Product Description
20Ton Self-Aligning Welding Turning Rolls for Vessel Welding
Product Overview
The 20-ton self-aligning welding rotator is medium-heavy load welding auxiliary equipment designed for large cylindrical workpieces. Featuring dual-motor synchronous drive and self-adjusting roller structure, it automatically centers tanks and pipes without manual distance adjustment. With VFD speed control, it provides stable uniform rotation for high-quality circumferential welds. Widely used in pressure vessels, storage tanks, boilers, thick steel pipes, and petrochemical equipment manufacturing.
Key Performance Features
- Dual-motor synchronous drive provides strong traction and stable running under full 20-ton load, eliminating slipping during long-hour welding operations
- Self-aligning roller mechanism automatically adjusts angle to center cylindrical workpieces, significantly reducing setup time
- VFD stepless speed regulation enables smooth low-speed rotation without vibration, ideal for submerged arc automatic welding
- Optional PU rollers to protect stainless steel surfaces; forged steel rollers available for heavy carbon steel workpieces
- Thickened integral welded frame provides high rigidity and anti-deformation characteristics, suitable for heavy-duty continuous production
- Easy integration with welding manipulators to build automatic cylinder girth welding production lines
