Ironworker machines play an indispensable role in power transmission tower manufacturing, where lattice structures composed of thousands of angle iron components require extensive punching and shearing operations before assembly. A typical 500-kilovolt transmission tower contains 800 to 1,200 individual angle members, each requiring precisely punched holes for bolted connections and accurately sheared ends for fit-up with adjacent components. The punching station processes hole patterns in both legs of angle iron simultaneously using specialized tooling, with hole diameters ranging from 12 to 24 millimeters depending on bolt specifications and structural requirements. Angle shearing prepares member ends at both 90-degree and 45-degree configurations, with 45-degree mitre cuts essential for diagonal bracing members intersecting at tower corners. Notching creates clearance cuts where angle sections overlap, ensuring proper fit-up without interference that would prevent bolt installation. For heavy-angle members used in tower base sections, 100-ton to 125-ton ironworkers provide the punching force required for larger hole diameters and thicker material sections. The combination of all required operations on a single machine platform allows tower fabricators to process components in a continuous workflow, reducing handling time and improving consistency across the thousands of parts required for each tower. Power transmission and distribution infrastructure investment continues to drive demand for tower manufacturing capacity, with ironworker machines providing the fabrication backbone for this essential industry. Our ironworker machines are used by tower manufacturers globally for processing angle iron sections up to 6 inches by 6 inches by 0.5 inch thickness.
