Drainage work can be carried out very well with the GM 1800 P trench milling machine.

Both in house building and in agriculture, drainage work is of paramount importance. Rainwater and other moisture must be drained reliably to avoid long-term damage. Drainage pipes are a good choice. They must be laid underground so that they can absorb and drain the arising water well. This task is performed by high-quality drainage machines such as the GM 1800 P trench cutting machine from Grabenmeister. Numerous companies are already convinced of the reliability and efficiency of a trench cutting machine for drainage.

Using the GM 1800 P trench milling machine for drainage work

The GM 1800 P trench milling machine has already proven itself in numerous drainage applications. The trencher for drainage reaches a ploughing depth of up to 1,800 millimetres and thus creates deep, clean and precise trenches. However, it is more than just a drainage machine and is therefore also suitable for laying cables or gas and water pipes. The machine benefits from its 6-cylinder turbo diesel engine, which generates 400 hp or 294.2 kW and thus provides plenty of power and performance. With such drainage machines, it only takes a very short time to mill a large number of trenches or a very long trench.

One strength of such drainage machines is their hydraulic steering. Thanks to this, drainage work can be carried out very flexibly and adapted to the respective soil and environmental conditions. The caterpillar running gear of the drainage machines proves to be extremely helpful here. This works with a fully hydrostatic travel drive, which ensures the greatest possible flexibility in operation. This enables the machine operators to adjust the track width of the trench cutting machine for drainage from 2.70 to 4 metres during operation.

Possible equipment features of a trench milling machine for drainages

Drainage machines such as the GM 1800 P trenchers usually have a hydraulic system in which all functions can be controlled via the control panel. A 2,700 millimetre chassis is standard, but can be extended hydraulically to up to 4,000 millimetres on request. A laser system can also be used to adjust the depth. The equipment also includes a cable drum holder and GPS control with recording. The caterpillar drive is controlled via a joystick.

It is advisable to select the trench cutting machine's equipment for drainage in such a way that it suits the respective project and soil. For example, a side-shifted plough blade can be used as required. The better the drainage machines are tailored to their field of application, the faster and more efficient the work will be. Another very practical feature for drainage work is that the working and transport speed of the trench cutting machine can be variably set between 0-5 km/h for drainage work.

Use of the GM 1800 P trench cutting machine

Before using a trench milling machine for drainage, it should be remembered that the GM 1800 P trench milling machine has a dead weight of 30,000 kg. The area of application must be suitable for such a heavy machine. The equipment used plays a role here. If additional elements are used together with the drainage machines, their weight increases significantly. The plough depth is also a decisive factor when selecting a suitable trench cutting machine. This is one of the factors that determines whether a tiller is suitable for a particular project.

A trench cultivator for drainage is used in a wide variety of weather conditions. It is therefore pleasant that the comfort cab has both a heating and air conditioning system. In this way, the machine operators always work in the most pleasant conditions possible and can concentrate fully on their task. On request, the cab can be fitted with air suspension or a particularly wide window front. The GM 1800 P trencher is also one of the drainage machines suitable for drainage pipes with a diameter of 50-160 millimetres.
