Grabbing crane

An item of machinery comprising two pieces which, adapted to public works machinery, facilitate drilling and extraction of material stored at certain depths, as well as its subsequent removal to a container. It functions electro-hydraulically, via cylinders that activate opening and closing of the valves, in such a way that the excavated material is simultaneously compressed and dehydrated. The valves usually include drainage outlets, allowing for reduction in wetness of solids retained. It is suitable for working on excavation of wells and watercourses, with stone, sand, mud and sludge with density of below 2.2 t/m3.
