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.
Bell Equipment is working on its biggest ever truck, which will offer a capacity of 55tonnes. A launch date has not yet been revealed for the hauler and technical details have yet to be revealed, however the machine will have a 4x4 drive system. Marc Schürmann managing director of Bell Equipment Europe said prototype testing for the machine will commence later this year. He said “Our competitors will be the smaller class of rigid haulers,” and he added that the aim is to offer lower fuel consumption and cap
John Deere Power Systems used bauma to complete its engine line-up for Tier 4 Final/Stage IV emissions regulations. This included the arrival of the PowerTechTM PWL 4.5L engine, which meets emissions regulations without a diesel particulate filter (DPF). Spanning outputs from 63-104kW, this four-cylinder, 4.5litre engine offers reduced cost and improves engine packaging by eliminating the DPF, said Deere. However, the engine uses selective catalytic reduction (SCR), a diesel oxidation catalyst (DOC) and coo

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.
