Synchronized Chain Hydraulic Jacking System 12-120t Capacity

Key Features:

1. Absolute Synchronization: The hallmark feature. The PLC constantly compares jack positions and adjusts hydraulic flow in real-time, guaranteeing all lifting points move together within strict tolerances (±2-5mm), preventing dangerous tank shell distortion.

2. Real-Time Monitoring & Control: Operators have complete visibility of loads and positions at every jack via the HMI, enabling proactive intervention and ensuring process transparency.

3. Robust Chain Technology: Alloy steel lifting chains offer superior tensile strength, abrasion resistance, and tolerance to harsh site conditions (dust, moisture) compared to wire ropes. They are also easier to inspect for wear.

4. Inherent Safety: Multiple layers of safety: structural (chain strength), mechanical (locking nuts), hydraulic (pressure relief), and electronic (PLC monitoring/alarms). The positive grip of the chain is highly secure.

5. High Power Density: Delivers enormous lifting forces from compact jacks, minimizing the required workspace around the tank perimeter.

6. Smooth & Controlled Motion: Hydraulic actuation ensures jerk-free lifting and lowering, vital for the structural integrity of the tank shell during the operation.

7. Ease of Setup & Operation: Modular components simplify rigging. The intuitive HMI interface makes complex lifting operations manageable by trained personnel.

8. Durability: Designed for heavy industrial use and repeated deployment on demanding construction and maintenance projects.

Applications:

• Critical Annular Plate Welding: The primary application. Lifting the tank shell to create the necessary access gap for welding and inspecting the crucial joint between the tank floor and the shell wall, ensuring leak-proof integrity (per API 650 standards).

• Comprehensive Base Inspection & Repair: Elevating the tank provides full access to the tank bottom, foundation ringwall, and underside of the shell for Non-Destructive Testing (NDT), corrosion assessment, concrete repair, or bottom plate replacement.

• Tank Foundation Modifications/Replacement: Enabling the removal and reconstruction of the concrete foundation or installation of new seismic base isolation systems while the tank is safely elevated.

• Controlled Tank Setting: Precise final lowering and positioning of the tank onto prepared foundations, piles, or specialized supports.

• Tank Raising for Roof Access/Work: Facilitating the installation, maintenance, or replacement of fixed or floating roofs.

• Emergency Stabilization & Recovery: Used in situations where a tank has settled unevenly or requires stabilization for remediation work.

• Industry Sectors: Essential for EPC contractors and owners in Crude Oil Storage, Refined Product Storage (Gasoline, Diesel), Chemical Storage (Acids, Solvents), LNG/LPG Storage (outer containment tanks), Large Potable Water & Wastewater Tanks, and Bulk Storage Silos.
