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.
Liebherr is launching a revised R922 crawler excavator, replacing the previous R906 and joining the R918 and R926 in the company’s medium weight line-up. Powered by a Stage IIIB Liebherr diesel engine, developing 105kW (143hp), the R922 weighs in at 22 tonnes and designed as a general purpose civils machine. Using a Dual Circuit Positive Control hydraulic system, the excavator is said to consume less energy than previous models, resulting in fuel savings for the customer.

The new 673 telescopic crawler crane from Sennebogen is said to be powerful, efficient and stable in operation. The machine offers a lifting capacity of 70tonnes crane while its telescoping boom is said to maximise versatility for an array of lifting applications. The new 673 R-HD is said to be rugged and durable and is the first telescopic crawler crane in the firm’s new E-series. Key features include stability and ease of transport, as well as fast set-up times. For on-road transport the crane is less tha

While draglines are now a rarity, Sennebogen showed its 50tonne operating weight duty cycle crawler crane, the 650HD, with 2.33 dragline bucket. The machine is one of a 10-model range with operating weights from 20-180tonnes and engines between 119 and 708kW. It can be used in civil engineering, mining, demolition or material handling.
