20 Ton Self-Aligning PU Roller Welding Rotator for Tank Vessel Fabrication
Product Overview
This heavy-duty 20-ton self-aligning welding rotator is designed for cylindrical workpieces in industrial fabrication. It automatically adjusts roller angles to accommodate various tank and pipe diameters without manual intervention. Equipped with high-density PU rollers and VFD stepless speed control, it provides stable, low-noise rotation for pressure vessel, boiler, and storage-tank girth welding while protecting thin-wall and stainless surfaces from scratches.
Core Features
Automatic self-centering roller structure adapts quickly to varied workpiece diameters, reducing setup time
High-density PU rollers prevent scratching on stainless steel and thin-wall shells with excellent wear resistance
Heavy-duty welded steel frame provides strong bearing capacity and long service life for demanding fabrication workshops
Wired pendant control box for simple operation with customizable local 3-phase voltage options
Synchronization interface reserved for integration with column-boom welding manipulators
