Product Description
40 Ton Self-Aligning Welding Rotator Wind Power Tower Section Girth Welding Machine
Product Overview
This 40-ton self-aligning welding rotator is specially optimized for on-shore wind tower segment manufacturing. With automatic centering swing-arm structure, it adapts to varying wind tower diameters without manual wheel-base adjustment. High-load PU rollers, VFD stepless speed regulation and heavy-duty welded frame guarantee stable continuous circumferential welding for wind power cylinder sections, reduce workpiece slippage and surface scratch, widely matched with SAW/MIG welding processes for wind tower mass production.

Frequently Asked Questions
Q1: Is this rotator specially for wind tower production?
A: Yes, this 40-ton self-aligning rotator is optimized for wind-tower segment girth welding, also works for pressure vessels and large steel cylinders.
Q2: Do I need manually adjust roller distance when changing different wind tower diameters?
A: No. Self-aligning swing-arm structure automatically adapts diameter changes, no manual wheel-base adjustment required.
Q3: Can PU rollers avoid scratching wind tower painted surface?
A: High-density PU roller effectively prevents scratch, suitable for finished or semi-finished wind tower shell welding.
Q4: Can you change voltage to match our local 3-phase power supply?
A: Yes, we redesign whole electrical system for 380V/415V/480V 50/60Hz according to customer site requirement.
Q5: Can this rotator link with welding manipulator?
A: It can reserve linkage signal interface as optional upgrade.
Q6: What documents can you provide for import customs clearance?
A: We can offer commercial invoice, packing list, CE documents, factory test report and English technical drawings.
Q7: What is your delivery lead-time for 40-ton wind-power rotator?
A: Normally 30-35 working days upon receiving advance payment.
Please share your wind-tower workpiece diameter, weight and local power condition, we will send complete datasheet and competitive factory offer for your reference.
