Product Introduction:
The Chain Lift Hydraulic Jacking System is an advanced, engineered solution designed specifically for the precise vertical lifting, lowering, and positioning of large-scale storage tanks during construction, maintenance, or relocation. Unlike traditional cable systems, it utilizes high-strength alloy steel lifting chains coupled with synchronized hydraulic power units. This system provides exceptional control, stability, and safety when handling massive cylindrical structures like oil, chemical, or water storage tanks, often weighing hundreds or thousands of tons. The core principle involves attaching hydraulic chain jacks radially around the tank's circumference to a lifting lug (or lifting band) welded to the tank shell. These jacks work in unison under a central control system to elevate or lower the entire tank structure smoothly and evenly.
Technical Parameter
Lifting Capacity per Jack: 100 Tons to 500 Tons (1000 kN to 5000 kN)
Standard Stroke per Jack: 300 mm to 1000 mm
Lifting Speed: 50 - 150 mm/min (Controllable)
Lowering Speed: 50 - 200 mm/min (Controllable)
Synchronization Accuracy: ±2 mm to ±5 mm (Depending on system size & control level)
Lifting Chain: Grade 100 or Grade 120 Alloy Steel, DIN 766 / 5687 / 5688 or equivalent.
Control System: PLC-based with touchscreen HMI, real-time load & position monitoring, auto-leveling, and emergency stop.
Power Unit: Hydraulic power pack (Electric or Diesel driven), pressure: typically 700 bar.
Number of Jacks: Configurable (8, 12, 16, 24+ common) based on tank diameter, weight, and lift points.
Safety Factor: Minimum 3:1 on all critical components (chains, hooks, cylinders).
Key Features:
Unmatched Stability & Control: Chain systems offer inherent rigidity compared to wire ropes, minimizing sway and providing superior positional stability during lifting/lowering.
High Precision Synchronization: Advanced PLC control ensures all jacks move in perfect unison, maintaining level lift within tight tolerances, crucial for tank integrity and foundation alignment.
Enhanced Safety: Multiple safety features: overload protection, emergency stop, chain slack detection, mechanical locking nuts/pins, and redundant system monitoring. High-strength chains are highly resistant to shock loads and damage.
High Load Capacity & Compactness: Chain jacks deliver immense lifting force from a relatively compact footprint, ideal for confined spaces around tank bases.
Durability & Reliability: Engineered alloy steel chains and robust hydraulic components ensure long service life and reliable performance in demanding industrial environments.
Smooth & Controlled Operation: Hydraulic actuation provides exceptionally smooth motion, essential for sensitive operations like setting tanks onto foundations or delicate supports.
Modularity & Scalability: Systems can be easily configured with the required number of jacks to handle tanks of virtually any size and weight.
Applications:
New Tank Construction: Lifting the completed tank shell off the ground after bottom welding to allow for annular plate welding and inspection.
Tank Relocation: Safely lifting and lowering tanks for moving them to new foundations or within a facility.
Tank Maintenance & Repair: Elevating tanks to replace/repaint foundations, replace bottom plates, or inspect/repair the tank base.
Foundation Replacement/Upgrade: Lifting the tank to allow demolition and reconstruction of the concrete ringwall or pad foundation.
Jacking for Roof Work: Providing controlled lift for roof installation, repair, or replacement.
Precise Setting: Final positioning of tanks onto piles, supports, or seismic isolation bearings with millimeter accuracy.
Widely Used In: Oil & Gas Terminals (Floating Roof Tanks, Fixed Roof Tanks), Petrochemical Plants, Refineries, Water/Wastewater Treatment Plants, Power Plants, LNG Storage, Large Silos.
