Effortlessly complete heavy milling jobs with the GM 300-H depth milling machine

A depth milling machine is particularly suitable for large projects that require a considerable working depth. This machine creates deep and wide trenches that are characterized by their cleanliness and precision. The GM 300-H trench milling machine is particularly efficient. This depth milling machine is connected to a tractor by means of a three-point linkage and performs work effortlessly in a very short time, for which people would have to invest a great deal of time and energy. Many industrial companies swear by this trench cutting machine with its high-quality milling chains.

Working quickly and efficiently with the GM 300-H depth milling machine

The trench milling machine GM 300-H is a depth milling machine which is particularly suitable for demanding and complex milling work. Within a very short time, this machine can be used to create long trenches with a depth of 600-1,700 millimeters and widths of 150-600 millimeters. Even large pipes can be buried in this way without great effort. One of the reasons for the high efficiency of the milling machine is its hydraulic track drive. The 6-cylinder turbo diesel delivers 145 kW or 195 HP and is therefore very powerful.

Flexible milling chains for the respective soil and condition

Another strength of the GM 300-H trench cutting machine is its milling chains. It is so flexible that it can work with very different chains. In this way it is possible to adapt the implement individually to the respective soil and the nature of the workplace. It is important to use a tractor with a three-point linkage and high strength. Only then can the depth milling machine be effortlessly attached and used. Because its own weight of 16,000 kg is already very considerable.

Important facts about the GM 300-H depth milling machine

The transverse inclination of the cutter bar can be individually adjusted on the GM 300-H trench cutting machine. It is also possible to use the cutter bar hydraulically offset from the side. Up to 60 cm above the outer edge of the machine is possible. Additional flexibility is provided by the cab, which can be swivelled hydraulically. This means that the working radius can be adjusted and the milling work can be carried out particularly easily by hand. The hydraulic caterpillar drive permits good movement on various surfaces and ensures stability and stability during work. On request, it is also possible to use quick-change rubber adapter plates with the machine.

Using the depth milling machine with the hydraulic conveyor belt

The hydraulic conveyor belt is very practical when using the depth milling machine. This applies regardless of which milling chains the machine is equipped with. With this conveyor belt, the excavated material can be deposited on the right or left side of the trench as required and can be easily reused for backfilling after laying the pipe or other work. Many companies also swear by a loading conveyor belt, which enables front loading onto a truck. Such a belt can be purchased as an option to the depth milling machine.

Individual expansion of the GM 300-H depth milling machine

Even in its standard version, the GM 300-H trench cutting machine offers a lot of power and can be used flexibly. In some cases, however, it is necessary to adapt the machine to one's own needs or to the requirements of a construction project. A large number of optional accessories are available for this purpose. For example, it is possible to opt for a cabin with heating and air conditioning. In this case, the milling machine can be used in almost all weather conditions. For maximum efficiency, it must be ensured that the milling machine is reliably connected to the tractor via the three-point linkage.

Another option is to work with a backfilling auger or a dozer blade. These facilitate the use of the GM 300-H trench cutting machine enormously. The cable drum holder and the laser system for depth control are also extremely helpful in everyday work. Last but not least, there are various milling chains and coils for drain pipes to choose from, with which the depth milling machine can be equipped. With the right selection of accessories, the milling machine adapts itself as well as possible to the respective working environment and thus performs excellent services.
