KEMROC KRD Range of Rotary Drum Cutters
KRD Range of rotary drum cutters with direct drive feature high power to weight ratio
KRD RANGE - ROTARY DRUM CUTTERS
The new KRD range of direct drive drum cutters can be described as compact, lightweight but strong.
Lighter and shorter, these attachments are ideal for use on long-arm excavators for demolition and shaft sinking applications. They can also be used for soil stabilisation and concrete renovation applications. Intentionally oversized bearings have been used to support the cutter drums for a long operating life.
