The 3-axis gantry crane picks up a specialized rotating tool, placing steel plates on all four sides into a square tube jig for assembly. Once assembled, the gantry crane transfers the square tube to the root-welding station for root and fill welding. After welding one side, the gantry crane uses a rotating spreader to flip the tube 180 degrees to proceed with welding on the other side.
This production line's core strengths are advanced processes (e.g., submerged arc welding) for boosted welding efficiency/quality, full automation to minimize manual work, and high-efficiency mass production with precision.

The square tube production line adopts intelligent assembly line operation. After the RGV transports the cut parts to the welding area, the three-axis gantry crane collaborates with the assembling machine to achieve precise positioning of the box column. Subsequently, the box girder gantry equipment performs back-grouting and filling welding, and an electric square tube rotating hoist is used to complete the welding.
The core advantages of this production line lie in: the use of advanced processes such as submerged arc welding to significantly enhance welding efficiency and quality, along with fully automated operation throughout the process, reducing manual intervention. The entire system ensures product precision while achieving mass and efficient production.

The intelligent production line for steel joints utilizes full-process automation, encompassing smart cutting & sorting, deburring, as well as component assembly, welding, and finishing. By leveraging the collaborative operation of intelligent equipment such as 3-axis gantry robots and RGVs, it achieves efficient and precise production. Its benefits include increased capacity, consistent product quality, and significantly improved operational safety through the application of smart manufacturing technologies, thereby revolutionizing traditional steel structure production processes.

Production Line Overview: The finished steel structure component line adopts intelligent full-process operations, utilizing 3-axis gantry cranes, dual-axis rotary positioners, welding robots, and other smart equipment to achieve precise assembly and welding. After laser inspection ensures component accuracy, grinding robots automate weld finishing, followed by end-face milling and shot blasting to enhance quality. Finally, fully enclosed coating stations complete painting and drying.

Key Advantages:
Integrated advanced technologies (laser inspection, smart grinding, intelligent logistics) ensure product precision.
Full automation boosts production efficiency.
Closed-loop spraying systems enable eco-friendly operations.
Smart control systems ensure full quality traceability, significantly upgrading manufacturing quality and delivery speed for steel components.

The HHBT UTS slab production line is equipped with a range of automated equipment. It can automatically process the size and shape of slab reinforcement based on CAD drawings, then hoist and place them onto the slab mold table. After that, concrete is automatically distributed and vibrated by the concrete distribution workstation, and the slab enters the curing chamber before being taken out.

HHBT hollow slab production: Steel pipe molds are pre-positioned in the mold table via pipe-inserting equipment, followed by concrete placing and curing before pipe extraction. Automated processes for thickness calibration, cross-cutting, and hole punching enable fully automated, industrialized assembly-line production of HHBT hollow slabs.
