Product Description

The gantry seam straightening machine is professional Large Straightening Equipment independently developed for the straightness correction of long and large-diameter metal poles after seam welding. As core industrial Straightening Equipment, it focuses on solving bending, deformation and uneven straightness caused by welding stress in pole manufacturing. It serves as essential Power Pole Production Equipment, specially used for precision straightening of thick-wall power poles and transmission poles after longitudinal seam welding, ensuring the overall verticality and structural flatness of finished power poles to meet strict power engineering installation standards.

This heavy-duty Large Straightening Equipment adopts reinforced gantry frame structure and hydraulic synchronous pressure regulation system. It features uniform pressure distribution, high straightening accuracy and no secondary damage to the pole body. Different from traditional manual correction and small straightening machines, the equipment realizes integral full-length straightening for ultra-long poles, effectively eliminating welding deformation, body torsion and local bending defects. With intelligent pressure control and adjustable straightening stroke, it can adapt to various pole specifications, wall thicknesses and deformation degrees, delivering consistent and reliable calibration results.

Widely applied in municipal and power infrastructure manufacturing, it is indispensable High Mast Pole Production Equipment for large-scale high mast pole processing. It perfectly solves the straightness correction difficulties of super-long and heavy high mast poles after seam welding, greatly improving the overall yield and appearance quality of high mast products. As high-precision Straightening Equipment, dedicated Power Pole Production Equipment and professional High Mast Pole Production Equipment, it realizes standardized and efficient post-weld shaping for pole workpieces. It effectively reduces manual correction workload, avoids material waste, and ensures excellent installation accuracy and outdoor structural stability of finished poles.
