It is general-purpose equipment for excavation of solid ground which can be used in town development, farm building and f transportation management for making of different types of earthworks.

The AT trench opening unit is designed for:

  • trench opening so as to lay communication lines and power lines, laying of pipelines and other routes of communication;
  • works on limestone and sandstone cutting,
  • slot cutting 140 mm wide so as to loosen frozen and hard soil up to IV category and soil abrasivity of up to10 mg. (while fitting of base cutting chain 2086.01.02.060-01) for carrying out earthworks..

In addition 2086.01.02.050-03 cutting chains could be supplied with cutting slot width of 270 mm or 2086.01.02.050 chains with cutting slot width of 400 mm in soils of the II category and soil abrasivity of up to 10 mg. The above chains are to be fitted at a soil-cutter instead of a base chain without any additional alterations
