The W 50 DC is the most powerful small milling machine in the half-metre class currently in the market. A large variety of options enable a broad range of flexible applications and guarantee optimum utilization of the machine.
When repairing partial damages in road pavements, the machine operator can control the milling depth, as well as the longitudinal and cross slope of the milled surface with pin-point accuracy. The machine produces a clean, straight and smooth milling edge. The texture of the milled surface permits an excellent bond between the existing base and the new pavement material.
Wheel ruts, pronounced bumps or other kinds of deformation are potential risks to traffic safety. They can be eliminated very quickly by using cold milling machines equipped with specific fine milling drums. This method simply mills off the elevated sections of the road pavement, leaving behind an even and skid-resistant surface that can be used by traffic immediately.
Replacing the surface course at milling depths of up to 4 cm is a typical application in road rehabilitation. In these projects, small milling machines are often used in combination with large milling machines: The small machines work in narrow passages, peripheral areas and around road fixtures, while the large machines mill off the large surfaces.
Small milling machines are eminently suitable for removing the pavement around manhole covers at a precisely specified depth, exposing the cover after one single “lap”.
The W 50 DC’s extremely small turning radius and design with one zero side promote this fast and highly precise method that permits milling right up to the edge of road fixtures, eliminating the need for manual reworking.
The W 50 DC is eminently suitable for milling pavements in trench construction. In contrast to breaking the pavement with hydraulic hammers, the milled material can remain in the trench and can be used by traffic temporarily after light compaction. Disruptions to traffic are thus minimized.
The W 50 DC can be fitted with a narrow slot cutting ring or side cutting ring, enabling it to cut slots along a trench to be excavated. A significantly higher performance can be achieved at significantly lower tool costs when compared to cutting slots with a joint cutter.
Prior to placing a new pavement, tie-ins to the existing pavement are produced at the beginning and at the end of the newly paved section of road. Milling wedged tie-ins permits a level transition to be produced when placing the new pavement material.
The same applies wherever rehabilitated pavements need to be placed to a specified level, for instance, with water gutters or rainwater inlets.
The W 50 DC is capable of milling the asphalt surface at precisely the required depth and in the specified contour for the construction of traffic islands. The exceptionally manoeuvrable 3-wheeled machine enables the design of interesting geometric shapes.
Small milling machines are eminently suitable for the fast removal of asphalt surfaces in or around industrial buildings that are either contaminated or in need of rehabilitation. Special preparations are not required. Milling in layers enables the small milling machine to precisely separate contaminated and non-contaminated material.
Fine milling drums are fitted with a much larger number of cutting tools than standard milling drums, which results in a much narrower tool spacing. Fine milling produces a very fine surface texture and is carried out at maximum milling depths of just a few millimetres or centimetres.
