20Ton Self-Aligning Welding Turning Rolls for Vessel Welding

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
