Independently developed by Shandong Zhongji Luyuan Machinery, the LYGH-2200 Reinforcement Cage Rolling Welding Machine is an intelligent CNC processing equipment specially designed for large-scale infrastructure projects such as bridges, tunnels, expressways, nuclear power and hydropower projects. With core advantages of "high precision, high efficiency, low energy consumption and easy operation", this machine completely solves the pain points of traditional reinforcement cage processing, such as "large error, high labor consumption and low efficiency", and has become a preferred equipment in the steel bar processing link of the current infrastructure industry.

I. Core Advantages: Breakthroughs in Three Dimensions to Reshape Processing Standards
1. Micron-level Precision Control to Meet High-end Engineering Requirements
The LYGH-2200 Reinforcement Cage Rolling Welding Machine is equipped with a full servo motor drive system, combined with a Type 150 worm gear reducer and a chain-driven structure. It achieves precise control with an error of only 1mm when moving 100 meters, and the welding precision stably reaches ±0.5mm level. Innovatively, the equipment adopts 40×60mm cold-drawn steel cross 筋 (cross bars) positioning and a Type 80 hydraulic support structure. A single unit can bear a weight of 50 tons and is suitable for processing full-specification steel bars of 8-32mm. Whether it is large-diameter bridge reinforcement cages or high-precision nuclear power steel skeletons, it can perfectly meet the construction specifications.
2. 4-fold Efficiency Improvement to Significantly Reduce Labor Costs
Compared with traditional manual welding (processing 2-3 standard cages per day), the LYGH-2200 CNC Reinforcement Cage Rolling Welding Machine realizes automated continuous processing. It can complete the processing task of 15 standard cages (2m in diameter, 12m in length) per day, with an efficiency improvement of more than 4 times. At the same time, the equipment only requires 2-3 operators, reducing labor input by 80% compared with manual processing, which effectively alleviates the problems of "difficulty in hiring workers and high labor costs" in infrastructure projects. For example, in the reconstruction and expansion project of Shenhai Expressway, this equipment completed the processing of 21,000 tons of steel bars in a single month, with a 100% acceptance qualification rate.
3. Dual Upgrades in Intelligence and Energy Conservation, in Line with Green Infrastructure Concepts
The LYGH-2200 Reinforcement Cage Rolling Welding Machine integrates a 5G remote monitoring module, supporting real-time optimization of welding parameters, remote viewing of equipment status and fault early warning. This reduces the equipment failure rate to below 1% and shortens the shutdown maintenance time. In addition, the equipment is equipped with an energy-saving motor system, whose daily power consumption is 40% lower than that of traditional rolling welding machines, saving more than 30,000 yuan in electricity fees annually. It fully conforms to the national "dual carbon" policy and the development needs of green infrastructure.
II. Core Configuration: Modular Design to Adapt to Multi-scenario Needs
III. Application Scenarios: Covering All Types of Infrastructure Projects
With high adaptability, the Shandong Zhongji Luyuan LYGH-2200 Reinforcement Cage Rolling Welding Machine is widely used in:
At present, this machine has been used in batches in projects of central enterprises such as China Construction Third Engineering Bureau, China Railway and China Communications Construction, including Wenmeng Railway and Guangzhou Expressway Reconstruction and Expansion Project, all achieving project results of "zero-fault operation + 100% acceptance qualification".
