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.
Models brought to bauma by Soilmec included two new multipurpose hydraulic crawler cranes for heavy-duty applications. Among key features of the SC-70 and SC-90 is a design that enables easy transport and set-up on site. The cranes are modular for fast conversion between a range of applications, such as use with a hydraulic or mechanical grab, hydromill, chisel, vibratory driver or clamshell. New Tier 4 engines are available.
The design and production of high powered tracked trenchers for linear excavation and bulk excavation and surface mining is one of many areas of expertise associated with the TESMEC Group. TESMEC also designs and manufactures machines and integrated systems for the stringing and maintenance of power lines; integrated solutions for the efficiency, the management and the monitoring of power grids; machines for the stringing, maintenance and diagnostic of railway power lines; and the design and production of G
Komatsu used INTERMAT to take the wraps off two new Dash 7 wheeled loaders, badged WA380-7 and WA500-7. With engine emissions being the main driver, the smaller 18-tonne WA380-7 packs 142kW from its EU Stage IIIb engine to deliver improved efficiency and lower fuel consumption. The machine also gets torque converter lock-up with the function operating in 2nd, 3rd and 4th gears, and gives the loader a 40 km/h forward speed.
Sandvik Mining is now using Volvo Penta engines in its underground trucks and loaders. The advanced engines meet Tier 4 Interim/Stage IIIB emission standards and are claimed to reduce fuel and ventilation costs in comparison with other units. The Volvo Penta engineers designed a selective catalytic reduction (SCR) unit in the exhaust system that converts NOx gas into nitrogen and water. The Volvo Penta exhaust-treatment solution also reduces DPM levels without the need for a diesel particulate filter (DPF).
