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.
Features
- Digging depth: made for digging deep trenches.
- Material: high-strength steel, for hard excavation work.
- Narrow Bucket Profile: Cuts a narrow trench and takes out less soil.
Optional features:
- Wear Plates: For work in abrasive soil.

Which coupler is on your machine?
Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.
How to measure your coupler
Not sure which system it is? Three measurements tell us which bracket you need.
- Measure the diameter of both pins.
- Measure the distance between the pin centres.
- Measure the width between the inside faces of the ears.
If the coupler has a make or type printed on it, send that too.
