WIRTGEN’s cold milling machine product portfolio ranges from 35 cm (the W 35 Ri model) up to 4.40 m (the W 250 Fi) of milling width and up to 35 cm of milling depth. Small, compact and large cold milling machines by WIRTGEN are designed to execute various tasks such as concrete and asphalt removal or levelling road surfaces. Smaller models are suitable for work in city centres and restricted areas, while the larger machines are useful at airport runways or highways. The German manufacturer currently offers around 15 models in the cold milling machinery segment.

Recyclers/Soil stabilisers

On-site preparation of the asphalt surface is a job for the cold recycler. They are ideal for repaving the soil by granulating the existing pavement and adding a binding compound. Soil stabilisers are capable of transforming less stable soil into a high-quality material. This is achieved by mixing binders into the existing unstable soil. WIRTGEN’s product portfolio includes the WS 250 tractor-towed stabiliser, the WR series of compact recyclers with maximum working width of 2,400 mm and 560 mm of working depth, the CR series of cold recyclers and the robust KMA 240i mobile cold recycling mixing plant.

Binding agent spreaders

WIRTGEN offers a wide range of Streumaster binding agent spreaders. The individual models are designed as mounted, towed or truck mounted. Compact tractor-mounted units such as the SW 3 FC are suitable for restricted spaces and small sites. Towed trailer spreaders of the TA and TC series offer increased performance compared to mounted units with larger hopper volumes. Nevertheless, the best-performing models are the MC series truck mounted binding agent spreaders that are designed to match various carrier vehicles. The largest model, SW 422 MC has a container capacity of 22 m³ and offers a working width of 2,360 mm.

Slipform pavers

The German manufacturer currently lists offset slipform pavers, inset slipform pavers as well as texture curing machines. The SP series of offset slipform pavers offers ability to produce monolithic concrete profiles usable as walls, gutters or paths. On the other hand, inset slipform pavers place concrete directly in front of the machine and distribute it evenly. As the machine advances, the concrete is compacted by vibrators in the required thickness and width. WIRTGEN also offers TCM series of texture curing machines that give the concrete pavement the requested surface texture.

Surface Miners and Cross Application Miners

Surface miners are robust machines designed to work in harsh conditions of open-pit mines. They are capable of extracting valuable materials such as coal, rock salt, gypsum or limestone. The SMi series of WIRTGEN surface miners ranges from smaller models such as the 220 SMi to the giant 4200 SMi model with cutting width of 4,200 m, cutting depth of 830 mm and operating weight of 204 tonnes. Cross application miners are more versatile and suitable for e.g. lowering tunnel floors, construction of harbours or cutting roads and rails. WIRTGEN 260 SXi surface miner weighs over 100 tonnes and offers cutting width of 2,750 mm.
