Trenching attachments for soils and soft rock

The ETS range of trenchers can be used for producing clean, correctly profiled trenches quickly in cohesive soils as well as in soft rocks with uniaxial compressive strengths up to a maximum of 20 MPa.

The cutter chain can be fitted with tungsten carbide tipped tools for soft rock or with tools designed for use in soils. In mixed ground, cutter chains with mixed tooling have given good results.

Trenchers are designed for use on excavators from 2.5 to 10 tons and can be mounted on skid steer loaders with a suitable adaptor bracket.

  • Accurate, clean trenches to depths of 1.5 m
  • Easy to alter cutting width by changing cutter teeth
  • Cutting depths vary according to model
  • Transporting auger to clean soil out of trench
  • Trench cleaner to suit all trench widths
  • Mountable on skid steer loaders
