Products advantage
Self-aligning Automatic Adaptation
It can automatically adjust and match different cylinder diameters without manual roller spacing adjustment, saving setup time and easy operation.
VFD Stepless Speed Regulation
Equipped with frequency conversion speed control, the rotating speed can be adjusted smoothly to meet various welding process requirements.

Stable Load & Smooth Rotation
Designed with heavy-duty frame and high-strength PU rollers, ensuring 20-ton stable load, steady rotation and no slipping during welding.
Cost Saving & High Efficiency
Reduce manual alignment labor, improve welding consistency and overall production efficiency, ideal for mass cylindrical workpiece fabrication.
Products Description
√ Widely used for
girth welding of pressure vessels and boiler cylinders. It operates with automatic centering to reduce welding misalignment and ensure attractive weld formation.
√ Suitable for
the production of petrochemical pipelines and storage tank shells. It supports continuous rotary operation and greatly reduces labor costs for workpiece turning.
√ Ideal for
assembly and welding of wind power towers and large steel structural cylinders. The self-aligning design eliminates repeated center adjustment and saves time and labor.
√ Applicable to
processing of stainless steel tanks and anti-corrosion cylinders. PU rubber-coated rollers avoid scratching the workpiece surface and protect paint and base material.
√ Perfect for
rotary processes such as grinding, polishing and flaw detection of large cylindrical workpieces in heavy industry and mining equipment. Multi-function design ensures strong universal applicability.

Frequently Asked Questions
Please feel free to contact me at any time if there are any other details you would like to know.
What is the applicable workpiece diameter range for the 20-ton self-adjusting roller frame?
+
-
A: Applicable workpiece diameters Φ500mm–3500mm. The swing arm self-aligning structure automatically adapts to the cylinder diameter, eliminating the need for manual wheel gauge adjustment.
What material are the rollers made of, and will they scratch the workpiece surface?
+
-
A: Standard configuration includes steel-core polyurethane (PU) fully coated rollers, which are wear-resistant, non-slip, and have good toughness, preventing damage to the cylinder paint and metal surfaces.
Is the roller frame speed adjustable, and what is the speed adjustment method?
+
-
A: Supports variable frequency stepless speed regulation, with a linear speed adjustable from 0.1–10m/min. It operates smoothly with no impact during start-up and shutdown, meeting various welding processes.
What standard accessories are included with the shipment, and are installation accessories included?
+
-
A: The shipment includes a certificate of conformity, instruction manual, warranty card, anchor bolts, a complete set of vulnerable parts, and special installation tools. It is ready for immediate installation and use upon arrival.
How stable is the frame structure? Will it deform under heavy load?
