Introduction to the Equipment
A Chuck Type Tank Hydraulic Jacking System is an engineered,
synchronized lifting solution designed specifically for the
vertical elevation of large-scale storage tanks, vessels, and other
heavy structures during their construction, maintenance, or
relocation. Unlike generic jacks, this system employs a specialized
"chuck" mechanism that grips a temporary steel column (or a
permanent tank leg), allowing for controlled, incremental, and
highly stable lifting. The system operates on the principle of
climbing jacking, where the jack unit ascends the column by
alternately gripping and releasing, making it ideal for lifting
massive loads to significant heights over extended periods.

System Components & Key Parameters
A complete system typically consists of the following key
components:
Jack Units (Hydraulic Cylinders): The core lifting elements. Each unit integrates a hydraulic cylinder and a self-locking chuck mechanism.
Lifting Capacity per Unit: Ranges from 50 Metric Tons to 500 Metric Tons.
Standard Stroke per Cycle: Typically 150 mm to 300 mm.
Working Pressure: Usually 63 MPa to 70 MPa.
Hydraulic Power Unit (HPU): The system's heart, comprising an electric motor, hydraulic pump, reservoirs, valves, and filters.
Power: 5.5 kW to 22 kW, depending on the number of jacks.
Flow Rate: Adjustable, e.g., 2.5 L/min to 10 L/min.
Synchronous Control System: The "brain" of the operation. It uses PLCs and sensors to monitor and control each jack's position in real-time.
Control Accuracy: Typically ±1.0 mm.
Display: Touchscreen HMI for real-time monitoring of load, pressure, and stroke.
Temporary Steel Columns: High-strength steel columns that provide the guided path for the jacks to climb.

Salient Features
High Load Capacity: Capable of lifting loads exceeding 10,000 tons by using multiple jacks in unison.
Ultra-Precise Synchronization: The computerized control system ensures all jacks move in perfect harmony, preventing any structural twisting or bending.
Safety & Reliability: Features mechanical self-locking chucks that hold the load indefinitely, even in the event of a power or hydraulic failure. Overload protection is standard.
Modular & Scalable: The number of jack units can be configured based on the project's weight and geometry requirements.
Efficiency: Allows for continuous, controlled lifting, drastically reducing construction time compared to traditional methods like crane-assisted lifting.

Primary Applications
This system is indispensable in industries involving large metal
structures:
Tank Construction: Lifting the roof and upper courses of large floating roof tanks (e.g., oil storage tanks) from the ground level, enabling a "jack-and-slip" construction method.
Tank Maintenance: Elevating entire storage tanks for inspection, repair, or replacement of foundation and bottom plates without emptying the product.
Heavy Structure Installation: Used in power plants, chemical plants, and shipyards for installing large reactors, modules, and ship sections.
Bridge Lifting: For synchronously lifting bridge decks and segments during construction or retrofit projects.
