European style underslung crane | underslung overhead crane

European single girder underslung crane is a light duty material handling overhead crane which can be installed on the roof of the workplace without bracket, saving space and lowering cost. The trolley is small and loads can be lifted to the place as near as possible to the wall of the workplace. The traveling range of trolley can exceed crane span trough side jib. The lifting capacity of European single girder underslung crane is 1 to 20 ton and the working class is A5. The main parameters of European single girder underslung crane is shown for your reference in the following table. Customized underslung crane is available.
