When welding extremely long, awkward, or heavy structural assemblies—such as trailer frames, large-diameter pipes, or long structural beams—a standard single-base positioner cannot safely support the overhanging weight.
The HBA Series Double Column Welding Positioner provides the ultimate solution. Operating on a head-and-tail stock principle, it supports your massive workpiece from both ends. This allows welders to easily rotate long assemblies a full 360 degrees, ensuring every seam is welded in the optimal flat or horizontal position without relying on risky crane maneuvers.
Because no two fabrication shops are exactly alike, the HBA series can be highly customized to fit your specific production line:
If you weld parts of varying lengths, you can order the tail base mounted on a rail system.

Note: Dimensions listed are for a single column unit. The overall length of your system will depend on your specific installation and rail distance.
A1: Yes. The system is designed to rotate long workpieces symmetrically. Torsional stress on your workpiece is avoided by ensuring smooth, synchronized rotation between the driving head and the supporting tail plate.
A2: When rotating a 40-ton structural frame, a sudden stop creates massive kinetic energy that can damage the machine's gears or snap the workpiece fixtures. Our system automatically ramps the speed down before stopping, absorbing that impact smoothly.
A3: Because of the massive loads and the necessity for the head and tail stocks to be perfectly aligned, this specific double-column equipment requires proper civil foundation engineering before installation. We will provide the foundation blueprints once your order is confirmed.
