The excavator-mounted trencher GM 160 AS is characterized by great precision

Precision is particularly important when milling trenches. The trenches must be milled as cleanly and accurately as possible to accommodate a drainage pipe without difficulty. That is why it is important to choose a high-quality cultivator for Unimog. This Excavator-mounted trencher is able to mill both large trenches and many small trenches in a very short time. Such machines are therefore used both in private house construction and on professional construction sites. The GM 160 AS trencher has already proven itself in various construction projects and has convinced with its strength and reliability.

The high precision of the Excavator mounted trencher for Unimog among other things by the carbon chisel chains and mixing chains it uses. The chain widths vary between 150-450 millimeters and are characterized by excellent workmanship and high stability. The milling beam depth is 1,250 or 1,600 millimeters. Another very useful tool is the sole scraper with sole plate, which can be adjusted mechanically or automatically to the respective milling depth.

These tasks are performed by a mounted tiller for Unimog

A mounted trencher for Unimog is particularly suitable for laying cables, pipes and drainage pipes. They therefore play a crucial role in house and road construction, but are also used in agriculture. Here, for example, drainage pipes are laid in fields to prevent backwater and the resulting damage. Thanks to the trenches neatly milled by the GM 160 AS trencher, it is easy to place the appropriate pipes in the ground. In this case, the excavated material is stored next to the trenches in such a practical way that subsequent backfilling is not a problem at all.

Depending on requirements, a milling beam depth of 1,250 millimeters or 1,600 millimeters is available. The beams can be used laterally offset, which makes working on obstacles noticeably easier. In addition, different chain widths with a size of 150-450 millimeters can be used. This results in the greatest possible individualization, so that the attachment tiller for Unimog can be used in numerous projects and for diverse substrates. A further contribution to this flexibility is made by a laser system for manual or automatic depth adjustment.
