Product Description
20 Ton Self-Aligning Tank Turning Rolls for Pressure Vessel & Boiler Welding
Product Overview
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.
Main Features
- 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)

Frequently Asked Questions
What is the maximum weight this 20 ton self-aligning welding rotator can bear?
Rated load capacity is 20 tons. Ensure the total weight of your cylindrical workpiece does not exceed 20 tons for safe operation.
What range of workpiece diameter can this set handle?
Standard applicable workpiece diameter is 500-3500 mm. Non-standard diameter ranges can be customized upon request.
Does this rotator need manual adjustment when changing different tank diameters?
No. The four-bar linkage self-centering structure automatically adjusts roller spacing for different-diameter cylinders without manual setting.
Can I add extra idler units for extra-long pressure vessels?
Yes. Additional idler roller units can be supplied to support long-length workpieces and prevent workpiece sagging.
What kind of roller options are available?
Standard roller is polyurethane PU wheel. Steel roller and rubber roller are optional for special working conditions.
Can you provide CE certificate? What about documents for Kazakhstan / Russia market?
CE certificate is available. For CIS countries, we can provide supporting documents for EAC declaration to meet local customs clearance requirements.
