drum cutter with cutter wheel or wheel cutter

By: Drumcutters  06-Dec-2011

Cutting short lengths of narrow, shallow trenches in hard material can be a problem especially when the length of trench does not justify the use of a full scale trenching machine.  Drum cutters fitted with a wheel cutter provide an alternative solution and under the right circumstances can be extremely cost effective.

The full range of transverse drum cutters can be supplied with wheel cutters, dimensions are as follows:

  • ER 100   Max wheel dia 650 mm, max cutting depth 210 mm
  • ER 250   Max wheel dia 750 mm, max cutting depth 240 mm
  • ER 600   Max wheel dia 850 mm, max cutting depth 250 mm

Auger drive units - Drumcutters

Owners asked whether their longitudinal drum cutters could be used as rotary heads so Erkat designed an adaptor that could be attached to the output shaft for this purpose. Although extremely useful for some applications, the standard longutidinal drum cutter plus adaptor was too long and too expensive for use as a dedicated auger drive unit.
