Hydraulic Tank Jacking System:

Tank Jacking system uses dual-stage hydraulic cylinders to lift and horizontally build storage tanks from the top down (the return trip needs external force or dead load for returning). This enables the horizontal and vertical welding of tank shell can be conducted on the ground efficiently and safely, cooperated with submerged-arc automatic girth welding machines (AGW) and vertical welding machines (EGW).

Hydraulic tank jacking system with the flexibility to lift storage tanks of different capacities and weights that are compatible to various manual or automatic welding methods adopted by tank contractors across the globe.

We can handle the largest tank projects and we can do it safety with maximum saving of time.

Our jacks are mounted securely on the floor and using the massive cylinder as a beam, will support the structure even in higher wind loads.

Each HLD jacking module has it’s own hydraulic pump and reservoir. They  are linked to a central control that commands all aspects of the jacking operation.

Each standard HLD jacking module with 2 cylinders is capable of lifting 50,000 kg, which allows fewer jacks to raise a tank, it is designed with a large clearance from the tank shell that gives the workers extra room to quickly insert plates.

In operation, the cylinders are attached to the wall, the control loads the jack manually, or automatously via the addition of a PLC unit, then lift the structure holding tolerance within 2mm.

 
  • High quality, dual-stage hydraulic cylinders to lift and horizontally build storage tanks from the top down (the return trip needs external force or dead load for returning). This enables the horizontal and vertical welding of tank shell can be conducted on the ground efficiently and safely, cooperated with submerged-arc automatic girth welding machines (AGW) and vertical welding machines (EGW).
  • Specifications:
    • Capacity of storage tank jacking module is 25t
    • If appropriate quantity of modules are equipped, their storage jacking capacity can be up to 1500t
    • “One for five” oil supply method: every set of hydraulic power units are connected to 5 sets of hydraulic cylinders, avoiding the disadvantages of traditional centralized oil supply (too many oil pipes and too many oil leakage points, ensuring to minimize the environmental pollution)
  • Applications:
    • Inverse installation construction of petrochemical vertical cylinder type steel tank (hydraulic lifting method)
    • Steel liner inverse installation construction of power plant chimney
    • Vertical hoisting and lifting of super large objects
  • Main components
  •  5X customized hydraulic cylinder
  •  Hydraulic power unit
  •  May supplement: centralized control operation box and power operation box
