Zhongji Luyuan Machinery Completes Moldova Infrastructure Reinforcement Cage Installation with Intelligent CNC Equipment

2025/12/23 15:10

Shandong Zhongji Luyuan Machinery Co., Ltd. (Zhongji Luyuan Machinery) has achieved a major milestone by successfully finishing the reinforcement cage installation for a key infrastructure project in Moldova, leveraging its self-developed intelligent numerical control (CNC) equipment. This achievement not only injects advanced Chinese technological strength into the upgrading of Moldova's regional transportation network but also represents a pivotal practice of China's intelligent infrastructure equipment in the Eastern European market, ushering in a new phase of Sino-Moldovan cooperation in the infrastructure sector.

As a critical project for Moldova to enhance regional connectivity, the initiative involves large-scale pile foundation construction that imposes rigorous demands on the processing precision and installation quality of reinforcement cages. To meet these high standards, Zhongji Luyuan Machinery deployed a dedicated professional technical team and adopted core intelligent equipment, including the SGH22-12 CNC reinforcement cage rolling machine and automatic welding workstation. Notably, the automatic welding workstation integrates full-chain functions such as steel straightening, feeding, positioning, welding, cutting, and collection to realize an unmanned operation process, covering the entire lifecycle from reinforcement cage fabrication to on-site installation with intelligent automation.

During the construction phase, Zhongji Luyuan's intelligent equipment showcased outstanding technical superiority, fully demonstrating the advantages of Chinese intelligent manufacturing: Equipped with a sophisticated PLC + servo motor control system, the SGH22-12 CNC rolling machine achieved precise control of reinforcement cage diameter error within ±5mm and stirrup spacing accuracy within ±10mm, fully complying with the strict EN 10080 European standard for construction steel products. The integrated automatic workflow, from feeding to welding, significantly reduced labor dependency—while traditional manual processing of a 12m reinforcement cage requires over 10 workers and yields only 1-2 sections per 8-hour shift, Zhongji Luyuan's automatic welding workstation needs merely 3-5 auxiliary operators. This intelligent solution boosts single-shift output by over 50%, with the SGH22-12 model capable of completing a 12m standard section in 2 hours, shortening the construction period by more than 35%.

Addressing the space constraints at the Moldovan construction site, Zhongji Luyuan's technical team implemented optimized equipment layout planning. The team strictly adhered to local safety regulations, including maintaining a lifting height of 5.5 meters and an equipment spacing of 1.5 meters, ensuring a smooth and accurate hoisting process free from equipment collisions or safety incidents. A notable technical highlight is the adoption of carbon dioxide gas shielded welding process for the reinforcement cages, which ensures robust bonding between main reinforcement bars and stirrups. This welding method not only enhances weld strength but also provides excellent corrosion resistance, effectively guaranteeing the long-term structural stability of the pile foundations. Additionally, the sound measurement tubes embedded as per design requirements were precisely positioned, laying a solid foundation for subsequent project quality inspection and acceptance.

The supervision party of the Moldovan project commended Zhongji Luyuan Machinery, stating that the company's construction technology and equipment level meet internationally advanced standards. Its efficient contract fulfillment has played a crucial role in ensuring the project progresses as scheduled. As a leading enterprise in China's intelligent steel processing equipment industry, Zhongji Luyuan Machinery has profound expertise accumulated over years of dedication to the sector. Its products have been widely applied in major domestic infrastructure projects such as high-speed railways, expressways, and large bridges, supporting renowned enterprises including China Railway No.5 Engineering Bureau and China Construction Third Engineering Bureau in completing numerous benchmark projects. Similar to its successful application in the Liansu Expressway project—where the equipment achieved a cumulative cost saving of 120,000 yuan and halved personnel input—the Moldova project further validates the company's technological advantages.

The successful entry into the Moldovan market is a strategic move by Zhongji Luyuan Machinery to respond to the Belt and Road Initiative and expand its global footprint into Europe. As Moldova accelerates its integration into the European infrastructure network, Zhongji Luyuan's intelligent equipment is expected to drive technological upgrading in the region's construction industry and unlock new opportunities for Sino-Moldovan cooperation in high-end manufacturing. Moving forward, Zhongji Luyuan Machinery will continue to deepen its presence in overseas markets, leverage its technological innovation capabilities to provide customized Chinese solutions for infrastructure construction in more countries, and contribute to advancing global connectivity and sustainable development.
