World premiere for Wirtgen
By Andy Brown02 March 2020
With the successful launch of its new generation of large milling machines, Wirtgen has made lasting improvements to the process of milling in terms of performance and efficiency.
The company has now added the W 220 Fi and W 250 Fi flagship models to its intelligent F Series; they will celebrate their world premiere at Conexpo.
The new W 220 Fi and W 250 Fi large milling machines serve a wide range of applications at a maximum milling depth of 350° mm – from surface course rehabilitation and fine milling work to complete removal of the surface.
Various drive concepts are available to ensure maximum, optimal milling performance. For example, the W 220 Fi is equipped with a two-speed Dual Shift powershift transmission, while the W 250 Fi has an Active Dual Power dual engine drive.
The company will also be displaying machines for cold in-place recycling. The tracked recyclers also deliver impressive results during full-depth recycling and high-performance milling.
The W 380 CRi will make its North American debut at the show set up as a recycling train with the Vögele paver SUPER 2000 - 3i including extending screed AB 600 TV+ and tandem roller HD+ 140i VVHF HCQ from Hamm.
The asphalt surface is removed, depending on the level of damage, by a recycling train operating across the entire width of the pavement in a single pass, mixed with binding agents on site, and then paved again immediately. The W 380 CRi can recycle the road surface to a full depth of 300 mm, so it is also suitable for full-depth recycling (FDR).
