Description
Self-Aligning 20 Ton Welding Rotator for Wind Tower and Storage Tank Production
Product Overview

This self-aligning welding rotator is engineered for heavy cylindrical workpieces in pressure-vessel and tank workshops. Roller sets automatically adjust angles to match shell diameter without manual repositioning. The heavy-duty base and PU roller assembly deliver steady circumferential rotation, eliminating workpiece slipping and bounce during long production shifts. Works well paired with column-boom welding systems for seamless automatic circumferential seam welding.

Key Features
  • Self-aligning roller structure automatically adjusts to fit different shell diameters, saving manual adjustment time
  • Thick welded base frame with dual-motor driving unit and frequency converter provides stable low-speed torque for heavy shell rotation
  • High-strength PU covered rollers with high friction coefficient protect outer surfaces of carbon steel and stainless-steel shells
  • Continuous stepless speed regulation matches rotation speed to welding travel speed for consistent circumferential weld quality
  • Built-in overload protection and emergency stop function with reserved signal interface to synchronize with welding manipulator

Frequently Asked Questions
What diameter range of cylindrical shells can this 20 ton self-aligning welding rotator handle?
Suitable for workpiece diameter from 500 mm to 4500 mm. Rollers adjust automatically without manual modification.
Is continuous full-load operation available for tank mass production?
Yes. Reinforced frame and dual-motor drive support long-time non-stop heavy-load running in-house.
Can this rotator work synchronously with column-boom welding manipulator?
Synchronous signal interface is reserved, it can realize linkage with welding manipulator for automatic circular seam welding.
What should I do if the cylindrical shell is too long and prone to deflection?
Extra auxiliary idler units can be added to provide extra support and avoid shell bending and deformation.
Can I change PU rollers into steel rollers for special working conditions?
Steel roller is available as custom option for high-temperature or sharp-surface workpiece welding scenarios.
