Wirtgen W100CFi: Compact Milling Machine for a Special Construction

In Austria, a Wittgen W100CFi compact milling machine with a large depth milling device is doing the work of milling grooves before laying the broadband cable – just before it starts milling off the entire road surface.

The popularity of fiber-optic cables is rapidly developing globally. The town of Sheerding in northern Austria is not far from the German border and is no exception. The community here is equipped with a broadband internet connection. Engelhartszell is the second community that has benefited from this technology. The contractor of the project was from Hemmelmair of Linz in the northern port of Austria. They also used state-of-the-art technology in this construction project. The installation consists of steel and carbide. For local road construction operations, the construction party used W100CFi, the latest generation of compact milling machines equipped with a large depth milling device, which was developed by Wirtgen for this type of construction application.

Construction Site

In the construction of the milling trenches in the northern town of Hemmelmair, Hemmelmair chose the Wirtgen compact milling machine W100CFi. This modern method of milling trenches for pipe and cable laying reduces costs while accelerating the development of fiber optic cables.

Quickly switch between milling grooves and repairing roads

“We have 15 Wirtgen cold milling machines under construction. In our long-term cooperation process, we highly valued your company’s expertise in solutions, which also prompted us to choose again in this construction project in Austria. Wirtgen Group," stated the general manager from Hemmelmair. Once the requirements are discussed with Wirtgen's product management team, the design department of the German brand headquarters will receive development orders. Manfred Stiegler, customer service manager of Wirtgen Group sales and service company in Austria, said: “We want our customers to be able to use this milling machine very flexibly, that is to switch the equipment back to conventional repair construction in the shortest possible time. status."

Economical solution

With a powerful cold planer and a custom deep-depth milling machine with a narrow milling cutter, Wirtgen offers an economical solution for the laying of broadband cables.

Milling groove solution: Wirtgen's new milling cutter

W100CFi is the ideal choice for this construction project in Austria. It is one of the new generation of Wirtgen compact milling machines that integrates many innovative new automation functions to provide users with efficient support in operating the machine and optimizing the construction process. Wirtgen has developed a special solution for the milling of grooves. The milling housing is located behind the folding track on the right side of the machine. The housing contains a narrow milling disc with a standard W6 milling head. With a large cutting diameter of 1,620 mm, the machine is capable of milling trenches up to 600 mm in depth and up to 300 mm in width. This rotary milling method transfers the milled material upwards and exits through baffles and chutes.

Once an empty pipe is laid, the adjacent surface is usually milled off.
Then cover the ditch with a brand new bituminous layer.

This large depth milling device is controlled by the W100CFi's conventional control panel. "This means that the operator can manipulate the milling machine in the usual way," explains Andreas Salz, who is responsible for cutting technology design and development.

General and special construction applications

The general manager of Hemmelmair was impressed by the solution of Wirtgen groove milling on the spot: “The depth milling device is easy to install and remove, and the W100CFi can also be directly transported, which ensures that we can use this milling in a flexible and efficient manner. "This is the reason why the Wirtgen equipment was selected for this construction project in Austria: Shortly after the trench milling operation, the W100CFi compact milling machine was used for the repair of country roads. Here, W100CFi is satisfied with its economic efficiency. In this case, the universal milling system plays a major role.

Universal Milling System (FCS): More widely used

The Wirtgen Universal Milling System, abbreviated as FCS, offers the best solution for high machine utilization: milling drums with different tool pitches or working widths can be replaced in a very short time. Depending on the machine, the time required to change the milling drum is also different, but it only takes 0.5 to 1.5 hours - for example, the cold milling machine is modified from the standard type to the fine milling. Use finish milling drums to remove grooves in country roads, prepare a driveway for thin finishes or use ultra-fine milling drums to remove asphalt coating or concrete pavement - all of these construction projects can use a Witt Root W100CFi cold milling machine is easy to implement. The wide range of work of FCS milling drums broadens the range of applications for cold milling machines. (This article is from Wirtgen)
