GM 140 H excavator attachment trencher

Trencher GM 140 H for excavator

The GM 140 H trencher from Lingener Baumaschinen is a powerful excavator-mounted trencher designed for use on excavators. It is particularly suitable for use on construction sites where major trenching work has to be carried out.

The GM 140 H is mounted on an excavator and operated by the excavator hydraulics. The excavator-mounted trencher has a robust cutter head that can mill through hard soil layers to create wider and deeper trenches.

The machine is equipped with a hydraulic system that allows quick and easy adjustment of the milling depth. This allows the machine to be quickly adapted to different soil conditions.

The GM 140 H is also equipped with a special protection system that prevents the milling head from penetrating too deeply into the ground and damaging the cutting tools. This is particularly important to ensure a long service life of the machine.

In addition, the GM 140 H has a filling device that transports the excavated material directly into a trailer or container. This allows the excavation material to be removed quickly and easily.

Overall, the GM 140 H excavator-mounted trencher from Lingener Baumaschinen is a robust and reliable machine that is ideal for use on larger construction sites. It is easy to use and can be quickly adapted to the requirements of different projects.

Combining the GM 140 H trencher with an excavator

Among many other factors, the right tools and machines play a crucial role in Germany’s digital expansion. In order to supply the entire republic with fast Internet, it is necessary to lay large quantities of fiber optic cables underground. This is where the GM 140 H excavator-mounted trencher comes into play. With this trencher for excavators it is possible to cut suitable trenches for laying such cables quickly and with little effort. Furthermore, such a device helps to lay drainage pipes and other types of pipes.

The large operating radius of the GM 140 H excavator-mounted trencher

An immense advantage of this excavator-mounted trencher is that it can be combined with a hydraulic excavator. This gives it an immensely large radius of action. Because of the mobility and power of the excavator, such a cultivator can be used to cut many and deep trenches in a very short time. Likewise, obstacles are no longer a problem, as the excavator can simply work over them. For these reasons, this tiller is a very good alternative to self-propelled tillers. Mounting the tiller proves to be as simple as can be and yet it holds very stably on the excavator.

The GM 140 H excavator-mounted trencher in use

Once mounted on a hydraulic excavator, the GM 140 H excavator-mounted trencher can be used in almost any direction. This means, for example, that it can work parallel to the direction of travel. This is a clear advantage over classic variants that are towed by a tractor. In addition, the trenches created by this trencher are decidedly narrow and precise. Thus, no more soil is dug up than absolutely necessary.

The excavator attachment deposits the excavated material on both sides of the trench by means of two augers. Thus, the earth can not slide down again by itself, and yet after laying the cable is easy to backfill the trench. Because of this efficient mode of operation, the GM 140 H excavator-mounted trencher is very popular among companies. It reduces the amount of work to a minimum and is therefore very economical.

Possible equipment variants of the GM 140 H excavator-mounted trencher

Precision is key when milling trenches. That is why it is advisable not to use just any tool, but one that is perfect for the task at hand. In this context, it is very convenient that there are different equipment variants for the GM 140 H excavator-mounted trencher. For example, it is possible to use different milling beams, each with its own dimensions. Smaller versions with 600 or 850 millimeters are available, as are larger versions with 1,200 or 1,500 millimeters.

Models with different chain widths between 125-500 millimeters on the first beam and 500 or 600 millimeters on the second beam are also available. Many users also rave about sole scraper with sole plate of such a milling machine, which can adjust to the respective milling depth both mechanically and automatically. Likewise, a depth control by laser is possible and also a pipe laying shaft and various cable reel holders are part of the possible equipment of a trencher for excavators.
