3 Ton Heavy Duty Welding Positioner | Large Vessel & Heavy Steel Fabrication Turntable
Product Overview
3 ton heavy load welding positioner with 360° rotation and 0-135° electric tilting, frequency speed control, IP54 electrical protection, CE certified. Designed for thick tanks, pressure vessels and heavy structural steel welding.
This 3000kg heavy-duty welding positioner is specially upgraded to handle ultra-heavy workpieces, such as oversized pressure vessels, thick-wall storage tanks, large boiler barrels and extra heavy steel beams.
Welding uniformity is significantly enhanced, and the overall production efficiency of the fabrication workshop gets greatly improved.
The whole machine uses an integrally welded thick steel frame paired with a high-torque hardened gear reducer.
It runs smoothly stably under full rated load and large eccentric load, free from vibration and workpiece slipping issues.
Compatible with MIG, TIG, submerged arc welding machines and robotic welding systems.
Widely used in petrochemical equipment production, power boiler processing, heavy steel structure fabrication and offshore engineering sectors.

Circumferential and longitudinal seam welding for large-diameter pipes and heavy flanges
Welding forming of large box beams, H-beams and other heavy steel structural parts
Can run independently as single workstation or be integrated into full-automatic welding production lines
Operating Benefits & Efficiency Improvement
Eliminate repeated overhead crane hoisting and workpiece repositioning, cut labor input and avoid hoisting safety accidents
One-time clamping completes multi-angle positioning, labor cost reduced by more than 45% compared with traditional operation mode
Ideal for mass continuous production, effectively lifting the overall output capacity of heavy steel fabrication workshops
Packaging & Shipping
Complete machine fixed with high-strength steel wire and packed in export-standard solid wooden cases to avoid collision and deformation during long-distance sea and land transportation.
Precision electrical control box and motor components wrapped with thick waterproof plastic film to prevent moisture and ocean salt spray corrosion.
Supports multiple international trade terms: EXW, FOB, CIF, CFR.
Arrange loading and delivery schedule flexibly according to customer-designated port or inland warehouse address.
Frequently Asked Questions
Q1: What is the maximum eccentric load the 3 ton welding positioner can support?
A1: The maximum allowable eccentric distance reaches 220mm. It still operates stably without jitter even when installing asymmetric oversized vessel workpieces.
Q2: Can rotation speed and tilting angle be locked during automatic circular seam welding?
A2: Yes. Rotation speed can be fixed steadily for continuous girth welding; any tilting angle can be mechanically locked to prevent position deviation during long-time welding.
Q3: Can the worktable match standard chucks and custom tooling fixtures?
A3: The surface is equipped with standard T-slots with high bearing capacity. Three-jaw chucks and customer self-designed fixtures can be directly installed and fastened.
Q4: Is linkage access available for welding robots and manipulators?
A4: External signal interfaces are reserved on the control cabinet, supporting synchronous linkage with welding manipulators and robot systems to form integrated automatic welding cells.
Q5: Can the input voltage be customized for different national power grids?
A5: Standard configuration is 380V/50Hz. Custom voltage and frequency such as 220V, 415V can be adjusted to fit local power supply standards in different countries.
