Skyhook positioner (also known as L-type hanging welding positioner) is a robotic 2-axis / 3-axis synchronized welding positioning device. Featuring a cantilever suspended workpiece structure, it provides full accessibility to bottom, back and inner weld seams without base interference. Widely used for engineering machinery frames, box structures, vehicle chassis and robotic welding cell automation.
