The Efficient Intelligent Steel Bar Truss Welding Production Line is core equipment independently developed by Shandong Time Machinery Technology Co., Ltd. for the prefabricated construction and steel structure building sectors. Integrating a self-developed operating system, high-precision control, and efficient welding technology, it realizes full-process automated production of steel bar trusses from raw material feeding, forming, welding to finished product collection. It significantly improves production efficiency, ensures stable welding quality, and reduces labor and time costs.

 

Core Product Advantages

1. Full-process Automation: From feeding, straightening, forming, welding to counting and collection, no manual intervention is required, reducing operational errors and improving production continuity.

2. High-quality Core Components: The Truss Girder Welding Machinery utilizes components from renowned brands-such as CHINT low-voltage control elements, MEAN WELL switching power supplies, AIRTAC pneumatic components, and HIWIN linear guides-to ensure long-term stable operation and reduce maintenance costs.

3.Truss girder welding machinery is capable of producing steel rebar trusses in a wide range of specifications and heights, meeting the material supply needs of diverse construction projects, including prefabricated buildings, industrial facilities, and civil structures.

4. Wide Adaptability: Can produce steel bar trusses of various specifications and heights, meeting the raw material supply needs of different engineering scenarios such as prefabricated construction, industrial factories, and civil buildings.
