Description
20Ton Self-Aligning Welding Rotator Heavy Load PU Roller VFD Turning Rolls for Tank Vessel Welding
Product Overview

The HGZ-20 self-aligning welding rotator is specifically designed for 20-ton heavy cylindrical workpieces, ideal for circumferential seam welding of large storage tanks, pressure vessels, boiler barrels, and chemical pipelines.

The gravity linkage structure enables automatic roller spacing adjustment, eliminating manual adjustments when changing workpiece diameters. Variable frequency stepless speed control ensures stable rotation, improves circular weld formation, and reduces welding deformation.

Key Features & Advantages
  • Automatic Gravity Centering: Rollers automatically adapt to workpiece diameter, reducing downtime for frequent product switching.
  • VFD Synchronous Drive System: Dual motor synchronous drive ensures steady rotating speed suitable for automatic submerged arc welding.
  • Wear-resistant Polyurethane Rollers: Soft contact roller surface effectively protects stainless steel and anti-corrosion tank outer walls.
  • Reinforced Integral Base: Stress-relief thick steel frame provides anti-shock and anti-deformation performance under 20-ton full load.
  • Dual Operation Control: Fixed cabinet control matched with handheld remote enables safe operation away from welding high temperature zones.
  • Comprehensive Safety Protection: Emergency stop button and overload protection circuit prevent equipment damage from improper operation.
