The grab overhead crane for garbage generally uses double beam structure, by the opening and closing mechanism, lifting mechanism and large, small operation mechanism, etc., using six-lobe grab, the maximum lifting weight of 20 tons (including the grab weight). Grab overhead crane for garbage is the core equipment of the garbage feeding system of various garbage incineration power plants in modern cities. It is located above the garbage storage pit and mainly undertakes the operation of garbage feeding, handling, mixing, fetching and weighing.
