Synchronized Chain Hydraulic Jacking System 12-120t Capacity

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.
