Bygging Jacking System

Safety First
Most work is done at ground level reducing risks of accidents. This is the safest and most preferred method for storage tank construction,discarding the need for a tall boom crane.
No Scaffolding required
The jacking system dispenses with elaborate scaffolding requirements required to provide access for welding at heights, since now all welding is done at ground level.
Welding at ground level
Since welding is done at ground level and not at heights, better quality is ensured and risk of accidents is "LOW"
Lesser Manpower
Work at ground level increases productivity thereby reducing the number of manpower required.
Faster Erection
Welding inspectors can now conduct ultrasonic or other non-destructive tests on welds at ground level, facilitating ease of inspection and hence better quality control. Therefore, now there is no need to climb to precarious heights for welding inspection.
Easier Inspection
New shell plates are to be erected ground level instead of being hauled up to about 30 heights or more saving precious construction time for alignment of plates.
Jacking used the world over
USA, Latin America, South America, Europe, CIS, Africa, Middle East, Australia, Asia… Storage tanks have been erected in 89 countries using our Hydraulic jacking system.
