Project Overview & Engineering Challenges

The Jintang New Materials Project features China's first sea-crossing pipe gallery, a critical infrastructure milestone for the Yangtze River Delta's petrochemical industry. The project involved installing 31 oversized pipe gallery modules, with a maximum single weight of 515 tons and lengths reaching 43 meters. Because of the soft mudflat geology and low soil bearing capacity, traditional marine lifting and temporary bridge installations were ruled out due to extreme costs and schedule delays.

The Solution: High-Altitude Jacking & Sliding

Technical team fine-tuning the KIET intelligent hydraulic heavy-duty sliding trolley system before the jacking process.

The construction contractor engineered an innovative "Transport + Lifting + High-Altitude Bridge Deck Jacking & Sliding" integrated method to bypass the geological constraints and eliminate traditional piece-by-piece field assembly.

KIET Equipment Capability & Scope Boundary

 Real-time monitoring and control of the synchronized hydraulic system via the central PLC unit.

Notice on Scope of Service: KIET specializes exclusively in matching and supplying high-performance heavy-duty equipment tailored to the client’s predefined engineering specifications. KIET does not undertake the engineering design or liability of the construction plan itself.

To execute the client's specialized high-altitude sliding plan, KIET supplied a synchronized system of 16 Intelligent Hydraulic Heavy-Duty Sliding Trolleys. Controlled by a central PLC system, these trollies feature dual jacking and sliding functionalities, automated load-linkage, and real-time deviation correction to handle extreme tonnage safely.

Project ROI & Performance Metrics

• 3-Month Schedule Reduction: Utilizing this method instead of traditional onsite assembly shortened the project timeline by at least three months, securing early commissioning for the owner.
• Massive Efficiency Gains: Traditional winches or push-sliding methods typically require up to 2 days to position a single module. The KIET-equipped synchronized system achieved a precise sliding speed of 3meters per minute, drastically accelerating throughput.
• Precision Control: The PLC-controlled hydraulic system maintained exact path alignment and millimeter-level positioning accuracy, successfully navigating complex marine environments.
