The SDB is a skeleton version of the DB digging bucket. Rods take the place of the solid bottom, so soil falls through while stone, rubble and roots stay in the bucket.
About this family
SDB skeleton bucket: a digging bucket with steel ribs that let fine material fall through as you dig.
The SDB skeleton bucket digs and sifts in one pass: interlocking steel ribs sift and separate the material while you dig. It is used for trenching, drainage work and pipe bedding.
The sorting happens as you dig, which is why it is used for trenching, drainage and pipe bedding: the fines go back in the trench and the stone goes on the heap. Six sizes cover machines from 10 to 50 t, SDB-120 through SDB-500, in widths from 1000 to 2000 mm and weights from 286 to 2172 kg.
Rods are C45 as standard and Hardox® on request, and the spacing is built to the material you sort. Teeth come in the CAT J series, BYG Futura and ESCO UltraLok systems.
Features
- Interlocking Ribs for Sifting and Separating Material
- Soil falls through as you dig, so there is less sorting afterwards
- HB500 cutting edge for digging and sorting material
- Available in Various Rib Spacings for Diverse Materials
- Hardox® rods option; C45 rods standard
- Available teeth systems: CAT J series, BYG Futura, ESCO UltraLok

Typical jobs
The SDB full-size skeleton bucket for excavators is used for:
- Construction waste sorting and processing
- Topsoil and compost screening
- Aggregate separation and grading
- Demolition material handling and sorting
- On-site material processing
- Trenching projects (utilities, drainage, foundations)
- Pipe bedding and backfilling in trenches
- Sorting out and removing debris during excavation
- Landscaping work where stones and roots are sifted out of the soil
- Jobs where the same bucket digs, sifts and sorts the material
On the SDB skeleton bucket the rib spacing decides what falls through and what stays in the bucket. Tell us the material and we confirm the rib spacing.
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.
