The RGP riddle 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.
Features
Main features:
- Based on GP bucket
- Steel rods on bottom

About this family
This riddle 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.

More from this family group
SGP Heavy duty skeleton GP bucket
Built on the GP bucket, with a bottom of S355 steel ribs instead of a closed plate. Fine soil and water fall through, and stones, roots and rubble stay in the bucket.
GPO GP bucket with perforated bottom
Holes cut in the bottom let soil fall through while stones stay in the bucket. A mini or midi excavator sorts stone from soil as it digs.
RGPL Skeleton rod GPL bucket
Built on the GPL bucket, with a bent top section for digging and a recessed bracket as an option. A mini-excavator separates material and cleans up with it.
GPLO GPL bucket with perforated bottom
The bottom plate has holes cut in it, so fine soil, sand and water fall through while stones and roots stay in. You dig and screen in the same pass.
SGPL Heavy duty skeleton GPL bucket for mini-excavator
Built on the GPL bucket, with S355 steel ribs in the bottom instead of a closed plate. A mini or midi excavator separates fine soil and water from stones, roots and rubble in the same pass.
PDP mini - skeleton BDP stone bucket
Riddle bucket for mini and midi excavators, built heavier than a general-purpose bucket. It sieves on site and handles demolition, excavation and loading.
