Introduction:
As a leading manufacturer of advanced hydraulic lifting equipment, Jiangsu Canete is dedicated to providing high-precision, efficient, and reliable solutions for the demanding needs of bridge construction and maintenance projects. Our innovative technologies are engineered to meet the critical challenges faced by project contractors worldwide. This case study highlights the successful application of Jiangsu Canete's hydraulic systems in the recent Shenlu Expressway 4800-ton bridge project, demonstrating our commitment to engineering excellence and supporting crucial infrastructure maintenance.
The Challenge: Lifting a 4800-Ton Bridge for Bearing Replacement on the Shenlu Expressway
The Shenlu Expressway project required the lifting of a massive 4800-ton continuous box girder ramp bridge to facilitate the replacement of its bearings. This complex undertaking needed to be executed without interrupting vital traffic flow. The significant span and dispersed load-bearing points of the bridge presented a considerable challenge, as uneven or uncontrolled lifting could lead to structural cracking, a risk that demanded a precise and reliable lifting solution.
Jiangsu Canete's Solution: High-Precision Hydraulic Lifting System
To address these critical requirements, the project utilized a comprehensive lifting system manufactured by Jiangsu Canete, comprising:
24 Units of Outer Ring Nut Self-Locking Hydraulic Jacks: These robust jacks, each with a capacity of 300 tons, formed a carefully engineered lifting matrix. This configuration ensured that the total lifting capacity significantly exceeded the 4800-ton weight of the bridge, providing a substantial margin of safety. The mechanical self-locking feature of these jacks offers enhanced safety and stability during the lifting operation.
PLC Intelligent Synchronous Lifting Hydraulic System: This state-of-the-art system is a core product of Jiangsu Canete, designed for precise and coordinated control of multiple lifting points. The system's capabilities were crucial in this project:
Real-time Synchronization Control: The PLC system continuously monitors and adjusts the performance of all 24 hydraulic jacks, maintaining a remarkable synchronous lifting accuracy of ≤0.5mm across all points. This precision is essential to prevent stress on the bridge structure during lifting.
Dynamic Feedback of Support Reaction Force: The intelligent system incorporates sensors that provide real-time feedback on the load distribution at each lifting point. This data allows the system to automatically fine-tune the output force of individual jacks, ensuring a perfectly balanced and "zero-damage" lift of the bridge.
Meeting Contractor Demands: Precision, Efficiency, and Reliability
The successful completion of the Shenlu Expressway bridge lifting project underscores how Jiangsu Canete's hydraulic solutions directly address the key demands of bridge construction and maintenance contractors:
High Precision: The millimeter-level accuracy achieved by our PLC intelligent synchronous lifting system demonstrates our commitment to providing equipment capable of the most demanding tasks, minimizing risk and ensuring structural integrity.
High Efficiency: The controlled and synchronized nature of the lifting operation, managed by our intelligent system, streamlines the bearing replacement process, potentially reducing project timelines and associated costs.
Safety and Reliability: The combination of robust self-locking hydraulic jacks and the intelligent control system provides a safe and reliable lifting solution, mitigating the risks associated with heavy lifting operations on critical infrastructure.
Conclusion:
The successful 4800-ton bridge lifting on the Shenlu Expressway serves as a powerful demonstration of the capabilities and reliability of Jiangsu Canete's hydraulic lifting technology. As a dedicated manufacturer, we are committed to providing project contractors with the high-precision, high-efficiency, and safe hydraulic solutions they need to tackle complex bridge construction and maintenance challenges.
