The riddling bucket works with the same hydraulic system as the rockbreaker or the grab and is designed to be fitted on diggers from 2,5 to 40 tonnes.

It has an extremely wide field of applications ranging from the selection of pebbles along watercourses, the construction of retaining structures, selection of materials resulting from demolition, reclamation of stony ground and removal of stones along beaches. These applications are obtained by the use of interchangeable baskets.

The riddling bucket has been proved to be 10 times more efficient than a normal bucket with grille.
