The RGP skeleton bucket separates soil from stone, rubble and roots in a single pass. Parallel Hardox® rods in a universal (GP) profile let fine material fall through while oversize stays in the bucket, so screening, loading and sorting happen in the same movement.
About this family
This skeleton bucket is for mini-excavators from 1.2 to 10 tons and is built on the design of our GP bucket in a compact size. The flat top fits most European bracket systems. The bottom is made with rods, ribs or a perforated plate. Teeth can be bolted, CAT, BYG or ESCO.
Rod spacing is set to the material you handle; the shell, side plates and rod anchoring are reinforced for continuous screening duty in site clearance, land reclamation and demolition sorting.
Features

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.
