Principle of the 12t hydraulic jacks system
Principle of the erection system
The following short description gives the working procedure in outline. It can in certain details be modified when required.
Step 1. The tank bottom - plates are placed on the prepared foundation and welded together.
Step 2. The beams or lattice work of the roof are assembled and finally joined to the upper rim of the shell ring.
Step 3. The jacking equipment is installed in the tank. The plates of the second shell ring (next to the top ring) are positioned outside the first one.
