Wirtgen Group’s small milling machines deliver high-quality, cost-effective results for small-scale projects
On small project sites, whether the work is to be carried out on small areas or is a matter of repairing surface damage in certain places, the quality of the final results must still fulfil the highest standards. For jobs like these, the Wirtgen Group product portfolio offers a range of machines that harmonise perfectly in terms of application-specific suitability and cost-efficiency. In addition to the small milling machines from Wirtgen, these include the MINI class pavers from Vögele and the compact rollers from Hamm.
No more temporary patching
Among the classical applications are, primarily, small-scale repair and maintenance jobs in road construction. Removing road markings, working around road fixtures and the milling of gutters and slots are just as frequently represented here as repair work in flowing traffic, and the construction of cycleways and footpaths, farm tracks, car parks and sports facilities. The small machines fill in sewer trenches, pave floors inside industrial buildings or underground car parks and are also used on gardening and landscaping projects. The compact machines are particularly useful for repair and maintenance projects that have to be achieved within tight deadlines and deliver high-quality results with long-term structural integrity.
Small, versatile and multi-talented
The portfolio of small milling machines from Wirtgen ranges from the smallest milling machine, the W 35 Ri, and the half-metre class W 50 Ri to the 1-metre class models. Despite their compact dimensions, their daily productivity is enormous. Which they impressively confirm when rapidly removing surface layers or milling out several layers at a time. Small rear loaders such as the W 120 Ri can even remove complete asphalt packages up to a depth of 30 cm and a maximum width of 1.2 m.
The rapid completion of construction projects with small milling machines is enabled by single-handed operating and high travel speeds of up to 12 km/h. A further advantage here is the FCS quick-change system for milling drums. It allows the fast and simple exchange of milling drums with a variety of working widths and tool spacings. This means that both standard milling and fine milling applications are possible. The outstanding manoeuvrability of the machines enables the milling of tight radii when milling around manhole covers.
Small size guarantees efficiency in all situations
Whether on construction sites with narrow or tight situations or low headroom – wherever space is severely restricted or small paving widths are required, the smallest Vögele pavers, the MINI 500 and MINI 502, or the compact SUPER 700i and SUPER 800i pavers, are always the ideal choice. They offer paving widths as low as 0.25 m to 3.5 m and can eliminate the need for manual work. The MINI class pavers enable contractors to achieve even the smallest projects more conveniently and with higher efficiency and quality with a machine.
Vögele Compact Class pavers are therefore the ideal choice for small to medium scale construction projects. Depending on the model, the SUPER 1000i, SUPER 1003i, SUPER 1300-3i and SUPER 1303-3i machines offer paving widths from 0.75 m to a maximum of 5.00 m.
Small and versatile
With operating weights of between 1.5 and 4.5 t, the HD 8 – HD 14(i) articulation steered tandem rollers are true all-rounders not only in the use of construction of roads and paths, but also on gardening and landscaping projects. Not only crushed stone, frost protection and base layers, but also water-bound road surfaces and asphalt layers can be ideally compacted with the tandem rollers of the HD CompactLine series. Depending on the construction material and the required compaction depth, the best results are achieved with vibration, oscillation or combination rollers. With eight electrically powered rollers, Hamm also offers a range of solutions for zero operating emission compaction. The HD 10e / HD 12e models (drum width: 1 m / 1.20 m, operating weight: 2.5 t / 2.7 t) offer exactly the same compaction performance as their combustion-engined counterparts, but with zero operating emissions. The operating system of the e-rollers is almost identical to that of the other models in the HD CompactLine series.
A special highlight: more creative freedom with coloured asphalt
Promote sustainability by adding specialities: the use of coloured asphalt is an excellent way for urban planners, landscape designers and construction companies to create special paving effects. The mix is produced using ‘colourless bitumen’, a synthetic binding agent based on mineral oil that can be coloured with pigments. From signalling functions at road intersections to traffic flow guidance and attractive design features in gardening and landscaping scenarios, the project sites show particular highlights that, above all, can be achieved quickly and easily by the small machines.
Sustainability on small to medium-sized construction sites: zero oprating emission construction
The already strict stipulations in calls for tender for municipal construction projects in urban settings are becoming more and more stringent. At the same time, potential investors are increasingly demanding sustainable project realisation as a proviso for project financing, and more and more construction contractors themselves are actively pursuing their own sustainability goals. For the first time, the modular concept from the Wirtgen Group offers road construction contractors an end-to-end production system that enables the achievement of future road construction projects with zero operating emissions. Solutions from a single source also mean high operational reliability and perfectly coordinated processes in all machines and telematics solutions.
The production system is based on a battery-electric drive concept that can be expanded with additional modules. In the case of the road construction machines, this is a technological proof-of-concept project involving the Wirtgen cold milling machine W 50 Re, the Vögele SUPER 1300-5e road paver, and the Hamm HX 70e tandem roller. The electrically powered machines enable the achievement of road rehabilitation projects with zero operating emissions.
The production system can also be expanded when and as required. The MULTI JET burner from Benninghoven can be fuelled exclusively with 100% green hydrogen and is the first of its kind to enable asphalt production with zero CO2 emissions. The Kleemann MR 100i NEOe mobile impact crusher enables sustainable processing of the milled material re-used in the production of the new asphalt mix in the asphalt mixing plant. Exclusively electric operation is possible thanks to the ability to connect to an external power grid. As a back-up option in the event of an inadequate local power supply, the plant can, however, also be powered with a smaller carbon footprint by a diesel-electric system using the alternative fuel HVO100.
