Our Advantage
Safety First Hydraulic Jacking System is the safest way to erect storage tank. The complete work is executed on ground level preventing risks of accidents. For decades, there has been not a single report which goes to prove its credibility in being the safest and most preferred method for storage tank construction. The popularity of hydraulic jack system has now discarded the need for a tall boom crane.
No Scaffolding Required
The jacking system requires various scaffolding and attachments to provide comfortable access for welding heights, but now all weldings can be done at ground level.
Easier Inspection
Welding inspectors can now perform ultrasonic or other non destructive tests on welds at ground level, which facilitates ease of inspection for better quality control. No more climbing up to perilous positions for welding inspectors.
Faster Erection
The shell plates are erected at ground level instead of being installed at the height of about 30 feet or more, saving construction time required for alignment of plates. The time and manpower required for lifting the plates to the height is eliminated. Construction work remains unaffected by rain or snow, since most work is done under the protection of the tank itself.
Tank Erection Top Downwards Cuts Construction Time And Cost Considerably :
New shell plates are constructed at ground level instead of being hauled up to about 30 feet heights or more, saving considerable time required for alignment of plates. The cumulative time required for lifting of men and material to heights is eliminated. Tank construction work remains practically unaffected by rain or snow, since most work is performed under the protection of the tank itself.
Most of the fabrication work is performed at ground level allowing for faster erection and reducing the risk of possible injuries
Eliminates the requirement of the crane
Faster erection
Cost of jacking equipment can be easily recovered after construction of 3 to 4 storage tanks or by erecting about 1200 tons of tankage. Jacking cost is approximately USD 50 per ton for 1200 tons
Example : Tank of 30 m diameter weighing about 300 tons needs 30 jacks of 12 ton each. Full cost of jacking equipment can be recovered in 4 such tanks.

Standard models suitable for 2500 mm shell width
Special models available for higher shell width
Manufactured under strict quality control norms

Trained operators are deputed for operation
Tank Construction Methodology:
First foundation is completed, base/bottom plates and top most shell plates are erected and welded. Roof structural, roof plates & top angle ring welded for truss supported roof tanks
Tank jacking equipment erection is complete and hydraulic connections are complete with the power pack
On energizing the power pack the shell plates along with roof is lifted by the hydraulic Jacks to the required height
Next shall course plates are erected and welded
Jacking units are lowered and connected to the new shell plates and operation is repeated for balance shell course
After the last shell course plates are welded in position, the jacking units are dismantled. Shell to bottom plates welding is completed
Advantages
Welding done at ground level
Easy access for inspecting quality of welding at each stage
Roof is fixed to the top shell plate from the commencement, rendering it stable against WIND-LOAD throughout the erection work
Guide trestles stabilise the tank at the bottom maintaining its circularity and accuracy
Need of scaffolding is eliminated
HIGHEST SAFETY achieved as working is carried out at ground level
ECONOMY – cost effectiveness achieved as labour & time required is minimised
