Recently, the LYGH-800 Rebar Cage Rolling Machine, specially developed to address pain points such as low efficiency and poor precision in rebar cage processing in the infrastructure field, has been officially launched on the market. Jointly developed by Shandong Zhongji Luyuan Machinery and a university research team after two years of intensive research, this equipment has redefined the standards for rebar cage processing with a number of innovative technologies, injecting new impetus into the high-quality development of China's infrastructure industry.

In traditional infrastructure construction, rebar cage processing has always been a key link restricting project progress. In the past, rebar cages mostly relied on manual binding or processing with simple equipment, which not only required a large number of laborers but also resulted in low processing efficiency. Taking a rebar cage with a diameter of 2 meters and a length of 12 meters as an example, the traditional processing method required 8-10 workers to work continuously for 12 hours to complete one set. Moreover, affected by manual operations, the error in the spacing of the steel bars in the rebar cage often exceeded 5 millimeters, and the welding quality was unstable. Problems such as poor bonding during subsequent concrete pouring were prone to occur, posing hidden risks to the structural safety of the project. At the same time, during manual processing, workers had to bend over for a long time and carry heavy steel bars, resulting in high labor intensity and a relatively high risk of safety accidents. As China's infrastructure projects move towards larger-scale and more refined development, the traditional rebar cage processing method can no longer meet the project's requirements for efficiency, precision, and safety.

The emergence of the LYGH-800 Rebar Cage Rolling Machine has completely changed this situation. This equipment has achieved multiple breakthroughs in technology. Firstly, in terms of processing efficiency, it adopts a "dual-spindle synchronous drive + automatic feeding" design and is equipped with a high-precision servo motor, enabling integrated operations of automatic steel bar feeding, automatic positioning, automatic welding, and automatic cutting. Practical tests show that for a standard rebar cage with a diameter of 2 meters and a length of 12 meters, the LYGH-800 only requires 3 operators (1 main operator and 2 auxiliary feeding workers) to complete the processing of one set in 4 hours. Based on an 8-hour working day, it can process 4-5 sets per day, which is 6-8 times more efficient than traditional manual processing. This significantly reduces labor input and shortens the construction cycle.

Precision control is another major highlight of the LYGH-800. The equipment is equipped with an industrial-grade numerical control system. Through digital programming, parameters such as steel bar spacing and welding point positions can be accurately set, with a positioning accuracy of ±1 millimeter, far exceeding the ±5-millimeter error standard of traditional manual processing. At the same time, the high-definition camera and laser positioning device equipped with the equipment can monitor the welding process in real time and automatically adjust the welding current and welding speed, ensuring that the penetration depth and fillet height of each welding point meet national standards, and the welding qualification rate remains stable above 99.5%. The person in charge of a highway project stated that the rebar cages processed by the LYGH-800 have an extremely high degree of fit with the pile holes during on-site installation, requiring no secondary adjustments. This alone saves the project nearly 20% of the installation time.

The LYGH-800 also performs outstandingly in terms of intelligence and safety. The equipment is equipped with an Internet of Things (IoT) module, enabling remote monitoring, fault diagnosis, and data traceability functions. Managers can check real-time data such as equipment operation status, processing progress, and consumables usage through a mobile APP or computer backend. In case of any abnormality in the equipment, the system will automatically issue an alarm and push the cause of the fault and solutions, reducing equipment downtime. In addition, the equipment is equipped with multiple safety protection devices, including emergency stop buttons, infrared safety light curtains, and guardrails. When operators approach dangerous areas, the equipment will automatically stop, effectively preventing the occurrence of mechanical injury accidents.

It is worth mentioning that the LYGH-800 has strong adaptability. It can process various types of rebar cages with a diameter of 230 millimeters to 800 millimeters and a length of 3 meters to 24 meters, meeting the needs of different infrastructure scenarios such as bridge pile foundations, subway tunnels, and high-rise building foundations. At the same time, the equipment adopts a modular design, with strong universality of components, convenient later maintenance, and maintenance costs reduced by approximately 30% compared with similar equipment.

At present, the LYGH-800 Rebar Cage Rolling Machine has been put into use in a number of key infrastructure projects. In a cross-river bridge project, this equipment processes an average of 8 sets of rebar cages per day, saving 60% of labor costs compared with traditional processing methods and shortening the rebar cage processing cycle of the project by 40 days. Moreover, the rebar cages processed have passed third-party testing, and all indicators are better than the design standards. The chief engineer of the project sighed, "The LYGH-800 from Zhongji Luyuan Machinery not only solves our problem of tight construction schedules but also provides a solid guarantee for the quality of our project."

Industry experts point out that the launch of the LYGH-800 Rebar Cage Rolling Machine marks the transition of China's rebar cage processing equipment from "semi-automatic" to "fully automatic, high-precision, and intelligent". It not only improves the construction efficiency and quality of individual projects but also promotes the technological upgrading and industrial transformation of the entire infrastructure industry. With the in-depth advancement of China's strategies such as "Transportation Powerhouse" and "New Infrastructure", such efficient and intelligent construction machinery will have a broader application space.

According to engineers from Zhongji Luyuan Machinery, in the next step, they will continuously optimize the performance of the LYGH-800 based on market feedback. They plan to add an AI visual inspection function to further improve the equipment's automation level and quality control capabilities. At the same time, they will develop customized versions adapted to more special scenarios, providing more comprehensive solutions for the infrastructure industry and helping China's infrastructure cause enter a new stage of higher-quality development.
