The GKB mini is a narrow, deep bucket for digging cable trenches with a mini or midi excavator. Three sizes cover machines from 1.0 to 12 t: GKB-30 (1.0 to 3.0 t) and GKB-60 (3.0 to 6.0 t) are 150 mm wide, GKB-120 (6.0 to 12 t) is 200 mm wide.
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 heavy-duty 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.
Features
- Digging depth: made for digging deep trenches.
- Rugged Construction: Built with high-strength steel so it lasts in hard excavation work.
- Narrow Bucket Profile: Cuts a narrow trench and takes out less soil.
Optional features:
- Heavy-Duty Wear Plates: For work in abrasive soil.
