Covered wagon roof assembly jig 

This jig is designed for assembling and semi-automatically welding the exterior seams of a covered wagon roof. It provides precise positioning and secure clamping of framing straps, arches, transoms, and sheet panels ahead of welding — ensuring consistent roof geometry and a shorter assembly cycle time.

Operating sequence

  1. Load and position the roof framing straps lengthwise against the stop.
  2. Engage the pneumatic clamps to secure the straps in the transverse direction.
  3. Install and clamp the transoms.
  4. Load the sheet panels, edge trims, and arches onto the centering guides and stops.
  5. Run the traveling beam in to clamp and tack-weld the sheets to the transoms, arches, and framing straps.
  6. Return the beam to its home position and complete the final roof welding.
  7. Transfer the finished roof to storage.

Key advantages

  • Pneumatic clamping keeps roof geometry consistent throughout assembly.
  • Frequency-controlled beam drive delivers smooth travel without jerking or binding.
  • Copper backing plates in the weld zone prevent the workpiece from fusing to the tooling.
  • Knock-down, transportable construction — assembled and installed on the customer’s site.
