Hydraulic Tank Jacking Device is designed for jacking of storage tank with top-to-bottom construction method, which is innovated by NAEC using advanced modular design concept.
Compared with conventional type lifting system, NAEC Hydraulic Jacking System is modular design, each modular contains one power pack with 5 cylinder jacks. Cylinder is double tele type, also has adjustable stay. Pls see below picture(Yellow round means cylinders, Blue square means power supplies and main control).
NAEC Hydraulic Jacking System has bellow features:
Standard oil cylinder stroke is 2800mm, all work is done in the first shell height. It is very safe.
Unique design, more suitable for application of automatic welding machine. It matches with our specialized top-to-bottom girth welding machine to realize automatic welding of inside girth seam.
The lifting efficiency is high. For example, if shell height is 2.6m, it takes 15-20mins to lift the shell to the proper position.
Synchronism controlling is PLC supervised, if the hydraulic lifting system lifts not synchronized, it can be adjusted manually to ensure synchronism. In this way, the whole system will works very safely.
It can keep continuous lifting. Continuous lifting capability improves tank construction efficiency.
Modularized design ensures all jacks invested can work for different diameter tank, greatly reduce any possible waste.
By using NAEC hydraulic Jacking system, the jacking safety can be ensured, jacking efficiency is improved, and jacking operation is easier. NAEC hydraulic jacking system is reliable choice for storage tank construction companies. Such hydraulic jacking system has been used in many storage tank/ tank farm construction projects.
