This machine is a special equipment for U-shaped and box-shaped assembly of box girders, consisting of a host machine, a conveying roller table, a centering device, a positioning device, a hydraulic system, and an electric control system. This machine uses the method of moving the workpiece without moving the host machine to clamp the workpiece in sections, and manually spot weld the clamped workpiece to form it.
The characteristics of this machine are: U-shaped assembly and box shaped assembly are completed on one device, reducing costs and saving layout space.
