Product Description
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
- VFD stepless rotation speed adjustment ensures stable operation under full-load conditions
- 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

Application Scenarios
- Pressure-vessel workshop girth seam welding
- Chemical storage tank & stainless tank manufacturing
- Boiler shell and heat-exchanger cylinder processing
- Large-diameter steel pipe circumferential welding
- Cylindrical workpiece assembling, polishing and cladding work
Working Principle
- Active-passive matching driving structure for efficient power transmission
- VFD system precisely regulates rotating speed of active roller group
- Passive rollers follow synchronously to drive cylinder workpiece at constant speed
- Self-aligning mechanical mechanism automatically adjusts roller angle for different shell radii
- Uniform force distribution prevents shaking and workpiece offset during continuous welding
- Provides steady rotating conditions for circumferential welding and surface treatment
