Ammann says its latest pneumatic tyred model meets the tough emissions requirements for Europe and the US
Major manufacturers are revealing improved ranges of asphalt compactors to meet high performance requirements – Mike Woof writes
The latest generation of asphalt compactors are offering increased performance and capacity over earlier generation models, while using less fuel and having longer maintenance intervals.
Developed by6791 Ammann, the new ARX 90 and ARX 110 tandem rollers are available in both Tier 4Final/Stage IV variants for use in Europe and North America, as well as Tier 3 versions for use in lesser regulated markets. These high performance units are the first Ammann vibratory rollers to feature oscillation. This system cuts out around 90% of the vibrations to surroundings from conventional vibratory systems. The new rollers combine the oscillating, back-and-forth-movement of the drum with a constant static load. The firm claims that this allows the units to reach specified compaction values more quickly.
For increased output, the ARX offers a combination of oscillation and the firms heavy-duty, two-stage vibratory drum. This said to offer easy adjustment of amplitude and frequency. The optional ACE system offers measurement in absolute values and evaluation of material stiffness. It also provides an operator guidance function and can document the whole compaction process.
The company has also upgraded its rubber tyred asphalt compactor offering. The revamped ART 240 meets Tier 4 Final/Stage IV emissions requirements and has a large cab with good all round visibility. Novel features to maximise performance in different conditions include a front isostatic oscillating axle and a rear-drive system that provides the required power, regardless of tyre pressures or ballast weight.
The new206 Dynapac CG2300 has steering on the drums and comes in addition to the firm’s articulated CC machines. The CG2300 is 3.99m long, 2.99m high and has an inner turning radius of only 2.65m, and an off-set as big as 1.2m. It can be operated in confined spaces and the offset allows it to operate close to kerbs or highway barriers.
The CG2300 has an ECO Mode that reduces fuel consumption by over 15% and lowers operating noise. Working noise is also reduced by a hydraulic, temperature-guided cooling fan. A double pump vibration system makes the system more efficient, aiding servicing and further lowering fuel consumption.
German rival228 HAMM is also offering new tandem rollers in the shape of its DV+ models. Marketing manager Gottfriend Beer said that while the DV+ concept were developed for Europe, “…now the US is interested in this machine.”
Beer said that the demand for compaction quality is seen worldwide and that the 7tonne and 9tonne DV+ models can be offered with vibration and oscillation options. Variants include the double vibration (VV), vibration and oscillation (VO) and combi (VT) models. The 9tonne class DV+ 90i models have 75kW diesels while the 7tonne class DV+ 70i models have 54.6kW diesels as well as automatic transmissions for smooth acceleration and precise control. Turning circles are said to be tight and the machines have split drums as standard to help with quality.
Also new from HAMM is the GROW 180i, a pneumatic tyred roller aimed at finishing duties. This model can be ballasted up to 18tonnes and shares similar exterior dimensions to the existing top-of-the-range GRW280 model, which can weigh up to 28tonnes. The GRW 180i is offered in two versions, the GRW 180i-10 with a 10tonne basic weight and the GRW 180i-12H with a 12tonne basic weight. Power comes from a Tier 4 Interim/Stage IIIB compliant Deutz diesel rated at 55.4kW.
The machine features the firm’s extended variable ballast concept, which is also offered on the larger GRW 280i.
