The twin drum CC900 e and CC1000 e models are said to deliver the same power and performance of their diesel counterparts. Both rollers benefit from the advantages of electric drives, with savings on running costs, fewer moving parts, and low maintenance needs. They also have powerful batteries capable of completing a full day of operation without recharging. The CC900 e and CC1000 e deliver the same static linear load, amplitude, gradeability, and travel speed as the diesel-powered models on which they are based, with no compromise on productivity or job site performance.

In a typical working day, a 1.6tonne roller will be used for repairs and compaction of around 70 – 80tonnes of asphalt/day at a layer thickness of 40–50mm. In terms of area, this is roughly about 700 m2. Based on experience, this guarantees that the battery will last for a full day of work. In 90% of the cases in trials, about 20-30% of the battery level was left after the workday was over.

With the fast charger, 400V/three-phase system it takes 1.3 hours to reach 80% charging level. The 230V/single-phase charger needs 6 hours to reach 80% of capacity. Dynapac is planning to provide adapters allowing the use of automotive charging stations.

Both rollers in this segment are primarily used in road repair work and are intermittently used. With conventional diesel motors, this means that they are often left idling while the asphalt is raked into position. After compaction, the machines travel to the next repair site where they are also left idling for extended periods. With a standard diesel-powered machine, a great deal of energy and money is wasted. An electric roller does not idle when not in use. In addition, both models are quieter than conventional units, which is of extra benefit for use in urban areas.

One of the key features of the Marini Evo Dryer is the increased length of its dryer drum, allowing the plant to change the position of the RAP Introduction after the dryer flame and in turn providing plant operators with added versatility. As a result the aggregate heat exchange area stays constant, ensuring an efficient drying process.

In addition, to ensure the correct position of the flame inside the dryer drum a special long burner with internal protection is now available. This design means that the RAP introduction area is positioned after the flame, allowing a mixing area at the end of the cylinder, between the aggregates and the RAP. The design includes purpose-built mixing blades that reduce the stickiness of the RAP into the dryer drum.

The RAP can then be heated gradually, without being over-stressed by the high temperatures in the flame area. This allows the residual bitumen to be recuperated efficiently, without the risk of burning or drawbacks found with some conventional dryers such as high emissions and odour.

The Marini EvoDryer comes complete with another novel development, the new EvoDryer cylinder, which can be used to treat the fumes produced by the mixing tower in the discharge area of the mixer. A dedicated fan system sucks the diffused emissions produced by the mixer discharge. It also allows the management of the complete system and to convey emissions to the dryer discharge area behind the burner. A deflector inside the cylinder optimises the airflow emissions inside the drum, which are then flame-treated to burn off organic particles, reducing emissions and odours.

The standard version is 2.3m wide and 6.3m long, suitable for scaffolding pitches up to a maximum of 2.2m wide and up to 6.25m long. However, a Dynamo trailer is built according to the dimensions requested and can be customised according to the needs of the construction site and customer.

The trailer is also equipped with parking brakes on all wheels and can be towed by any vehicle on the site, even a forklift or van.

A variable counterweight is placed as needed under the chassis to set the weight of the scaffolding overhang.

Work areas can also be created below the road surface with any type of multidirectional scaffolding and pitch and, above all, with whatever geometry is needed to reach the extreme points on bridges, viaducts, and tunnels and generally any work to be served.

There is also a Dynamo Plus hydraulic model, only on request, that uses hydraulics for stabilsation expansion transverse displacement and alignment among other things.

The firm recognises also that using up to 100% RAP in the feed is dependent on the availability of quality material as well as effective logistics with regard to its retrieval and storage. For applications where lower quantities of RAP are to be used in the feed, Ammann also offers the RAH50 and RAH60 dryers, which have maximum usage of 50% and 60% RAP, respectively. In addition, the firm offers the RAC system, which can handle up to 40% RAP in the feed.

All Ammann recycling systems are able to produce high-quality mix with 100% virgin aggregate if so desired.
