Long Axis Welding Turning Rolls For 12m Workpiece | Multi‑support Roller Welding Rotator

This long‑shaft welding turning rolls is specially developed for extra‑long cylindrical workpieces up to 12 meters. Adopting multi‑group supporting roller layout, it effectively solves workpiece sagging and deformation during rotation. Equipped with VFD stepless speed regulation, it keeps uniform rotary motion for long‑pipe, long‑cylinder girth welding. Widely used in long pipeline, tower barrel, large‑length metal cylinder manufacturing.

• Multi‑support roller layout, specially designed for 12‑meter extra‑long cylindrical workpieces, reduces workpiece bending‑sagging risk
• VFD stepless speed control, stable rotating performance for consistent circumferential welding seam quality
• High‑strength polyurethane rollers, great friction performance, prevent slipping and protect workpiece outer surface
• Integral heavy‑duty frame with stress‑relief annealing treatment, strong rigidity for long‑time heavy‑load operation
• Hand‑held pendant controller, convenient on‑site start‑stop and real‑time speed adjustment
• Flexible expandable structure, extra roller groups can be added for longer workpieces; supports multiple optional upgrades

• Complete multi‑group driving‑idler roller units for 12m workpiece
• High‑load polyurethane rollers
• VFD frequency conversion control cabinet
• Hand‑held pendant operation box
• Cycloidal pinwheel reducers and matched driving motors
• Complete power cables and connecting harness
• Stress‑relief welded heavy‑duty base frame

• Solid steel rollers for high‑temperature, heavy‑abrasion welding environment
• Wireless remote‑control operating kit
• Overload safety protection module
• Additional auxiliary roller groups for ultra‑long workpieces
• Synchronous linkage assembly for welding manipulator
• Custom voltage & frequency for different‑country power grid

This long‑shaft welding rotator is aimed at girth welding of over‑length cylindrical components:

• 12‑meter long steel pipe and pipeline section welding
• Tower barrel and wind‑power related cylinder fabrication
• Elongated pressure‑vessel and heat‑exchanger shell processing
• Long metal cylinder circumferential seam welding
• Production workshop for extra‑length cylindrical structural parts

Full‑function inspection for each set. Qualified products are cleaned and packed by export‑standard fumigated wooden cases before shipment.
