The 20 ton self-aligning welding rotator is heavy-duty welding auxiliary equipment designed for industrial applications. It automatically centers cylindrical workpieces without manual roller distance adjustment, making it ideal for circumferential welding, polishing, and assembly of pressure vessels, storage tanks, boilers, and large-diameter pipes.

The complete set includes a driving rotator, idler rotator, and electric control cabinet. Built with high-strength welded steel frames and wear-resistant PU rollers, this equipment features variable-frequency drive for stable low-speed rotation, effectively improving circular seam welding quality and working efficiency.

• Automatic self-centering structure adapts to different cylinder diameters, saving setup time
• Heavy-duty welded steel base provides strong bearing capacity and stable running under full load
• High-performance polyurethane rollers offer high friction without damaging workpiece surfaces (steel/rubber rollers optional)
• VFD stepless speed adjustment with wide speed range for smooth rotation and low noise
• Equipped with emergency stop button and overload protection for operation safety
• Control box with start-stop, speed adjustment, and forward-reverse functions (foot pedal switch optional)

• Foot pedal operation switch
• Anti-drift device for preventing workpiece axial movement
• Steel roller / rubber roller replacement
• Remote wireless control box
• Custom voltage for different countries

• Driving & Idler Frame: Heavy-duty welded steel structure with stress-relieved annealing treatment to prevent deformation under full-load conditions
• PU Roller: High-elastic polyurethane material with excellent friction coefficient that avoids scratching paint surfaces of tank shells
• VFD Speed Controller: Well-known brand frequency converter providing stable low-speed output with anti-shock during start-stop operations
• Electric Cabinet: Independent separated control box with emergency stop, forward-reverse rotation, and speed knob (Protection grade IP54)
• Self-Centering Linkage Mechanism: Mechanical four-bar linkage automatically adjusts roller opening when workpiece diameter changes, eliminating manual adjustment requirements

• Main machine packed with plastic wrap + fumigated wooden case, suitable for sea and land transportation
• Control cabinet packaged in independent plywood box to prevent collision damage
• Shipping marks can be customized according to customer requirements
• Lead time: Typically 20-25 working days after receiving deposit
