Pilemaster III pile cage machine will weld automatically not only round pile cages, but the welding of square, rectangular and triangular cages. The welding is precise by a flexible welding head and through an integrated bar support, which follows the curve of the polygonal cage easily. This new generation of machine comes with the new ring discs system to allow the production of individual cage diameters. The control unit will check the quality of the actual welding and in case of failure.
