, the machine is capable of up to 300-400m3 in an eight-hour shift. The 3,150kg mini rig is powered by a 37kW engine that drives a 5.5kW rock drill. Designed primarily for foundation drilling, road cutting, trenching, line
