Correct cable laying of optical fibre

Glass fibre – with high speed into the future

The future belongs to glass fibre. Data can be transmitted much faster than with copper. Today, not only the Internet, but also radio, TV, telephone and much more come through these fibres. No wonder, then, that laying fibre optic cables is currently a much sought-after job. These cable installations are carried out in the middle of the countryside as well as in villages and towns along the Inn. If you intend to do such work, you have come to the right place!

Laying underground cables with the GM4 Allrad – save time and money

The trenchers of the GM 4 all-wheel drive series are diesel driven and self-propelled all-wheel drive trenchers. They have a low dead weight and thus guarantee a low ground load. The tilt device can easily compensate for lateral slopes of up to 15 degrees, which is a great help especially in hilly regions.

The excavated material is ejected either to the right or left. However, the conveyor belt can be inserted on both sides so that the excavated material can also be loaded directly. Due to the additional filling funnel, milling and filling with gravel is realised in only one operation. Further accessories enable the GM 4 all-wheel drive trenchers to directly pull in cables and pipes. This means that milling, laying and backfilling can then be carried out in a single operation. This saves a lot of time, which also means that the construction site can be completed more quickly. In addition, the all-wheel milling machines can also be equipped with twin tyres. This provides even better grip and stability, which can be particularly important in rural areas.


With the self-propelled machine, trenches can be cut without any problems, even in hard ground. For example in asphalt. Especially our GM4 is often used for work in the city. Due to its low weight and the high mobility of the GM4 it is ideal for urban work. These trenchers are indispensable tools for cable laying, both in the country and in the city.

Moving into the future – glass fibre

A special milling machine can in many cases replace the excavator. The reason for this is the speed at which such a milling machine works. The work that such a milling machine can do in an hour is hardly possible with an excavator. However, many people do not even know that it is possible to work with a trencher. Some people only want to dig small trenches and do not want to invest in a trencher. However, it is clearly more efficient and environmentally friendly.

But if you look a little bit into the future, you can see that fibreglass will be a big undertaking for some years to come. Finite cables still have to be laid to build up a stable network. For this reason, the investment in a trench cutting machine is worthwhile. Apart from the efficiency of such a machine, our machines also meet all environmental standards. So you can look into the future with confidence, knowing that you are up to date.

When it comes to successful cable laying, the word “micro-trenching” is often used. This describes a type of milling in which only a narrow gap is cut into the ground. This is quicker because the gap is very small, as already mentioned, and the work can therefore be carried out more quickly. Especially in the cities a lot is relied on this technique. You can find further information here!

By the way, there are several trenching methods, namely micro, mini and macro trenching. These differ in the depth and width of the realised milling slots and in the cutting or milling technology used.

Laying underground cables with an ecological footprint

The extremely environmentally friendly alternative to the excavator guarantees a maximum workload for cable laying without major impairments in terms of the Nature Conservation Act. A central focus of activity in construction is the laying of fibre optic cables in various design variants. The services of the all-rounder include not only the construction of cable trenches, but also the environmentally friendly excavation of the ground. The individual equipment of our trenching machines is available on request.

Construction and cable laying in a fast procedure. Thanks to the latest technology and processes, the fibre optic cables are laid underground within a very short time. Small excavated trenches of minimised width are usually closed again the same day. In many cases, civil engineering work can even be dispensed with altogether, as empty conduits for the fibre optic cables can be pulled through under the pavement using, among other methods, the flush drilling method. In this way, disturbances for the residents are also kept to a minimum.
