Synchronized Chain Hydraulic Jacking System 12-120t Capacity

Product Introduction:
The Synchronized Chain Hydraulic Jacking System represents the pinnacle of heavy lifting technology for the storage tank industry. Engineered for extreme reliability and precision, this system employs a network of high-capacity hydraulic chain jacks operating under the command of a sophisticated central control unit. Its primary function is to execute the critical "tank lift" – raising the entire welded tank shell (excluding the bottom plate resting on the foundation) to a specific height. This controlled elevation is essential for accessing and welding the tank's annular plate (the joint between the tank bottom and the shell), inspecting the foundation, performing repairs, or facilitating relocation. The chain mechanism provides a direct, positive lift with minimal stretch or elongation, ensuring predictable and accurate movement essential for structural alignment.

Technical Parameter

System Total Capacity: 2000 Tons to 10,000+ Tons (Fully scalable).

Jack Configuration: 16 x 250 Ton Hydraulic Chain Jacks (Example for a medium-large tank).

Chain Size & Grade: 22mm or 26mm, Grade 120 Alloy Steel (DIN 5688 Type WA or similar).

Working Stroke per Jack: 500 mm.

Lifting Height per Lift: Typically 500mm - 1500mm (Requires re-stroking jacks for greater heights).

Control System: Programmable Logic Controller (PLC) with Color Touchscreen, featuring:

Real-time display of load (tonnage) at each jack.

Real-time display of position (height) of each jack.

Automatic synchronization mode with adjustable tolerance (±2mm typical).

Manual individual jack control mode.

Data logging and event recording.

Comprehensive alarm system (overload, desync, chain slack, low oil, etc.).

Hydraulic Power Unit: High-pressure (700 bar), high-flow unit with multiple pumps for speed, electric motor driven (Diesel option for remote sites). Includes accumulators for emergency lowering.

Safety Devices: Mechanical locking nuts on each jack cylinder, emergency stop buttons, pressure relief valves, chain slack sensors, structural overload protection in PLC.

Environmental Rating: IP65 for control panel & power unit (suitable for outdoor sites).
