Pure innovation! The ETR range of chain saw trenchers opens up a completely new range of opportunities for excavators. For the first time, a trenching attachment for excavators that is not limited to working in soils but can work in rock with a compressive strength of up to 90 Mpa (ETR 3).The ETR trencher can produce straight trenches with perfect profiles in widths from 30 to 60 centimeters to a maximum depth of 2.5 meters.
