Gm 180 AF

Our new trencher GM 180 AF, even more power for fiber optic expansion

As a new member of our repertoire, the GM 180 AF for fiber optic extension represents the new top model of our add-on cutters, replacing the 160 AF from its throne. The 180 AF is characterized above all by even more power when milling, which is required above all when milling in rock. Likewise, a milling depth of up to 2 meters is possible. Their areas of application are thus almost unlimited, as both fine work on a roadside and hard work such as rock milling are possible with one machine.

Information on the GM 180 AF trencher

Despite its power, the GM 180 AF for fiber optic expansion is comparatively light. With a weight of just 4500 Kg, the GM 180 AF can be easily mounted on a 300 HP tractor. The carrier should have a weight of approx. 10 tons in order to be able to operate the machine reasonably. The hydraulic power of the tractor is not very important, because the trencher is mechanically driven by a PTO. Only for lifting and lowering as well as for driving the conveyor belt a hydraulic power of the tractor must be given, however, for this a power of 60 liters at 180 bar is sufficient, which corresponds to the standard value of most tractors.

A major advantage of the GM 180 AF in fiberglass removal is the aforementioned mechanical chain drive. This ensures that considerably more power can be called up, whereby the tractor does not have to take on any effort, as it does not have to drive the chain hydraulically. This technology distinguishes us from many other manufacturers and brings great advantages. On the one hand, the already mentioned independence from the tug. Since the chain drive is not hydraulically driven, there is no loss of power due to lack of hydraulic power.

Why fiber optic expansion with the trencher?

In fiberglass construction, accuracy and precision are key. If the trenches are not dug properly, the empty conduits cannot be laid properly and the fiber optic cables also cannot be pulled through the empty conduit as intended. In the end, the trench often has to be reopened to get everything back out and do it again. This does not have much to do with efficiency, as money and time are wasted. But that can also be done differently!

How? with the trencher! In contrast to the excavator, work here is much more precise and faster. Trenches can be pulled not only faster, but also cleaner. The trencher cuts through the earth like a knife. The trenches are then free of stones or the like so that the empty pipes can be laid professionally. This will save you money at the end of the day.

Again and again excavators are used for fiber optic work on the grounds that they would be cheaper. This is often the case in the acquisition, but the calculation often does not work out as expected. Due to problems already mentioned, such as unclean trenches, laying work often has to be done twice. This costs an extremely large amount of time and, above all, money. This money and the stress associated with it can be avoided by working with a trencher already at the beginning.

Many of our customers previously worked with excavators and today can no longer imagine working without a trencher. Due to the extreme advantages and the versatile application possibilities, a trencher belongs to every construction company. Because there is no room for lost time and money in the construction industry.
