The 20Ton Self-Aligning Welding Rotator HGZ20 is a heavy-duty automatic welding roller frame specially manufactured for cylindrical workpieces. This self-centering turning roll is widely applied in pressure vessel, boiler, steel tank, pipe and cylinder welding industries. Different from conventional adjustable roller frames, this self-aligning welding rotator can automatically center and adapt to various cylinder diameters without manual spacing adjustment, greatly improving welding accuracy and production efficiency.

• Automatic self-aligning and self-centering function, no manual calibration required
• Heavy duty 20-ton load capacity for large cylinder and pressure vessel welding
• Dual-motor synchronous drive system for stable and uniform rotation
• VFD stepless speed adjustment to match all automatic welding processes
• Wear-resistant and customizable rollers to protect workpiece surface
• Thickened welded structure with stress relief treatment, durable and deformation-free
• Complete safety protection system for industrial continuous production

Adopt thick Q235 steel plate & profile steel integral welding, finished with stress relief annealing to avoid deformation under long heavy load.

Cast steel + forged piece machining, high mechanical strength for automatic self-aligning swing action.
