XXZ12 BOX BEAM ASSMEBLING MACHINE According to the processing features and requirement of box beam, the cover plates of 4 sides must be connected tightly with the internal reinforcing plates to avoid the out-flowing of slag liquid when doing electro-slag welding. At same time the internal reinforcing plates inside the whole piece of box beam are discontinuousness, so our company developed this movable gantry type box-beam assembling machine. This machine is the important equipment for the box-beam production, mainly used in the assembling of box-beam.
