DB is for
- Digging and trenching in soil on building and utility sites
- Foundations, basements and site preparation
- Loading and moving bulk material such as soil and rubble
- A size picked from the model table, built as Economy, Standard or Heavy Duty
Choose DBF instead if
- Your excavator changes attachments on a quick coupler and a flat-top bucket suits it
Choose DSX instead if
- You dig rocky ground or abrasive material and want a Nordic profile bucket with a Hardox® body
Choose DBS instead if
- You dig rock and want the bucket designed for your machine and that rock
- Teeth, adapters, side cutters and wear protection should be chosen for your job
- You need a factory acceptance test record with the bucket

About this family
DB digging bucket for excavators from 10 to 50 t.
The DB Excavator Digging Bucket digs trenches, foundations and basements, and loads earth, rock and debris. It has a large capacity and a heavy build for hard digging, and it is matched to your excavator’s hydraulic system.
Seven sizes cover machines from 10 to 50 t, DB-120 through DB-500, in widths from 400 to 1800 mm and weights from 156 to 1829 kg. Each size is built as Economy up to 24 t, as Standard and as Heavy Duty above 24 t, and a rock version is available.

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.
