Product Description

The gantry seam straightening machine is newly upgraded heavy-dutyLarge Straightening Equipment, specially designed to eliminate welding deformation of long and thick tubular workpieces in pole manufacturing. As core automatic Straightening Equipment, it accurately corrects linearity deviation, overall bending and local distortion caused by welding thermal stress, effectively improving the overall machining accuracy of pole products. It acts as standard Power Pole Production Equipment, widely used for post-weld straightening and finishing of various thick-wall power poles, transmission poles and grid engineering poles, ensuring each workpiece meets strict vertical tolerance and installation standards for power infrastructure projects.

This high-performance Large Straightening Equipment adopts heavy gantry integral welding structure and hydraulic servo synchronous control technology. It features strong structural rigidity, uniform pressure output and high straightening precision without damaging the pipe wall and welding seams. Compared with traditional straightening methods, the equipment realizes full-length overall calibration for ultra-long poles, achieving one-time precise shaping with stable and repeatable results. With flexible parameter adjustment, it adapts to different pole diameters, wall thicknesses and various deformation conditions, greatly improving production efficiency and product consistency in mass processing.

It serves as key professional High Mast Pole Production Equipment for manufacturing large and ultra-high mast lighting poles. It perfectly solves the technical bottleneck of difficult straightening and low yield rate for heavy high mast poles after longitudinal seam welding. As stable Straightening Equipment, high-efficiency Power Pole Production Equipment and reliable High Mast Pole Production Equipment, it optimizes the post-weld production process, reduces manual correction and secondary polishing procedures, and significantly improves the structural flatness, appearance quality and outdoor stability of finished poles, becoming an essential precision processing device for modern pole manufacturing factories.
