en.Wedoany.com Reported - In June 2026, the smart manufacturing workshop of China's Lovol Heavy Industry Co., Ltd. in Qingdao, Shandong, continues to operate efficiently, with automated welding robots, AGV unmanned transport vehicles, and the MOM manufacturing execution system working in coordination. A medium-sized excavator rolls off the production line every 15 minutes. Lovol Heavy Industry has established a smart manufacturing system covering a full range of products, including excavators from 1.5 to 200 tons, loaders from 2 to 12 tons, mining wide-body dump trucks from 70 to 160 tons, and backhoe loaders. The welding automation rate reaches 90%, the painting automation rate reaches 95%, and the final assembly logistics automation rate reaches 80%.
Lovol Heavy Industry is a core enterprise in the construction machinery business segment under Weichai Power Co., Ltd. (000338.SZ/2338.HK). Its brand belongs to Weichai Lovol Intelligent Agricultural Technology Co., Ltd., with its headquarters located in Qingdao, Shandong. The company's business covers the R&D, manufacturing, and sales of construction machinery and agricultural equipment. Its products are sold to over 100 countries and regions worldwide. According to Weichai Power's 2025 annual report, the smart agriculture and construction machinery segment, to which Lovol Heavy Industry belongs, achieved annual operating revenue of approximately 17.31 billion yuan.
In the production and manufacturing process, Lovol Heavy Industry has established a smart manufacturing layout known as "two locations, three factories," connecting the entire chain from core component precision machining, structural part forming, and final assembly to factory commissioning. In the component production workshop, nearly 100 automated welding robots handle all core structural component welding processes, with the first-pass yield rate for key welds consistently exceeding 99%. The painting workshop uses a closed automated spray painting production line, employing environmentally friendly materials such as water-based paints and two-component epoxy solvent primers. The product paint finish can withstand various extreme global working conditions, including high temperatures, high humidity, and high salt spray. In terms of material flow, AGV unmanned transport vehicles and the intelligent warehousing system achieve seamless integration, automatically completing precise material distribution and flexible flow based on production tasks.
In terms of digital control, Lovol Heavy Industry relies on the MOM (Manufacturing Operations Management) production execution system to establish a quality traceability system covering the entire lifecycle of each piece of equipment. Each piece of equipment receives a unique identity identifier upon entry of its components into the factory. All processing, assembly, and inspection data are recorded in real-time by the system, forming a complete quality file. Each link in the production line is equipped with digital terminals, allowing operators to view work instructions and production tasks in real-time, while the system automatically verifies component models and assembly processes. In the event of a quality anomaly, the system immediately issues an alert and locks the problematic link, enabling staff to quickly trace back to specific component batches and processing records. The establishment of the smart manufacturing system has shortened the new product mass production cycle by approximately 30%, significantly reduced the production man-hours per unit of equipment, and enabled rapid response to customized order requirements for different regions and working conditions.
