US focus for Wirtgen
By Chris Sleight17 February 2011
Wirtgen's stand will feature six milling machines, and the company says it will unveil a large new planer at ConExpo itself.
Other novelties will include the attachment mounted on a W 50 DC milling machine, This attachment allows high-production cutting of milled rumble strips in the standard, preferred 16 in (406 mm) width at speeds of up to 180 ft/minute (55 m/minute).
The company's stand will also include some of the machines launched at last year's Bauma exhibition, which are being launched in the US for the first time, such as the W 200 single engine and W 210 double engine milling machine.
The show will also be the first US appearance for the company's new SP 15 and sp 25 slipform pavers. The SP 15 features a 6 ft (1.83 m) maximum paving width and 4 ft 3 in (1.3 m) maximum curb/parapet height. Features include the ability to change quickly between left and right-sided pours and all-track steering for what Wirtgen claims is the tightest, smoothest turning radius in the industry.
The SP 25 meanwhile offers a 12 ft (3.66 m) paving width and the maximum mould height is 6 ½ ft (1.98 m). The machine is available with either three or four tracks, and both pavers feature an Eco mode, which matches engine revs to the load, minimising fuel consumption.
As well as its Vision series pavers, designed especially for the US market, sister company Vögele will exhibit the brand-new rear-mounted VR 600-2 extending screed. Like the Vision pavers, this screed has been developed specifically for the requirements of the North American market. It has a basic width of 10 ft (3.05 m) and extends fully automatically to 19 ft 7 in (5.97 m). A maximum width of 28 ft 2 in (8.59 m) is possible with bolt-on extensions. The screed is designed for use with the 10 ft (3.05 m) Vision 5200-2 (wheeled) and Vision 5203-2 (tracked) pavers.
Also on the Wirtgen Group stand will be the all new 66 in (1.68 m) tandem roller from Hamm, available in either the 11.5 ton or 10 ton weight classes.
The GRW 280 rubber-tyred roller meanwhile can have an operating weight from 10 to 30 tonnes (9.09 to 27.3 tonnes) and features a single adjustable seat that can slide the full width of the machine. A novel suspension design for the front wheels allows an uninterrupted view towards the front.
The Wirtgen Group stand will include the new MR 110 EVO mobile impact crusher from Kleemann. Suitable for asphalt, primary aggregates and demolition waste, it can achieve outputs of 350 tonnes per hour, despite the relatively small 1100 x 800 mm crusher inlet.
Design features include a discharge chute under the crusher that is 100 mm and the next discharge belt is 100 mm wider again. This prevents spillages and ensures a fast flow of material with reduced wear on the machine.
Also on show will be the MC 110 track-mounted jaw crusher.
