About this family
The GKB deep cable bucket digs deep, narrow cable trenches with a mini-excavator. It is 150 or 200 mm wide, so only a narrow strip of the site is opened.
The bucket is 715, 832 or 1000 mm high and weighs 37, 47 or 79 kg. It is built from high-strength steel, and wear plates are available as an option for abrasive soil. S, MS, M, HS, CW, OQ and Klac brackets are listed for every size, for example CW05 on GKB-30 and CW10 on GKB-60 and GKB-120.
