March 2011 â€“ Wirtgen America, Inc. introduced its largest and most sophisticated cold mill, the W 250 â€“ along with the new EVO Series of Kleemann track-mounted, mobile impact crushers, and HD+ tandem and GRW-class pneumatic rollers from Hamm â€“ at Conexpo-Con/Agg 2011 in Las Vegas in March.
Those new products are among the nearly 30 new or revised products that were on display.
The 980-hp. dual-engine W 250 joined two new cold mills introduced in 2010, but seen at Conexpo-Con/Agg for the first time: the new W 200 single engine model with milling drum assemblies of 59 in., 79 in., or 87 in. working width, and the similarly sized W 210 dual engine model, offering more power at lower fuel consumption.
On display was the new MR 110 EVO mobile impact crusher plant. Kleemannâ€™s EVO line constitutes the next generation of impact crushers, and represents a genuinely new evolution for the entire plant spectrum in terms of performance, economic efficiency and equipment longevity.
New at Conexpo-Con/Agg from Wirtgen America was the Hamm HD+ 110 VO, an all-new 66-in. tandem roller, with an operating weight of 11.5 tons, featuring both conventional vibration and exclusive Hamm Oscillation compaction. Also new were the HD+ 120 VV HF and HD+ 140 VV rollers â€“ introduced at World of Asphalt 2009 â€“ with their respective operating weights of 13.2 and 15.4 tons, and respective drum widths of 78 and 84 inches.
And seen for the first time in North America was the Hamm GRW 280, an advanced-design eight-wheel pneumatic roller. With an operating weight between 10 and 30 short tons, the GRW 280 provides exceptional operator visibility, a new, â€śintelligentâ€ť ballasting concept, and the highest safety standards.
With the exception of a handful of models, all equipment exhibited was either new to Conexpo-Con/Agg, or improved while retaining the original model numbers.
Highlights of the Wirtgen America display included the following machines new to Conexpo-Con/Agg 2011:
o Wirtgen W 250. The W 250 marks the advent of an absolutely high-performance cold milling machine with a maximum power rating of 980 hp. The new large milling machine can remove up to 1,300 tons of asphalt per hour.
Like the W 210, the W 250 incorporates Wirtgen’s innovative Dual Engine Concept, which in the case of the W 250 allows milling with one engine at 610 hp, or milling with two engines at a more powerful 980 hp. Six different milling widths ranging from 87 in. to 14.4 ft. The W 250 is also equipped with WIDRIVE, the intelligent Wirtgen machine management system, which not only eases the workload of the operator, but also guarantees fuel efficient and environmentally compatible milling.
The W 250 is able to mill large job sites on dual-lane highways or airport runways at top speed. The Wirtgen W 250 can remove asphalt layers with a milling depth of up to 13.8 in., and tough portland cement concrete pavements, at a high forward speed.
o Kleemann MR 110 Z EVO. The new MR 110 Z Â EVO is a universally adaptable plant which is suited for processing both blasted natural stone, asphalt and demolition waste, as well as producing a first-class end quality product. Despite its comparatively small crusher inlet dimensions of 3.6 x 2.6 ft. (1100 x 800 mm), it achieves outputs that up to now were only known to be achievable with larger crushing plants. Maximum input capacities of 350 tph easily can be achieved.
The new EVO concept matches refinements for all individual components with a new material flow concept. The new, highly efficient material flow concept of the EVO models eliminates all restriction to the flow of the material throughout the entire plant.
For example, the discharge chute under the crusher is 4 in. wider than the inner width of the crusher, and the subsequent discharge belt is another 4 in. wider than the discharge chute. Material is thus transported quickly and carefully away from the critical area under the crusher, with flow rate increased, and wear reduced.
o Kleemann MC 110 ZS. The MC 110 track-mounted jaw crusher â€“ with its high-torque reversible hydraulic jaw, and fully hydraulic gap adjustment â€“ makes this model a great contractor’s crusher. The R version has an integrated grizzly and the Z version a fully independent double-deck pre-screen. The machine also
can be fitted with an optional final screen and oversize discharge, allowing the operator to produce a final graded product with one machine.
o Hamm HD+ 110 VO. At Conexpo-Con/Agg 2010, Hamm Compaction Division introduced an all-new 66-in. tandem roller, in two different weight classes. The new HD+ 110 platform has an operating weight of 11.5 tons, and the new HD+ 90 platform features an operating weight of 10 tons. Both platforms will offer a variety of different options, including conventional vibration, high frequency compaction at 4,020 vpm, exclusive Hamm Oscillation compaction, a combination option, and even a split-drum option. The HD+ 110 VO incorporates vibration and Oscillation in a single platform.
It was joined by Hammâ€™s HD+ 120 VV HF and HD+ 140 VV rollers. These new
articulated tandem compactors â€“ with respective operating weights of 13.2 and 15.4 tons (12 and 14 metric tonnes) have set new standards with an unprecedented amount of cabin space, perfect visibility conditions for the driver, and very impressive performance data.
o GRW 280. New to North America at Conexpo-Con/Agg 2011 was the revolutionary-design GRW 280 pneumatic (rubber-tired) roller from Hamm, with an operating weight between 10 and 30 short tons. In the operator’s workplace, instead of the previous setup with two seats, the new GRW offers one comfortable, adjustable seat and thus maximum freedom of movement. For the first time ever, viewing channels in the frame structure offer a view of the edges and the tires of the outer wheels. What’s more, a novel suspension of the front wheels allows for an uninterrupted view towards the front.
o W 50 DC Rumbler. Introduced at Conexpo-Con/Agg 2011 was the W 50 DC Rumbler. The W 50 DC Rumbler is a standard W 50 DC cold milling machine with an optional Rumbler attachment installed, providing high-production, high-profitability cutting of milled rumble strips in the standard, preferred 16-in. width at speeds of up to 180 fpm.
